This common mistake is silently killing your PC

Our PCs often cost thousands of dollars, and yet, we don’t always treat them with enough respect. Something many of us are guilty of can be a silent PC killer in more ways than one, and it has everything to do with where your PC lives on a daily basis.

Where your PC lives can become a major problem

One of the most common ways you might accidentally damage your PC is by keeping it on carpet. Desktop manufacturers (such as Dell and Lenovo) and tech experts warn against it, but many people swear by it anyway.

You need ample airflow to consistently cool your components, especially if you own a powerful GPU, a high-end CPU, or one of the fastest SSDs. All of those parts generate a lot of heat, and if the PC can’t draw cold air in and let hot air out, they’ll eventually overheat.

Your case usually pulls in air from the bottom and the front, only for it to escape through the top and the back. Placing your PC on carpet can therefore block a critical source of ventilation, and even if there’s a bit of a gap, the carpet itself is still a problem.

Carpet is typically warmer, super-prone to collecting dust, and may cause static electricity, especially when combined with dry air. I don’t even have carpets in my home, and I still deal with static all the time just by virtue of the air being dry in the colder months; imagine how bad it gets for your PC when it comes in contact with carpeted floors.

Keeping your PC on the floor is just not great, carpet or no carpet. It’s especially problematic if you have pets, because your case will become stuffed with dog or cat hair in no time (again, I speak from experience).

But if you must keep it on the floor, at least avoid carpeting—the risks aren’t worth it.

The most common risks of keeping your PC on carpet

When I discuss this with people who keep their PC on the carpet, I often get a “but I’ve done it for years, and it’s been fine,” in response. That’s because the associated risks and issues build up slowly over time.

Limited airflow, especially to the PSU

The main risk, which is so high it can almost be treated as a given, is restricted airflow.

Carpet reduces the clearance your PC needs to pull in cool air. PC cases have “feet” that lift the PC off the ground, leaving a bit of clearance between the floor and intake vents. On a hard surface, this is fine (if still not ideal), but on carpet, the feet sink into the soft surface, with the fibers pressing up against the vents.

Your entire PC doesn’t love that, but the power supply is arguably one of the components that suffers from it the most.

These days, you’ll often mount the PSU at the bottom of the case, with the fan facing downwards. The fan pulls in cool air from underneath the PC and exhausts it out the back. But with a carpet underneath, the PSU has to spin faster and louder to get air. Worse yet, it might not get enough air, leading to overheating, efficiency loss, and potential failure.

Thermal throttling

Too much heat will eventually choke not just your PSU, but also the rest of your PC. The GPU and the CPU may downclock if the temps get too high. Overheating is also a risk for SSDs and may result in lowered performance.

Dust buildup

A PC left to sit on the floor will always gather more dust and debris than on the desk, but putting it down on carpet only amplifies that. You’ll need to clean your PC more often, and always run the risk of the fans being clogged with dust, lint, or pet hair.

Static

Static is a smaller, but real concern. It shouldn’t hurt your PC all on its own, but it will manifest itself when you interact with your PC, which is why you should always ground yourself before touching the computer.

The worst-case scenarios are less likely, but severe

I’m not going to catastrophize and tell you that your PC is toast if you don’t take it off the carpet right now, but there’s always a chance that something may go majorly wrong.

Modern PCs protect themselves against the results of overheating and dust buildup. You’re far more likely to experience thermal throttling, or in the worst-case scenario, random shutdowns, than a PC-breaking disaster. But why subject yourself to any of it in the first place?

Repeatedly running hot can shorten the lifespan of your most expensive components, including the graphics card and the processor. Problems with the PSU may eventually render your entire PC unusable.

Shutdowns and black screens are possible, but poor performance is more likely. In the long term, without addressing the issue, your PC may get noisier as fans have to work overtime to keep it cool with all the extra dust.

The good news is that all of this can easily be avoided with little to no expense on your end.

The easy fixes that don’t cost a fortune

If you’re willing to get your PC off the floor in one way or another, the good news is that it can be much less of a nuisance than you’d think.

The easiest way is to just put it up on your desk, a nearby shelf, or a side table. Alternatively, keep it on the floor if you must, but at least move it off the carpet.

If none of that is possible, put the PC on a flat board, such as a cutting board or a spare shelf panel, with enough clearance on each side to make sure that it doesn’t come in contact with the carpet.

Alternatively, if you’re willing to spend a little bit of money, there’s a lot you can do with a PC stand or PC cart. The latter can be bought for as little as $15, and its whole purpose is to elevate your computer and give it enough space to breathe.


Beyond that, if your PC is on the floor, make sure you keep it on a tight cleaning schedule. A thorough clean once every few months will keep your computer running well without a hitch, regardless of its surroundings.
