Although my PC isn't obtrusive when a film is playing, I was thinking of trying to quieten it down a bit. The CPU fan seems very noisy due to its high speed, but case fans and the PSU don't seem to make much noise at all. I was looking at the 'quiet PC' stuff, and PSUs are very expensive (£45), and after having just taken mine apart, all I can see is a 4inch case fan. Admitted, the PSU itself might generate some noise, but surely the fan makes the most? So, if I replace the PSU fan with a 'quiet' one, shouldn't that be enough? Also, in peoples opinions, how would you list the noisiest components in order of noisiest? i.e. : CPU PSU Case fan DVD drive Hard drive I haven't tried them all myself, so that is just guess work. How much noise does a hard drive make for instance? Also, who has significantly reduced the noise in their htpcs without spending loads of money on doing it? My desktop PC (1.2ghz TBird) generates about 55db of noise and it only has one case fan, CPU fan and a PSU with a fan, as well as a HD and a DVD (not accessing at the time). The reading was taken from about midway up the tower case and half a meter away. Cheers. Gary.
