How to shut your PC up?

Hey guys -

Have any of you any tips for getting a PC to run quieter? I have my old computer running as a media center, but it's quite annoying watching quiet bits of a movie as there's a computer cranking away in the corner the entire time fairly loudly.

I've tried turning the fans down but it hasn't done too much - the whole thing is cheap and cheerful as and if I need to buy lots of new stuff like silent PSUs etc, might as well just get a laptop to do the media instead.

I read about some insulation stuff you can put inside your case - anyone had any experience with that, does it work? Any other ideas I could try? I'm down to putting it in a box.

Bigger fans tend to be quieter (possibly because you don't need to run them at high speeds).

If the cleaning fans and vents doesn't fix then:
Replace the PSU with a good quiet one.
Replace the stock fans with aftermarket silent running ones - cpu/gpu/case.
Run your own GPU fan profile (if it's one of those always on 50% ones).
In extreme cases for ultra nerds you can go for the hidden cable management.

bigger fans, but as a media center you dont really need them as much so one 120mm exhaust would do.
check hard drives to see if there makin alot of noise, if so, replace...not alot you can do with a loud HDD.
check PSU, makin alot of noise, you CAN replace the fan but just gotta be careful with it, if you cbf any odd PSU with a 120mm fan are generally quiet.

Thanks guys, I'll try cleaning the fans this evening. The case is like 12 years old, it's only got a 60mm so I might turn that off and watch the temps - it's only playing movies!

You can get a 120mm for about 15$ bru, a 20cm's around 30 and almost silent in my box. Tin snips and a drill?

Old fan bearings are probably the cause, so yeah I'd say get a new one

can you get like rubber washers or something. Sound is caused by vibrations. Getting a aftermarket fan could help, there not that expensive.

You could try cover up all the non important parts of the case with something like



or foam.

Yeah, covering exhaust holes with something designed to keep heat inside a house is an amazing idea.

But the washers point is true, if you suspend your hard drives with rubber and place rubber washers under steel on steel screws etc, combined with low RPM fans you'll find case noise will practically vanish. Most silent PCs are setup with low RPM fans or no fans and rubber mounts to try and remove any vibration noise. My old PC6070 was setup like that out of the box.

What I did was buy a WDTV unit, then put the machine in another room
I actually used an old slimline workstation so it was pretty quite anyway.

If you wanted to be really ghetto, make a box out of MDF and place it over the entire case. Putting holes in the front at the bottom, and a hole at the back right at the top - big enough to provide airflow (keep an eye on temps for the first hour or so).

I'm sure it works but I'm dubious about how effective sound deadener is for PCs, particullarly if its the external fans/air flow noise.

If its fan noise though, just rip out the 60mm, and custom mount a 120 or larger silent fan at 7V, and fit a passive CPU cooler + GPU cooler. All depends on budget though.

Submerge your PC in mineral water and contain it!
You could also get larger fans aswell... they require more power but they pump out more air, are much quieter and don't shake as much as smaller, faster fans.

My solution is 4 regular fans, the rooms aircon, and a G35 to block out the noise.

On inspection it is just the case fan that sounds like a jet, so I'll get a bigger newer quieter one and see how tolerable that is

Thanks for the input folks
