Have you ever had a tech question that seemed simple, but you couldn't find an answer to
it? And we're a little too afraid to post on a forum, lest you incur the scorn of people
who live and breathe tech? It's intimidating. We're gonna answer some real questions we found online that will hopefully help some
of you, too. Let's start out with one that affects both the hardcore gamer and the home office worker
alike. The fans in your computer are rattling to the point it's driving you insane.
How do you fix it? Well, with all the wires that can cross every wish way inside of a computer case, it's
entirely possible that one of them is hitting up against your fan blades if you've bumped
your system recently. So, do a quick sanity check and look inside your PC for any physical obstructions.
If your fan blades aren't running into anything, try cleaning off any dust you see on them,
as a thick enough layer can also throw off the motion of the blades and make them rattle.
Another good idea is to make sure they're all screwed inside your case snugly, as loose
fans can rattle against the case and cause all kinds of racket.
But if none of that solves your problem, you can try lubricating the fan's bearings with
a couple drops of machine oil, assuming the fan isn't sealed.
As a last resort, just replace the fan. You don't need to spend much money to get one that'll actually stay quiet.
Now, let's move on and talk about what you should do if you need to take a PC or computer
components with you on an airplane, say to a faraway land event, maybe on a mountain.
Is this something that should cause you concern? Well, in terms of getting through security or a baggage screening, you shouldn't have
too many problems. The main electronic item that you can't put in your checked baggage these days is a loose
lithium battery. These batteries can be a fire hazard.
And fires have been the cause of many infamous plane crashes, whether it's from damage to
the aircraft itself or incapacitation of the pilots.
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,
hopefully. But the average desktop PC shouldn't have a lithium battery, so you shouldn't have issues
at security. The bigger thing to keep in mind is that heavy parts, especially graphics cards, can get
jostled around in flight, so you might want to take those out and pack them separately.
And yes, you can take an AIO water cooler through as well, despite the restriction on
liquids. This is special liquid. With big-name game titles asking for more and more VRAM these days, especially if you're
playing at higher resolutions or settings, we often see people ask if they can add more
VRAM to their graphics card. In short, the answer is unfortunately no, you can't even download it.
VRAM on modern graphics cards is soldered on and not expandable.
Modern VRAM has to be rather tightly integrated with the GPU itself due to how quickly data
flows between them, meaning that expandable memory would likely sacrifice performance
and reliability. Although a few cards that actually had slots for additional VRAM existed in the fairly
distant past, trying to jury-rig additional VRAM modules under your card these days with
a soldering iron probably won't work and could even end up breaking your expensive
card. If you're hitting VRAM limits, turn down your settings and play at a lower resolution.
And if you're in the market for a new card, make sure that you're picking one that has
enough VRAM for the games you want to play. What are some of your simple questions you're afraid to ask?
