[Klug-general] How to solve a noisy computer

[nic dan]

Try underclocking/undervolting to save power/thus heat

Fans get noisier as they gather dust/bearings wear

Changing case fans to quieter ones is fairly easy, though utilities to slow the fans or settings in bios can improve things

Also usable for cpu fans

In my opinion liquid cooling should be avoided, as though it's quiet, many people have trashed PSUs and mobos when they leaked


Also quiet power supplies are available though more expensive

It might be worth considering a different approach

My Computer is far too noisy, and I'd like to cut the noise down.
Most of noise seams to be coming from the PSU and the Main AMD chip fan.
Other than replacing what the best thing to do.

a> Replace the PSU with a quieter one. (easy job)b> Replace the main heat sync, looks easy but dangerous.
If I'm going to replace them what with, I want something quite and not too expensive. 

The computer has 4 fans, 2 case fans which are very quite from what I can work out, and CPU and PSU fans.
Oh its a AMD64 dual Core Front room PC.....
Suggestions?

Peter.
