00:00:07.319 --> 00:00:14.400
so one of my followers on Twitter asked for an update on the wife PC as you guys

00:00:11.840 --> 00:00:19.199
may or may not recall I rearranged the airflow configuration cuz I was trying

00:00:16.440 --> 00:00:24.279
to avoid the default config which is these fans blowing out and these fans

00:00:21.920 --> 00:00:29.359
sucking air in um I was trying to avoid the default configs tendency to

00:00:26.439 --> 00:00:34.360
accumulate dust rings on the front fan Grill so so uh what I at first had

00:00:32.160 --> 00:00:38.680
planned to do was create a positive air pressure environment but that didn't

00:00:35.800 --> 00:00:42.360
really help because um anywhere where air was being drawn in I was still

00:00:40.280 --> 00:00:49.360
getting that uh that dust accumulation so what I've gone with now is a single

00:00:46.000 --> 00:00:52.160
intake at the back so that is running

00:00:49.360 --> 00:00:58.120
off of the CPU fan header with a voltage reducer in line so that it's running uh

00:00:55.160 --> 00:01:01.120
nice and quiet and nice and slow uh actually the sound you hear right now

00:00:59.320 --> 00:01:06.080
isn't the fat but actually it's the coil wi from the GPU cuz I have uh f mark as

00:01:04.199 --> 00:01:11.000
well as Prime 95 running right now so that you guys can see what the temperatures are like the fact that it's

00:01:09.000 --> 00:01:16.520
off the ground also helps a fair bit in terms of accumulating dust inside so

00:01:13.960 --> 00:01:22.759
it's uh yeah far less far less likely far less uh um liable to do that so

00:01:20.720 --> 00:01:28.840
let's go ahead and open it up going to show you guys

00:01:25.600 --> 00:01:31.400
uh what the guts are looking like these

00:01:28.840 --> 00:01:37.119
days so I did end up changing the

00:01:34.479 --> 00:01:41.159
motherboard oops there goes the Wi-Fi antenna well whatever so I didn't end up

00:01:39.680 --> 00:01:48.159
changing the motherboard right now I've got an MSI z68 a gd80 in there nice

00:01:44.399 --> 00:01:49.840
high-end board uh robust cooling on the

00:01:48.159 --> 00:01:54.600
voltage regulator modules which is good cuz I don't have a whole lot of cooling

00:01:51.880 --> 00:01:59.880
otherwise in this system so the two top fans are disabled they are off and there

00:01:58.000 --> 00:02:04.119
are no fans in the front so that is how how I'm keeping those dust rings out and

00:02:02.640 --> 00:02:08.479
I'm maintaining the positive air pressure just by having just one intake

00:02:06.159 --> 00:02:13.080
fan and it might be positive it might actually be more neutral because this is

00:02:10.599 --> 00:02:17.000
also an exhaust so this is pulling heat away from the

00:02:14.400 --> 00:02:22.120
GPU which is running quite toasty but that's to be expected it is running firm

00:02:18.640 --> 00:02:24.400
Mark which also has a single 120 mm fan

00:02:22.120 --> 00:02:27.920
running on the aftermarket cooler that is on there so that is pretty much it

00:02:26.840 --> 00:02:34.080
there's nothing really in the front of the case that needs to be cooled all we've got is SSD in here there are no

00:02:31.200 --> 00:02:39.440
hard drives this system relies 100% on network storage for its mass storage you

00:02:36.560 --> 00:02:43.239
can see the uh configuration of that video card so there's a bunch of heat

00:02:41.200 --> 00:02:48.280
sinks and whatnot all over it that's a 5870 it does still have a what is in

00:02:46.920 --> 00:02:55.599
there it's a 2600k as well as 8 gigs of Linus Edition

00:02:52.280 --> 00:02:58.480
ocz memory and azente X Mystique that's

00:02:55.599 --> 00:03:03.400
an older PCI sound card as well as a Gigabyte Wi-Fi Bluetooth card uh in

00:03:01.800 --> 00:03:07.120
there as well so the config hasn't changed much I just redid the

00:03:04.959 --> 00:03:11.200
motherboard I unplugged all the fans I switched the power supply around so that

00:03:09.400 --> 00:03:14.480
this would act as an exhaust for the hot air coming off of the graphics card

00:03:12.959 --> 00:03:18.000
because that's really really toasty and I didn't want to blow it the other way

00:03:16.080 --> 00:03:24.400
up towards the CPU Cooler because especially in a uh in a heavy load

00:03:21.560 --> 00:03:31.120
environment running the CPU passive like that is uh is pretty pretty tough It's

00:03:28.720 --> 00:03:35.120
really asking for lot now bear in mind guys this system is not overclocked in

00:03:33.360 --> 00:03:39.720
any way sorry I'm just adjusting something there I want to close this up

00:03:37.040 --> 00:03:43.920
here before I uh show you guys anymore hold on I'm

00:03:41.879 --> 00:03:49.200
just going to let the camera hang for a bit I apologize if this is like motion

00:03:46.680 --> 00:03:52.920
sickness inducing because there's just nothing else I can really do with it

00:03:50.720 --> 00:03:57.040
right now okay there case is closed up CU I want to show you guys uh closed

00:03:54.599 --> 00:04:04.280
side panel temperatures when I show you the prime 95 uh fur mark temps that are

00:04:01.280 --> 00:04:07.360
going on in here so again the system's

00:04:04.280 --> 00:04:09.000
not very loud that coil wine you hear is

00:04:07.360 --> 00:04:13.159
from the graphics card it'll turn off when uh when we turn off firmar fmar

00:04:10.799 --> 00:04:16.600
really does a number on graphics cards and I found especially the last few

00:04:14.760 --> 00:04:22.880
Generations AMD cards uh well they they whine a little

00:04:19.079 --> 00:04:25.120
bit all right here we go so CPU temps

00:04:22.880 --> 00:04:30.280
with uh eight threads of prime 95 are around 60° which are Super acceptable

00:04:28.680 --> 00:04:36.240
and firm ark's been running for the last little bit here and it looks like we're

00:04:32.120 --> 00:04:38.720
going to Peak around that sort of 76 to

00:04:36.240 --> 00:04:44.080
77 down to 76 oh look at that good timing we just hit the peak right around

00:04:41.440 --> 00:04:46.560
uh right around the time that we stopped uh that we stopped filming here and I

00:04:45.199 --> 00:04:52.560
stopped talking about it so you can see now it's really balanced itself out a

00:04:49.039 --> 00:04:55.120
fair bit so I think that pretty much uh

00:04:52.560 --> 00:05:00.400
covers it so the 5870 is more than happy running at around 75 80° underload and

00:04:58.639 --> 00:05:06.600
if we go ahead and turn all of this stuff off so if we stop our torture test

00:05:04.759 --> 00:05:11.759
put that away turn off fur Mark you're going to see that idle temperatures are

00:05:08.960 --> 00:05:16.199
very very good as well so like I said wouldn't recommend overclocking like

00:05:13.320 --> 00:05:21.680
this but if you have a case that is well ventilated in terms of just allowing

00:05:18.880 --> 00:05:26.759
passive air flow to go through it you know heat does tend to rise a little bit

00:05:24.600 --> 00:05:31.639
um you can get away with very few fans so there's only a few fans okay here

00:05:30.000 --> 00:05:37.000
much quieter now that was that coil wine from the graphics card before so very

00:05:33.560 --> 00:05:38.600
few fans 120 mil or sorry 140 mil here

00:05:37.000 --> 00:05:41.759
120 mil in the power supply and then that 120 mil directly on the video card

00:05:40.360 --> 00:05:46.440
and that's about it I mean if you didn't have a video card and you had like a

00:05:43.759 --> 00:05:52.039
passive power supply like uh like this x series one from cic here you could get

00:05:49.039 --> 00:05:54.479
away with just a single a single cooling

00:05:52.039 --> 00:05:58.759
fan blowing air towards that heat sink and that's about it remember guys that

00:05:56.479 --> 00:06:04.720
CPU is technically not 100% passive cuz I do have that near nearby fan blowing

00:06:01.039 --> 00:06:05.880
air at it so uh I think that pretty much

00:06:04.720 --> 00:06:10.360
covers it I think it's going to be a while before this settles down into an

00:06:08.319 --> 00:06:14.000
into an idle reading here but whatever you guys get the point Thank you for

00:06:11.479 --> 00:06:17.479
checking out this update on my video blog and don't forget to subscribe to

00:06:15.319 --> 00:06:21.000
L's Tech tips oh yeah for those of you who are

00:06:19.720 --> 00:06:27.520
definitely going to ask that's the fractal design Arc midi

00:06:23.319 --> 00:06:27.520
case love it
