Afternoon all,

Just after some thoughts, my mates PC keeps switching off. I told him to install Spped fan to monitor temps as i was sure the CPU was over heating.

It was it was at about 80c @ idle! Speed fan also shows a temp of around 70c in 'aux' What is this? is it the power supply? MOBO? any ideas?

Anyway i instructed him to take the side panel off (he knows nothing about PC's) and he told me the heatsink on the CPU was full of dust etc.. He hoovered it out and the CPU temp went down by about 15c at idle but still shuts down under load.

Im off to see him tonight, my thoughts so far are either the CPU thermal compound is not right, i shall re apply it. Or the power unit is knackered.

Whats your thoughts? Sorry i dont know the spec the PC is about 3 or 4 years old and my mate paid someone about a year ago to upgrade it, since then he has had the shut down problem.

Thanks guys

Jay
 
Cheers Freddie, gonna strip it down and give it a clean hoefully that should sort the problem out. From what i have read Aux could mean anything from power supply, Mobo to a false value reading.

The sink can only hold so much heat. If dust means its insulated then the heat will just keep building

Tell him this is why he should stop smoking, its killing his computer
