Ok, here are his stats.
He is running a generic case, with a generic 300W PSU.
I think his mobo is a Soltek.
He is using no thermal paste (I am going to send him some), just the patch of crud that comes default with the cpu. His Heat sink is a Chrome Orb, (which I suspect may not be fitted ideally). He doesn?t want to take the side panels of his case.
I think a Globalwin Fop 32 or 38 (damn noisy beast) may be a good investment for him.
The main reason I asked the question was because I had seen people talking about 90C being an ok temperature to run at, because they had seen it on the AMD site. It struck me that this was more likely to be an absolute maximum (under extreme condition, for short times), rather than an acceptable temperature to idle at.
