Hi all, hope someone might be able to help here! I've got a problem with my pc and i dunno wats gone wrong! My cpu fan speed will NOT go above 2600rpm!! My PC is NOT clocked! Specs are as follows: CPU: Celeron 2.8ghz Memory: 512mb M/B: Gigabyte 81915p-g M/B software: Easytune5( Only used to monitor hardware settings) O/S: XP Pro Oh yes and Artic silver paste was used when pc used together. It used to rev up and down until recently when i noticed that the pc kept beeping away and then i checked the temp and seen it was 72C!!! The fan speed showed as around 2584rpm. I've since been watching my pc and noticed that when the pc is idle the speed stays around the same and the temp is around 34-40. I've cleaned out all the dust from the fan and no improvement. I've taken of the case cover to see if it would be any better but nothing!! I have not changed anything on my pc since i've had it so this is a bit of a mystery. Most interesting of all is that i only run 1 program at a time so its not like my pc may be overloaded!!
