Sorry for the bump, but is it possible that a cable is loose/unconnected, causing the fan not to read the cpu temp thus, running at full speed all the time?
I had an IDE hdd but no IDE cable, so I went to a computer shop to get an IDE cable and for him to plug in the hdd for me. Is it possible he made something go loose? I believe the noise wasn't there before I went to the shop
Thanks everyone
