WEBVTT 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 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 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 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 00:00:21.200 --> 00:00:25.760 alike. The fans in your computer are rattling to the point it's driving you insane. 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 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 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. 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, 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. 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 00:00:53.200 --> 00:00:58.920 fans can rattle against the case and cause all kinds of racket. 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 00:01:03.800 --> 00:01:08.400 a couple drops of machine oil, assuming the fan isn't sealed. 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. 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 00:01:17.720 --> 00:01:23.760 components with you on an airplane, say to a faraway land event, maybe on a mountain. 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 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 00:01:35.560 --> 00:01:39.360 lithium battery. These batteries can be a fire hazard. 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 00:01:44.000 --> 00:01:47.700 the aircraft itself or incapacitation of the pilots. 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, 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 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 00:02:05.120 --> 00:02:10.340 jostled around in flight, so you might want to take those out and pack them separately. 00:02:10.340 --> 00:02:14.540 And yes, you can take an AIO water cooler through as well, despite the restriction on 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 00:02:21.380 --> 00:02:25.380 playing at higher resolutions or settings, we often see people ask if they can add more 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. 00:02:32.300 --> 00:02:37.220 VRAM on modern graphics cards is soldered on and not expandable. 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 00:02:41.940 --> 00:02:46.860 flows between them, meaning that expandable memory would likely sacrifice performance 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 00:02:52.860 --> 00:02:57.860 distant past, trying to jury-rig additional VRAM modules under your card these days with 00:02:57.860 --> 00:03:03.420 a soldering iron probably won't work and could even end up breaking your expensive 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. 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 00:03:11.660 --> 00:03:17.060 enough VRAM for the games you want to play.
