Does a clean PC run better than one with a lot of dust in it?

I am not a tech person, but I cleaned out my secondhand PC today, and it took hours with the sheer amount of dust accumulation. The fans were nearly overloaded with it!!

Does a clean PC run better / faster than one filled with dust? Or is it more a matter of keeping the fans running easily? Or something else…? Idk, maybe I imagined it, but it seemed to boot much faster after cleaning. Could be wishful thinking!

Dust traps heat and blocks airflow, fans run worse etc. More heat means more likely the system will throttle down to keep temperatures manageable

WHOA!

Removing that nearly entire bucket of dust feels justified now! Makes me happy I wasn’t just wasting my time. Thank you!

Yeah, I too am morbidly curious

Looking into my trash, it’s more like half a bucket, the other half being crumpled paper towels.

Sadly, I only remembered to take a single one before the process started. You can see an alarming amount of dust on certain parts if you look closely.

Warning for tech-gore, maybe? Again, I’m not a tech person. The back has always been partially open. This was built by someone else, and it’s… probably not standard.

Wow that is… Magnificent! I’m glad you de-dusted it but I’d be more worried about cables becoming disconnected while you’re trying to clean it.

Glad it worked out for you though! Fingers crossed it continues to work🤗

FYI the PSU box with those black shielded power cables is meant to fit internally in the big hole at the top 🤣
I usually use compressed air to clean the dust out of my cases. If you’re feeling adventurous, you could slide that side panel off and attempt to re-home the PSU inside the case.👌🤣

SharkEatingBreakfast@sopuli.xyz on 29 Aug 20:40 next collapse

Oh, I labeled the cords & disconnected them to clean. Slid the side off to give everything a thorough shine!

Problem is: this cables connect to this big ho (which I also had to clean very very heavily).

the PSU box

Aye, forget the dust, this whole rig with the PSU hanging out is sketchy af. Also, the barely hanging expansion slot cover, waiting to short something with the slightest bump is also a nice touch.

tgxn@lemmy.tgxn.net on 29 Aug 23:36 collapse

It’s my kinda computer lol 🤣 Nothing should really short though as long as all the connectors are securely connected.

InEnduringGrowStrong@sh.itjust.works on 30 Aug 00:17 collapse

The PSU is sketch but likely fine. I’m more worried about the expansion slot cover that’s barely hanging.
I have an old pic somewhere of an old Frankenstein PC with the case cut with tin snips to fit a bigger GPU. It also had an external PSU for a while, although I did add a ground wire between the PSU and case. I’ll see if I can find it.

tgxn@lemmy.tgxn.net on 30 Aug 00:53 collapse

Yeah and I didn’t even notice before but WTH is the ATX plug doing on the outside of the case anyway 🤣

InEnduringGrowStrong@sh.itjust.works on 29 Aug 21:55 collapse

I would suggest to either remove the expansion slot cover or screw it back properly. As it is, it could probably fall and short something.

Yes if a modern computer gets too hot the CPU will throttle itself and the fans will run faster.

If the computer is on the floor try to get it off the floor at least somewhat. Set it on a box or something.

SharkEatingBreakfast@sopuli.xyz on 28 Aug 23:14 next collapse

Thanks so much! I have in on a little shelf below my desk. I’ll be cleaning it much more often now!

Anticorp@lemmy.world on 29 Aug 00:56 collapse

And a less modern PC will burn itself up, or just completely shut down as a safeguard.

fuckwit_mcbumcrumble@lemmy.dbzer0.com on 29 Aug 02:57 collapse

On top of that modern computers are essentially designed to run as fast as they possibly can while staying just under their max temperature. Especially laptops, they will regularly kiss 100c as part of turbo boost.

Your GPU has a much lower temperature limit and starts throttling way sooner than its max rated temp since they do NOT like running hot. Your CPU will tolerate it, but your GPU is far too large of a chip for this temperature fluctuations.

RightHandOfIkaros@lemmy.world on 28 Aug 23:06 next collapse

Yes, it will be able to efficiently cool itself better and therefore improve its performance.

BearOfaTime@lemm.ee on 28 Aug 23:41 next collapse

I have one computer that I can tell is dirty because the CPU and video fans run at max all the time, and the machine slows down (I’m sure it self-throttlws, I have the bios configured to be sensitive to heat).

Clean it and it’s quiet as can be, runs fine.

jbrains@sh.itjust.works on 29 Aug 00:13 next collapse

Yes.

Also a machine on fire tends to run a bit more slowly. 🔥😉

I thought it was just those fancy LEDs people put in their computers these days! Like a secret feature!

neidu2@feddit.nl on 29 Aug 00:14 next collapse

Yes, especially laptops. Dust leads to heat buildup, which is detrimental to performance.
This goes doubly so for laptops, as the cooling rarely has more than one flow “channel”. I open my laptop an clean it out once a year, as it runs somewhat hot even when perfectly clean.

echo@lemmings.world on 29 Aug 00:53 next collapse

Yes, it can make a very real difference.

Anticorp@lemmy.world on 29 Aug 00:55 next collapse

A cool PC runs better than a hot PC, and a dirty, dusty PC is a hot PC. So the answer to your question is “YES!”

dustyData@lemmy.world on 29 Aug 01:09 next collapse

An old Pentium III an extended family member had burned itself out of disrepair. The computer was used for about a decade before being forgotten, but plugged in for some other 5 years. Then they had the bright idea of using the old computer without cleaning it. It all went well for a while it boot up and otherwise was it old win7 self. Except, a couple of days later they let it on overnight. The house owner was awaken alarmed by the fumes of burning plastic and a faint trail of smoke coming from the case.

The over a decade buildup of dust had been trapping heat so bad that some old shoddy HDD power cable melted partially exposing the conducting wires. Then it short circuited and arced through the dust setting some lint on fire.

The flame was minuscule and it was controlled fast. But I would say that, it is indeed wise to clean your computers, at least once in a while.

AdNecrias@lemmy.pt on 29 Aug 09:07 next collapse

Pentium III, win7?! Do those motherboards even accept enough memory for what post vista OS slurps?

dustyData@lemmy.world on 29 Aug 11:13 collapse

Listen, that computer was manhandled and abused for almost two decades. You’d be shocked by the weird things they got it to do. Part of the hazard was all the Chinese “upgrades” it got over time.

Never underestimate the effect dust can have on airflow and cooling in general

nondescripthandle@lemmy.dbzer0.com on 29 Aug 12:43 collapse

In the old days when cases were much less designed for good air flow, in the summers I used to take the side panel right off my rig.

That_Devil_Girl@lemmy.ml on 29 Aug 08:48 next collapse

Computers need to be relatively cool to function properly.

Dust acts as a heat insulator, trapping heat inside.

Dust also clogs the cooling fans from doing their job.

Most computers have built-in features that auto throttle or even self shut-down if the heat gets too high.

More dust = more heat = more speed throttling & shutdowns.

This reminds me that I need to clean my PC,I can see cat fur in it

Siegfried@lemmy.world on 29 Aug 21:13 collapse

Half a year worth of my lovely fur ball sitting on the top of my desktop was enough to entirely block 1/4 of my CPU heatsink in a highly vemtilated room. I would have thought that it was uniformly distributing everywhere. Nope, it wasn’t.

Just open it and do a quick pick. And pet that bastard for me.

JetpackJackson@feddit.org on 29 Aug 21:37 collapse

Luckily my cats don’t sit on the PC, but I haven’t cleaned it in years and I can see a fine layer of dust and cat fur on the power supply and the drives. I’ll have to clean this weekend. And I’ll pet the cats for you :3
