1 00:00:00,000 --> 00:00:04,440 Have you ever had a tech question that seemed simple, but you couldn't find an answer to 2 00:00:04,440 --> 00:00:08,840 it? And we're a little too afraid to post on a forum, lest you incur the scorn of people 3 00:00:08,840 --> 00:00:15,800 who live and breathe tech? It's intimidating. We're gonna answer some real questions we found online that will hopefully help some 4 00:00:15,800 --> 00:00:21,200 of you, too. Let's start out with one that affects both the hardcore gamer and the home office worker 5 00:00:21,200 --> 00:00:25,760 alike. The fans in your computer are rattling to the point it's driving you insane. 6 00:00:25,760 --> 00:00:30,360 How do you fix it? Well, with all the wires that can cross every wish way inside of a computer case, it's 7 00:00:30,360 --> 00:00:34,600 entirely possible that one of them is hitting up against your fan blades if you've bumped 8 00:00:34,600 --> 00:00:40,780 your system recently. So, do a quick sanity check and look inside your PC for any physical obstructions. 9 00:00:40,780 --> 00:00:45,040 If your fan blades aren't running into anything, try cleaning off any dust you see on them, 10 00:00:45,040 --> 00:00:49,480 as a thick enough layer can also throw off the motion of the blades and make them rattle. 11 00:00:49,480 --> 00:00:53,200 Another good idea is to make sure they're all screwed inside your case snugly, as loose 12 00:00:53,200 --> 00:00:58,920 fans can rattle against the case and cause all kinds of racket. 13 00:00:58,920 --> 00:01:03,800 But if none of that solves your problem, you can try lubricating the fan's bearings with 14 00:01:03,800 --> 00:01:08,400 a couple drops of machine oil, assuming the fan isn't sealed. 15 00:01:08,400 --> 00:01:13,920 As a last resort, just replace the fan. You don't need to spend much money to get one that'll actually stay quiet. 16 00:01:13,920 --> 00:01:17,720 Now, let's move on and talk about what you should do if you need to take a PC or computer 17 00:01:17,720 --> 00:01:23,760 components with you on an airplane, say to a faraway land event, maybe on a mountain. 18 00:01:23,760 --> 00:01:29,400 Is this something that should cause you concern? Well, in terms of getting through security or a baggage screening, you shouldn't have 19 00:01:29,400 --> 00:01:35,560 too many problems. The main electronic item that you can't put in your checked baggage these days is a loose 20 00:01:35,560 --> 00:01:39,360 lithium battery. These batteries can be a fire hazard. 21 00:01:39,360 --> 00:01:44,000 And fires have been the cause of many infamous plane crashes, whether it's from damage to 22 00:01:44,000 --> 00:01:47,700 the aircraft itself or incapacitation of the pilots. 23 00:01:47,700 --> 00:01:54,620 They are allowed on carry-on bags, though. If there's a fire in the passenger cabin, someone can at least notice and put it out, 24 00:01:54,620 --> 00:01:59,780 hopefully. But the average desktop PC shouldn't have a lithium battery, so you shouldn't have issues 25 00:01:59,780 --> 00:02:05,120 at security. The bigger thing to keep in mind is that heavy parts, especially graphics cards, can get 26 00:02:05,120 --> 00:02:10,340 jostled around in flight, so you might want to take those out and pack them separately. 27 00:02:10,340 --> 00:02:14,540 And yes, you can take an AIO water cooler through as well, despite the restriction on 28 00:02:14,540 --> 00:02:21,380 liquids. This is special liquid. With big-name game titles asking for more and more VRAM these days, especially if you're 29 00:02:21,380 --> 00:02:25,380 playing at higher resolutions or settings, we often see people ask if they can add more 30 00:02:25,380 --> 00:02:32,300 VRAM to their graphics card. In short, the answer is unfortunately no, you can't even download it. 31 00:02:32,300 --> 00:02:37,220 VRAM on modern graphics cards is soldered on and not expandable. 32 00:02:37,220 --> 00:02:41,940 Modern VRAM has to be rather tightly integrated with the GPU itself due to how quickly data 33 00:02:41,940 --> 00:02:46,860 flows between them, meaning that expandable memory would likely sacrifice performance 34 00:02:46,860 --> 00:02:52,860 and reliability. Although a few cards that actually had slots for additional VRAM existed in the fairly 35 00:02:52,860 --> 00:02:57,860 distant past, trying to jury-rig additional VRAM modules under your card these days with 36 00:02:57,860 --> 00:03:03,420 a soldering iron probably won't work and could even end up breaking your expensive 37 00:03:03,420 --> 00:03:08,140 card. If you're hitting VRAM limits, turn down your settings and play at a lower resolution. 38 00:03:08,140 --> 00:03:11,660 And if you're in the market for a new card, make sure that you're picking one that has 39 00:03:11,660 --> 00:03:17,060 enough VRAM for the games you want to play.
