70 Degrees bah, check this out!
My neighbour asked me to come round to look at his computer as it kept freezing in windows whenever he tried to do anything that was hard on the processor.
After showing me it locking up by doing a virus scan I hit the reset button.
When bios flashed up I just happened to notice that his unknown cheapo brand Celeron 2.93 was running a touch hot at 103 Celcius!!! I thought no way, that mother's fried. I asked him how long it's been freezing, he said "oh a few weeks now" lol.
Cleaned it out with a hoover, took off the heatsink and applied some artic silver and reseated, now sitting at 29C Idle and 38C full load, much better, from now on he cleans it out every month (coal fire)
I'll have to suggest that tights idea to him for the vents on the side of the case.
