WEBVTT 00:00:00.160 --> 00:00:07.600 Okay, Apple. I know this is going to sound a little crazy, but what if the 00:00:04.480 --> 00:00:09.360 MacBook Air actually moved some air 00:00:07.600 --> 00:00:14.639 around so it didn't thermal throttle after 2 minutes of any kind of work? 00:00:11.920 --> 00:00:19.680 Well, believe it or not, it can. And without even adding any fans, all we 00:00:17.119 --> 00:00:24.240 need is a couple of these. Mindus, I don't use a MacBook. Why should I care? 00:00:22.080 --> 00:00:29.279 And the answer is because anything Apple does, the entire rest of the copycat PC 00:00:26.640 --> 00:00:32.880 industry does like 3/4 later. So, if we can get them to adopt this kind of cool 00:00:30.880 --> 00:00:37.520 stuff, then maybe the rest of us have a chance. There's only a couple parts of 00:00:35.200 --> 00:00:42.239 this operation that might be a bit difficult to perform. Like this 00:00:40.640 --> 00:00:47.200 difficult segue to our sponsor, Ridge. Christmas 00:00:45.760 --> 00:00:51.760 is coming up and you know what that means? Buying presents for everyone. But 00:00:49.840 --> 00:00:57.039 Ridge can lessen the impact on your wallet, pun intended, with sales of up 00:00:54.000 --> 00:00:59.199 to 30% off. Go grab a fantastic stocking 00:00:57.039 --> 00:01:02.719 stuffer from Ridge down below. For our convenience, Four Systems has sent along 00:01:01.039 --> 00:01:06.640 an example of what this should look like when we're done. Emphasis on the should. 00:01:05.119 --> 00:01:10.880 There's no way mine will be that clean. Let's get started. Step one is to remove 00:01:08.799 --> 00:01:16.560 our back cover with a pentalobe 5 screwdriver. Do you know what you're doing? 00:01:13.280 --> 00:01:19.759 Yeah, mom. It would sure work better. 00:01:16.560 --> 00:01:21.920 Put on a jacket. Oh, wow. That's cool. 00:01:19.759 --> 00:01:24.560 Look at that. It's even still flat. And now that this is removed, the 00:01:23.119 --> 00:01:29.680 modification we'll be making to accommodate our air jets is to remove 00:01:26.880 --> 00:01:32.640 300 microns. 300 microns. Yeah, it's not very much. 00:01:30.479 --> 00:01:36.240 How are we going to Good luck, everybody. What happens if I break it? 00:01:34.720 --> 00:01:41.520 One sec. We have instructions. We have instructions. You were just 00:01:38.000 --> 00:01:42.720 going to let me struggle on my own. 00:01:41.520 --> 00:01:46.640 There's a whole bunch of stuff coming out. These are Apple's wild force 00:01:45.280 --> 00:01:50.560 cancelling speakers. Each of these apparently has three speakers in it. 00:01:48.560 --> 00:01:54.159 They sound really good. Or at least I think they do. We're never going to hear 00:01:51.759 --> 00:01:58.399 them. They are not going back in. Our next step is to remove the ribbon cable 00:01:56.399 --> 00:02:01.040 from the Mag Safe connector and then shimmy out the Mag Safe. How are we 00:02:00.000 --> 00:02:05.680 going to charge the thing? With the USB. With USB. Oh, we have no Mag Safe 00:02:04.079 --> 00:02:09.039 anymore. Did I mention yet that we're going to lose some functionality here? 00:02:07.280 --> 00:02:12.959 Cuz we are. The point of this is not that you can just go buy a For air jet 00:02:11.280 --> 00:02:19.040 at the store and then install it in your MacBook Air. to show how the system 00:02:15.760 --> 00:02:20.720 could be cooled better and fanlessly if 00:02:19.040 --> 00:02:25.440 Apple engineered it in in the first place. So, sorry to disappoint you, but 00:02:24.160 --> 00:02:30.000 it's still going to be really cool. Oh, look at that. I reconnected some things. 00:02:27.599 --> 00:02:33.920 One minor oversight is if you remove MagSafe and the keyboard. Did I mention 00:02:33.040 --> 00:02:38.239 we're not going to be able to use the keyboard? Don't worry about it. The point is we're going to have no way of 00:02:36.480 --> 00:02:41.680 turning the device on and using it. So, we have to enable a feature in macOS 00:02:40.080 --> 00:02:46.720 that allows us to boot it up if we have a USBC charger attached, not Mags safe. 00:02:44.879 --> 00:02:50.879 It's Apple logic. We found the setting. It's allow accessories to connect 00:02:48.560 --> 00:02:53.440 always. It's under privacy and security. Sure. Better to shut it down before we do 00:02:53.040 --> 00:02:57.519 this. Oh, I might have just killed it. You have to shut it down before you 00:02:56.319 --> 00:03:02.080 disconnect the battery sometimes. Yes. Oh, boy. Yeah, it's bending. This is 00:03:00.239 --> 00:03:06.000 making me very nervous. You're sure this is supposed to come up? Yes. Yes. 00:03:06.720 --> 00:03:13.040 I dare you to lick it. Context. What we're looking at right now 00:03:10.400 --> 00:03:18.879 is the power supply. Alex, I will not be licking it. And also the M2 chip with 00:03:16.159 --> 00:03:23.120 its DRAM right next to it, which raises an interesting question. Is this the 00:03:20.640 --> 00:03:26.879 whole cooler for the M2? Guess so. 00:03:24.080 --> 00:03:32.000 No wonder this sucks. Yes, Apple. There was clearly no better way to do this. 00:03:30.000 --> 00:03:36.640 Not even a little vapor chamber. Nothing. It does have a gap here. 00:03:35.200 --> 00:03:41.680 Do they have decent coolers on the latest generation Pros or Wait, we're still waiting for our samples. 00:03:39.440 --> 00:03:45.040 Yeah, when I say samples, I mean samples we bought. Apple doesn't send us stuff. 00:03:43.599 --> 00:03:51.040 It's like they don't like us for some reason. I don't know. We've never done anything 00:03:47.040 --> 00:03:52.400 awful to their computers ever. 00:03:51.040 --> 00:03:56.400 Here's the problem we're having a little think about right now. Our air jets need 00:03:54.640 --> 00:04:00.239 to be installed somewhere where they can draw air in through the filters on the 00:03:58.080 --> 00:04:04.720 top and then expel the air out the back of the system. We're thinking probably 00:04:02.239 --> 00:04:09.760 right around here. The issue is that's where Apple's keyboard and Touch ID 00:04:06.879 --> 00:04:14.959 daughterboard is. So, no keyboard. And Alex is sort of hoping 00:04:12.080 --> 00:04:19.600 that we could Yes. keyboard. It's not looking good. Would also be so 00:04:16.959 --> 00:04:22.160 easy to just move if these were not such fragile, stupid little connectors. 00:04:21.519 --> 00:04:28.400 Packed. Except for right there cuz we didn't pay enough. 00:04:26.000 --> 00:04:31.680 Okay. Hey, see not even ripped mostly a little. 00:04:31.173 --> 00:04:36.560 [laughter] Who needs a keyboard anyway? It's not even mechanical. Now comes the part 00:04:34.720 --> 00:04:42.639 where we drop all pretense of being careful and start cutting things. 00:04:38.400 --> 00:04:45.520 Goodbye audio jack ribbon cable. Oh. 00:04:42.639 --> 00:04:48.880 Oh no. Touch ID. Should have had Face ID. 00:04:47.199 --> 00:04:53.600 Now it's all coming together and you can see what the plan is going to be. We're 00:04:50.639 --> 00:04:59.520 going to have three AirJet minis here, here, and here. We are going to machine 00:04:57.600 --> 00:05:03.840 a little bit of extra space in the chassis so that there's actually room 00:05:00.960 --> 00:05:07.759 for them to intake air. And then we need a controller board for these things. 00:05:05.680 --> 00:05:11.440 Where is that going to go? Oh, that's why we ripped out the Mag Safe so we can 00:05:09.919 --> 00:05:14.400 actually connect this thing to power. We're just going to use a USB cable. 00:05:13.840 --> 00:05:20.000 Y nice. Our goal now is to get power to our air jets, which is done with this 00:05:18.479 --> 00:05:23.840 little board right here. Thing is though, uh, we don't have power going 00:05:22.000 --> 00:05:26.880 into this right yet. Now, you might be thinking that we could just take it off 00:05:25.600 --> 00:05:32.000 somewhere in here, but it's not quite that easy. First of all, uh from the 00:05:29.039 --> 00:05:36.880 battery, this connector is just super duper small. Probing, it's very 00:05:34.000 --> 00:05:41.520 difficult. And when they tried to, uh the whole thing went kablam. Also, you 00:05:39.440 --> 00:05:45.840 might be able to probe over here in sort of the power supply region of the main 00:05:43.440 --> 00:05:50.400 board, but uh they also [music] did that and it blew up again. So, instead, we're 00:05:48.560 --> 00:05:55.440 just going to be using USB power. You just simply pass the little thing 00:05:52.479 --> 00:05:58.240 through right here. Solder it together, making sure that you've already passed 00:05:56.800 --> 00:06:03.320 it through before you do that, and we should be good to go. Sorry, Mr. USB. 00:06:05.759 --> 00:06:11.440 Now, man, that's tight. You need to just 00:06:08.880 --> 00:06:15.160 squish this cable down a tiny bit or it won't go in at all. 00:06:16.560 --> 00:06:24.800 Not too bad. Now we have to attach the drive cables from our power to our air 00:06:21.199 --> 00:06:26.319 jets. This go right in here. For some 00:06:24.800 --> 00:06:32.160 strain relief, we're just going to fold these cables around like so. We got rid 00:06:29.840 --> 00:06:36.560 of the EMI shield, so we're going to be replacing that with more capton tape. 00:06:34.639 --> 00:06:41.039 There we go. Now, we just need to block off the rest of that mag safe hole using 00:06:38.720 --> 00:06:45.199 this tiny 3D printed [music] part. This is very important because we're going to 00:06:43.120 --> 00:06:49.360 be drawing in air from right here. It needs to cool the stuff on the logic 00:06:47.440 --> 00:06:53.280 board, come over and get exhausted over here. If we still have this gap, then 00:06:51.520 --> 00:06:56.880 the air just comes in there and it doesn't do what it needs to do. The next 00:06:55.440 --> 00:07:01.440 thing we have to do is put in this little TPU gasket. This right here just 00:06:59.360 --> 00:07:05.599 prevents recirculation of our hot air. We want all of it going out instead of 00:07:03.199 --> 00:07:09.120 coming on back in. But before we do that, we need to make sure that our air 00:07:06.880 --> 00:07:13.840 jets can go in here nice and tight. Means we need a little bit of vacuum 00:07:11.919 --> 00:07:16.944 lube. that. Boom. I I think I [music] have way too much. [laughter] 00:07:18.800 --> 00:07:24.880 Next thing we'll need is a piece of graphite. This acts as a heat spreader. 00:07:22.639 --> 00:07:30.560 Uh, okay, not a heat spreader, but a spreader of heat to make sure that when 00:07:28.319 --> 00:07:34.000 we have our vapor chamber sitting on top of it, we're not going to get a bunch of 00:07:32.240 --> 00:07:38.319 heat from that through to the keyboard, creating a hot spot. Take that, 5minute 00:07:36.319 --> 00:07:41.039 crafts. Look at how straight that line is. Would you look at that? There's a 00:07:39.919 --> 00:07:48.080 whole system for this and everything. And it's got a little split on the bottom. Nice. Oh, gross. Our t-shirts 00:07:46.160 --> 00:07:51.599 also work great as a cleaning cloth. ltstore.com. 00:07:50.240 --> 00:07:56.400 Ooh. While we're waiting for the next step, these are really cool. They're USB 00:07:54.160 --> 00:08:00.960 PD cables. So, you can see it's labeled 9V 5 amps. That's because if you were to 00:07:59.360 --> 00:08:07.039 plug in a regular cable, it would be limited to 5 vol and I believe.5 amps. 00:08:04.639 --> 00:08:10.639 That's because for USB PD to activate, so the higher amperages, higher 00:08:08.800 --> 00:08:15.120 voltages, there has to be a handshake that goes on. So these special cables 00:08:13.039 --> 00:08:18.479 have the handshake chip inside them. So you just plug them in and then they can 00:08:16.800 --> 00:08:21.360 grab whatever voltage they need for whatever device you want to plug in. In 00:08:20.000 --> 00:08:27.120 this case, their little controller board. Okay, now it's time to cut off 00:08:23.120 --> 00:08:29.759 our antenna. So we make a little 00:08:27.120 --> 00:08:36.479 incision and then we should be able to just peel it off. Very important though 00:08:34.240 --> 00:08:41.599 at this stage that I don't slice myself open. One. And two, that I don't break 00:08:39.680 --> 00:08:45.120 this plastic piece right here. I don't want to break this. 00:08:44.080 --> 00:08:49.839 Come on. O, don't worry. You guys are good. You're good. You're good. It's all good. It's 00:08:47.600 --> 00:08:53.839 all good. The Fore people are here to like show us how to use all this stuff. 00:08:53.600 --> 00:08:59.680 It's their It's their MacBook. I mean, I don't want it. It has no keyboard, no 00:08:57.760 --> 00:09:03.040 Wi-Fi, no Mag Safe. Don't worry, we're going to get to the part where we show 00:09:00.880 --> 00:09:08.240 you guys how if it was integrated from the start, this could be done. My pliers 00:09:06.320 --> 00:09:14.080 are stuck together now. I'm not going to break it. I guarantee it. 00:09:12.240 --> 00:09:19.399 Did I guarantee it or what? Apparently, we need to cut it now. Don't break it. 00:09:15.839 --> 00:09:19.399 Do break it. 00:09:22.800 --> 00:09:27.279 Oh, yeah. Oh, yeah. There we go. Now for 00:09:25.920 --> 00:09:32.560 the really fun part. We're gonna put some double-sided captain tape on our air jets, and I'm going to show you guys 00:09:30.560 --> 00:09:36.320 exactly how we're going to fix the thermals on this thing. The best part of 00:09:34.640 --> 00:09:40.399 these kinds of videos is that I hear from them often enough that I know 00:09:38.080 --> 00:09:44.240 people at Apple watch our channel. So, that means if they don't do anything 00:09:41.839 --> 00:09:48.080 about this, it's cuz they decided they don't care. That reminds me, this is a 00:09:46.000 --> 00:09:51.839 very unusual application for these air jets. Normally, you would use the copper 00:09:50.240 --> 00:09:56.800 spreader at the bottom, and you would put that directly against the dye or the 00:09:54.640 --> 00:10:02.080 chip that you're trying to cool, but in this case, there just isn't enough room 00:10:00.000 --> 00:10:07.440 in this device for that to be possible. So, instead, it's being used as more 00:10:04.880 --> 00:10:10.720 like a crazy [snorts] lowprofile exhaust fan, cuz you wouldn't be able to get a 00:10:08.880 --> 00:10:16.000 traditional fan in here. And there are other advantages besides the thinness. 00:10:12.880 --> 00:10:19.200 These things generate over 1,700 pascals 00:10:16.000 --> 00:10:21.600 of static pressure. So, what that means 00:10:19.200 --> 00:10:27.040 is when you jam them in here, okay, these are little exhaust shrouds. Oh, 00:10:24.000 --> 00:10:30.880 boy. There we go. 00:10:27.040 --> 00:10:33.760 Ah, the intake here is able to draw air 00:10:30.880 --> 00:10:39.360 from tiny little gaps in the chassis over any incidental heat generating 00:10:36.480 --> 00:10:43.360 component like the power delivery or oh, I don't know, the nan flash for your 00:10:41.040 --> 00:10:48.079 storage. Suck it into the filtered intake and then push it out of the 00:10:45.680 --> 00:10:51.279 system. Oh, wait. There's more. Hold on. Okay, let's get the other two installed 00:10:49.600 --> 00:10:56.240 and I can show you guys the other little bit of magic that we've got going on 00:10:52.880 --> 00:10:58.240 here. Ah, yes. A replacement for that 00:10:56.240 --> 00:11:02.160 really excellent heat spreader we had before. You'll notice that our vapor 00:11:00.160 --> 00:11:06.240 chamber here is connected to a heat sink fin stack that is extremely dense. You 00:11:04.720 --> 00:11:12.160 would have no hope of pulling air through that with a conventional fan. 00:11:08.399 --> 00:11:14.640 But with one of these bad boys, you can 00:11:12.160 --> 00:11:18.800 position this right next to these. And we're going to use some little uh some 00:11:16.399 --> 00:11:23.440 little foamy bits to kind of guide our air flow. You can make it so that their 00:11:20.800 --> 00:11:26.720 intake is pulling air through there, saturating that air with heat, and 00:11:25.600 --> 00:11:33.519 throwing it out of the back of the system. That's the sound it makes, by the way. I'm just kidding. It's actually 00:11:30.320 --> 00:11:35.839 very quiet. You'll see later. 00:11:33.519 --> 00:11:39.920 And presto, Chenjo. All the cable management is done. I 00:11:38.480 --> 00:11:45.680 would have done this on camera, but it took a very long time. And also I had 00:11:42.959 --> 00:11:49.440 for help cuz it involved Y cables and like cutting some of the Y cables and we 00:11:47.920 --> 00:11:52.720 had to put these little daughterboard things over here instead of over here 00:11:51.040 --> 00:11:56.320 because otherwise there'd be a bulge on the bottom and we'd hate to have a bulge 00:11:54.240 --> 00:12:00.440 on our MacBook and be like, "Wow, MacBook, what you got in there?" 00:12:02.399 --> 00:12:05.399 Ow. 00:12:09.600 --> 00:12:14.200 Okay, let's get this trackpad reattached. 00:12:14.240 --> 00:12:20.800 Oh, what a weird thing that it won't turn on at all even though it does have 00:12:18.800 --> 00:12:24.720 battery without me plugging in a charger. That was that software setting 00:12:23.040 --> 00:12:28.673 that we enabled so that it would be able to turn on. Please turn on. Ah, yes. 00:12:26.959 --> 00:12:31.519 Good. [laughter] Yeah, it'll take about 3 minutes for it 00:12:30.959 --> 00:12:36.320 to turn on. 3 minutes. Forgot the keyboard doesn't work 00:12:34.720 --> 00:12:44.880 anymore. May not have a working keyboard on my MacBook, but I do have this. Boom. 00:12:41.040 --> 00:12:47.680 Wow. So seamless. This is a stupid phone 00:12:44.880 --> 00:12:53.120 that Reddit made me use. Yes. All right. This is our original 00:12:50.240 --> 00:12:57.600 that we were going to try to machine 30 hundredths of a millimeter off of, but 00:12:55.279 --> 00:13:01.120 then it turned out our equipment wasn't really set up for that. So here's the 00:12:59.279 --> 00:13:06.240 one that Freud did ahead of. Really? That little makes a difference? I can 00:13:02.880 --> 00:13:07.920 barely even catch my fingernail on this. 00:13:06.240 --> 00:13:13.519 Hey, I can hear the air jets going now, though. So, you just need about 400 microns of 00:13:11.200 --> 00:13:17.360 gap. 400th of a millimeter. Right. Right. Right. Right. Right. The 00:13:15.040 --> 00:13:21.839 point of this is not to make room for the air jets. The point of this is to 00:13:19.519 --> 00:13:28.959 make room for the intakes of the air jets. They only need about 400 microns. 00:13:25.360 --> 00:13:32.000 So that's what 4 hundreds of a 00:13:28.959 --> 00:13:34.880 millimeter in order to get enough space 00:13:32.000 --> 00:13:39.680 that the air can go into those filtered intakes. And again, this is because the 00:13:36.880 --> 00:13:44.709 static pressure of these things is so flipping high. All right, let's put this 00:13:42.240 --> 00:13:44.709 on. [music] 00:13:45.600 --> 00:13:50.160 Do we need to take some off of the back cover? Yeah, but it has all the static pressure. It doesn't even need a proper 00:13:49.760 --> 00:13:54.160 outlet. Yeah, but look at look at this. I thought that's the whole point of the 00:13:53.120 --> 00:13:59.600 product. Oh, can't have that gap. Yeah. What is this? A Model Y? 00:13:57.920 --> 00:14:04.320 Wait, how flush is it supposed to be? Yeah. So, that's about right. Yeah, 00:14:01.040 --> 00:14:06.560 we're good. Cool. Nice. I can definitely 00:14:04.320 --> 00:14:10.000 hear the air jets working. Now, before you say it, incense can be perfectly 00:14:08.320 --> 00:14:14.040 manly. It's all in how you light it, 00:14:16.000 --> 00:14:24.720 huh? Woo! No moving parts, guys. 00:14:21.199 --> 00:14:26.560 Pretty cool, huh? So, we are not pulling 00:14:24.720 --> 00:14:30.560 as much from our intake as we might have thought we were. Where the devil are we 00:14:28.720 --> 00:14:35.920 pulling air into this thing then? Where is it drawing air in then? Feel like I'm 00:14:32.639 --> 00:14:38.880 conducting some kind of like uh fortune 00:14:35.920 --> 00:14:42.639 reading the Mac. Yes, your MacBook will not need Apple Care. Don't bother 00:14:40.959 --> 00:14:47.279 spending the extra money on it. It will live a long life. Now, it's time for the 00:14:44.800 --> 00:14:54.320 moment of truth. We ran Cinebench R23 on our three systems. a stock M2 MacBook 00:14:50.399 --> 00:14:57.360 Air, our modified M2 MacBook Air, and an 00:14:54.320 --> 00:14:59.279 M2 MacBook Pro. And in a stunning 00:14:57.360 --> 00:15:05.839 development, they all performed exactly the same. But we expected that. Yes, 00:15:02.800 --> 00:15:08.079 this flimsy piece of metal can allow the 00:15:05.839 --> 00:15:13.040 M2 to run at full performance as long as you only do a short run. But what 00:15:10.320 --> 00:15:16.320 happens if we do a 30 minute test? Never mind your 10-minute timer, Alex. This 00:15:14.639 --> 00:15:22.240 has only been running for 4 minutes and we can already see that our unmodified 00:15:19.519 --> 00:15:30.079 MacBook Air is down to just shy of 17 watts and our modified 00:15:25.920 --> 00:15:32.399 one is just shy of 20. [music] 00:15:30.079 --> 00:15:37.040 And more power means we must be getting more performance. Now what's interesting 00:15:34.480 --> 00:15:42.480 is both of these are running at over 100°. So they're clearly both thermally 00:15:40.160 --> 00:15:48.800 limited in a sense. Processor package proximity is 5° cooler 00:15:47.040 --> 00:15:52.240 on this one. Remember we talked about how these things have super high static 00:15:50.720 --> 00:15:57.680 pressure so they can pull air through little tiny gaps in things. That's a 00:15:55.440 --> 00:16:03.600 huge advantage. We're almost 8 minutes in and we're all the way down to 15.7 00:16:01.199 --> 00:16:06.560 watts here. still holding steady at 20 watts here, which I just realized I 00:16:05.360 --> 00:16:13.199 haven't given you guys an update on the MacBook Pro, is actually higher than the 00:16:09.680 --> 00:16:15.040 MacBook Pro, which is at 19 12. At the 00:16:13.199 --> 00:16:23.360 20 minute mark, we are all the way down to 14 1/2 watts on our unmodified air, 00:16:19.440 --> 00:16:25.839 19 watts on our modified air, and okay, 00:16:23.360 --> 00:16:28.959 20 watts on the MacBook Pro. Okay, so it turns out building cooling into the 00:16:27.440 --> 00:16:33.600 design of the product is a good thing, but there's no reason that something 00:16:31.279 --> 00:16:37.440 like this couldn't be integrated if Apple decided to do it. The control 00:16:35.759 --> 00:16:41.759 board, for example, could be integrated into the motherboard. And the for 00:16:39.920 --> 00:16:45.519 systems team, bless their hearts, even if it's a little bit desperate looking, 00:16:43.519 --> 00:16:49.360 actually calculated the remaining internal volume and even though the 00:16:47.440 --> 00:16:54.480 geometry doesn't work right now, figured out that yes, in fact, you could fit air 00:16:52.240 --> 00:16:58.720 jets in it if you were to uh want to do that. Hint, hint, wink, wink, nudge, 00:16:55.920 --> 00:17:04.079 nudge. Hi, Apple. There's more to the story than just power consumption and 00:17:00.480 --> 00:17:06.240 temperatures of the internal component. 00:17:04.079 --> 00:17:09.679 Okay, that's fine. Let's talk about the exterior [music] 00:17:08.400 --> 00:17:16.079 temperatures. Alex, you got thermal camera running already? Yeah. Stock MacBook Air hotspot 49. 00:17:14.240 --> 00:17:21.439 That's like burn you hot. Burn you over time hot. Let's not 00:17:18.720 --> 00:17:25.360 overblow this. And it's on like three keys. How about our four systems 00:17:23.600 --> 00:17:28.960 modified unit? Mhm. That's still really hot. 00:17:27.439 --> 00:17:33.840 Yeah, but it's like 48 I'd say within margin of error. 00:17:31.520 --> 00:17:38.480 What's interesting though is it has a bit of a different spread pattern to it. 00:17:36.640 --> 00:17:45.200 Way less if it's hot. Like there's only just a tiny little bit right over top of 00:17:41.440 --> 00:17:47.120 where the CPU is. Whereas on the not 00:17:45.200 --> 00:17:51.840 actually cooled one how much of the heat is just soaking into the chassis and 00:17:49.440 --> 00:17:54.240 then eventually dissipating. Yeah. 00:17:52.799 --> 00:17:58.799 Is that something that I would actually notice with my hands though? It is 00:17:56.640 --> 00:18:03.360 noticeable. Not much though. 00:18:00.960 --> 00:18:10.080 As for the MacBook Pro, I mean, it has cooling up. Final render 00:18:06.720 --> 00:18:11.440 done. There it is. 8,191 points, which 00:18:10.080 --> 00:18:16.559 it's actually kind of impressive when you consider how little of its power budget was still available to it because 00:18:14.559 --> 00:18:22.960 of thermal throttling. As for our modified one, 8,611 00:18:19.760 --> 00:18:26.000 points. So, instead of losing 600 00:18:22.960 --> 00:18:29.200 points, we lose only about two. As for 00:18:26.000 --> 00:18:31.039 our Pro, 8690. [music] 00:18:29.200 --> 00:18:36.320 So marginally faster than either machine. In conclusion then, not a practical DIY 00:18:34.400 --> 00:18:40.640 upgrade, but the technology is super cool. The fact that they can build this 00:18:38.080 --> 00:18:45.840 into something so slim [music] that they can move this kind of air with no moving 00:18:43.679 --> 00:18:50.000 parts in the cooler whatsoever just using PZO electrics. [music] I said it 00:18:47.760 --> 00:18:53.679 before and I'll say it again. I am very excited for the future of this 00:18:51.280 --> 00:18:59.440 technology and very excited to tell you about our sponsor, Cson Sonic. They make 00:18:56.160 --> 00:19:00.880 power supplies so great that frankly I'd 00:18:59.440 --> 00:19:05.440 take a bullet for them. That's only slightly hyperbole. I mean, look at the 00:19:02.559 --> 00:19:09.600 Prime TX1000. Its hybrid fan control system lets you keep your system quiet 00:19:07.280 --> 00:19:14.400 without creating a real life game of the floor is lava. And it's got an 80 plus 00:19:12.160 --> 00:19:19.600 platinum rating for supreme power efficiency. RGB frivolous cosmetics. 00:19:17.520 --> 00:19:23.280 What? Why would CIC add those things when they can put that money toward 00:19:21.440 --> 00:19:26.880 power? UNLIMITED 00:19:25.039 --> 00:19:30.960 POWER. [screaming] ALSO, IT'S backed by a 12-year warranty. 00:19:29.440 --> 00:19:34.960 And should you need to use that warranty, their customer support is 00:19:33.280 --> 00:19:39.520 excellent. So, if you want a reliable power supply for your next build or even 00:19:36.880 --> 00:19:42.640 an upgrade, start by checking out CIC at the link below. If you guys enjoyed this 00:19:41.440 --> 00:19:47.520 video, you might want to check out the much deeper look we took at this tech at 00:19:44.559 --> 00:19:52.480 Comp Computex 2023, where we even got to completely disassemble an airjet and 00:19:50.240 --> 00:19:57.520 show you guys how the inner workings work, or at least as much as we could 00:19:54.640 --> 00:20:00.320 see it. There's no moving parts, so it's basically magic.
