Hi, I have a P4 3Ghz with standard CPU fan, 1Gb Ram, 2 x 40G hard disks all in a Cooler Master Cavalier case. The trouble i have that the fan noise is really anoying. It runs at nearly 4000rpm which is too much but the chip is about 50 celsius so i'm not surprised. Can anyone reccommend to me a CPU fan that is quiet and will cool my chip better so that in runs a lower temperature and speed. Is there anything else i can do? Thanks for any help.
