OCPlus have a guide to making a variable speed fan from a temp-sensing one. Pretty simple stuff.. the advantage of course is that you can choose the fan speed and hence the noise it makes, as suitable for how hard the PC is working at the time. Surfing the web: quiet. Playing a game: loud. More ideas along these lines from our archives: voltage reduction to slow noisy fans, using an automotive rheostat to control a lot of fans at once and a thermal control circuit to speed them up automatically when things get hot. There are commercial products to control fan speed too, from the (probably only in Japan) ST Fan Controller to the impressive-looking PCMods Rheobus and the automatic Digidoc 5.
The SB Audigy may not be as new as originally thought. I'm sure we heard something about this when the Audigy first came out, but it went all quiet again.. hmm.
TheInq are reporting on a strange statement by an IBM person about some of their HDD products.. that they shouldn't be powered more than 8 hours a day..? Thanks ScarifieR.
