How do i make my pc quieter? - Page 3

post #21 of 33
My 690 used to make a rattling noise until I took out all the screws that line the edge of the 5.25" drive bays. I noticed a few of them were stripped, probably from the vibration of the case. Once I took them out, the rattling stopped. They serve no purpose, so it's worth a shot.


Edit: Also, the fan grill on the side panel causes a lot of whistling, more so than any other on the case. I never got around to cutting it out with the rest when I was modding my case, but I have the side fan (only have one on the side panel because the TRUE is a beast) hooked up to my fan controller and keep it on the lowest setting when I'm not gaming. If I bump the speed up at all the fan sounds ridiculously loud. If you're going to cut the side fan grills out, pick up a new grill that will let more air in.

The side panels on the 690 are also extremely flimsy. It's worth putting some foam on the fan side panel to reduce vibration.

If you want cheap and effective, and if the noise is air noise, get some 800 grit sandpaper and sand the fan blades super smooth, especially the leading edges. Also sanding the inside of the shroud around the fan helps. This made an Arctic freezer 7 fan go from quiet to nearly silent, and also made the Thermaltake volcano 12 3 blade fan zip tied to my cpu cooler much more tolerable at high speeds. It really gets rid of the higher pitched obnoxious hairdrier/vacuum cleaner type noises.

I put electrical tape where the fan touches any metal. Stops most vibrations although it isnt exactly sexy. You can however trim it so you cant see it that well.

you can also make your fans run from 12v to 5v or 7v

I'm with the others.... dremel out your old fan grills and replace them with rounded ones, less chance of anything getting stuck into them, but with less noise due to turbulence.

Also, fan silencers. In the absence of an actual "kit" cut your own out of an old bike innertube or similar gasket-like material

thanks for the input guys, i will look into cutting the fan grills maybe just leaving the grills out completely. I found that the only sound that is coming from my case is the fans, i don't feel much vibration anywhere and the fan that i think is making the most noise is either the cpu or exhaust fans.

I read a thread about some tape from hardware stores i was thinking of giving that a try.
First, you need to develop appropriate expectations. You can make a PC powerful, cheap and quiet - but you only pick 2 and you seem to prefer the first 2.

Just how quiet do you need it and what are you willing to pay?

The most obvious thing is that you said your case has 3 fan mounts, but you are only using 2 of them. You can probably add a 3rd fan and reduce the speed of all your fans to see similar air flow and a lot less noise.

The other thing is that the "electrical tape" and similar solutions are really designed to reduce sympathetic vibration noise - which you may have, but my guess is that you can't hear it over your high speed fans.

Try to run a few 120mm fans at 1000-1500 RPM and see if that does not help a lot.

It is possible to achieve virtual silence on a high end gaming system, but it requires a lot of planning, knowledge and money. As expensive as it is to do it right, trying to retro fit a noisy system can end up being even worse.
