That's a good point. I have no way of knowing whether there was a change of policy. If there was, it was nothing I did - that kind of technicality is out of my league. > Don't you have another hardware monitoring chip on the board? On an > Asus M2N-E, I'd really guess so.

IT8716 reports temp1 as 42C, though I'm not sure what it relates to. temp2, which I'm pretty sure is the MB, has remained around 34C throughout. THRM seems permanently stuck on 40C. It never ever changes. > Also, what temperature does the BIOS report? That would be an > interesting comparison point. I thought of that, but concluded that there wasn't much point in looking, since the machine would be effectively idle and it does cool down very quickly after any load stops. shutting down and rebooting takes time.

By 'similar' I meant the same except theirs is the SLI version. - Richard -- Richard Kimber http://www.psr.keele.ac.uk/
