Any or all of the fans in your computer could be causing the noise. The
periods of "gale force winds" suggest an overheating condition, probably of
your CPU but it could as easily be your video card. A lot of power supplies
came with single speed fans that are typically noisy. Better PSUs have speed
controlled fans that react to temperature changes and will run quiet most of
the time. If you've had the computer a while, or even if not, excessive
periods of the CPU fan running at high speed may indicate it isn't being
cooled properly. Especially if you aren't doing anything on the PC to stress
the CPU. It may indicate that the heat sink needs cleaning or reseating or
that the thermal grease has dried up and isn't conducting heat efficiently
If money is not an issue you can buy quieter replacement cooling fans for
the CPU, video card, case fan (if one is installed) and a new quieter PSU.
Gamers/overclockers forums might be the better place to get
advice/recommendations about brands etc..
