Recording near the computer is quite noisy: how can I get rid of the fan(s) noises?

From N-Track Wiki

One quick and dirty solution to the problem is to put the computer case in another room, make a small hole in the wall and make the cables pass through this hole.

There are companies today that sell low noise PCs for audio recording, although they tend to be somewhat pricey.

Alternatively you can replace your computer stock components with low-noise equivalents.

The most commond causes of noise are CPU fans, power supply, graphic card fans, hard disk vibrations transmitted to the case etc.
