Making an old computer quieter

Solution 1:

SilentPCReview, which Strop mentioned above, maintains an occasionally-updated list of their recommended case fans. Obviously you can only do so much with 80 mm fans.

They also have a list of recommended heatsinks, but I've found that you need to do more of your own research in this area, simply because there are so many brands and models to choose from for any given socket. I generally look through all the cheap, well-rated tower heatsinks with copper heatpipes and aluminum plates. This Newegg SERP may be relevant.

Normally one of the smaller Xigmatek models is an practical if unassuming choice, but being on socket 754 is somewhat limiting. A more traditional model, with the fan blowing down, may be fine since your cooling needs aren't incredibly high. The Thermaltake A4017-01 looks particularly cheap, quiet, and well-rated, and it's AMD-only, which may ease installation.

Solution 2:

Coding Horror has an awsome post on how to make a PC quieter

Which includes

• Minimize the number of fans in your system
• Control the speed of your fans
• Dampen your hard drive
• Use noise-reduction materials.

Starting with the right parts helps a lot.

Solution 3:

Get some insulating (looks like sponge with hills and valleys) material and put it inside the case. Works better than any cpu replacement. Cheaper too.
