My current spec is.
Intel i5 2500K
Asus P8P67 LE Motherboard
Zalman CNPS9900MAX CPU cooler.
The CPU idle temp used to be around 24-25ºC when the CPU fans and chassis fans are on standard.
However the CPU temperature has crept up to 30-32ºC when idle and turning the all the fans on to full speed has zero effect on the temperature at all where usually it would make quite a difference.
I have noticed the CPU temperatures are not reading steady. I watched my computer idle for 5 mins with the temp being updated every second. I would see huge jumps in the temp reading at times. It for example the readings would say 30, 30, 30, 22, 38, 32, 30, 30, 30, 38, 26, 30
I have never witnessed this before, and when the temp changes I noted the CPU and it was still hanging around the 1-2% in use.
I turned all the fans on full speed, again no change in the CPU temp (Motherboard temp dropped a degree or 2) and I witnessed exactly the same fluctuation.
I have blown the computer out with an air compressor, put a vacume cleaner in to get rid of the dust.
Does any one have ideas what could be causing it as I think it is causing my computer to bluescreen and also randomly turn off. (when it turns off there is no report in the events as to why it turned off)
