I'd suggest doing a visual inspection. Make sure all fans are not blocked by cables, are spinning. If that looks normal pull the CPU heat sinks and make sure they have good coverage with the heat sink goo, but not so much that it leaks over the edge of the chip. When you put the heat sink back on make sure the heat sink mount works as intended, especially on the (mostly intel?) 4 post system where an unclicked post can result in unevent heat sink pressure.
Be careful, fans moving != spinning. I've seen some that just vibrate enough to look like they are spinning at a casual glance and are actually not moving much air and are contributing a fair bit of heat to the system (I.e. very hot to the touch). If that looks normal then I'd start swapping parts till you find the heat sensitive one. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
