This is when I realized that the Q9300 CPU could be too big a processor for the fan that I have installed. The fan that I have, is: http://www.dynatron-corp.com/products/cpucooler/cpucooler_model.asp?id=165 So, it looks like it's not really made for a Q9300 CPU, although their specs say it is
that fan says its for up to 135 watt CPUs, I don't think a q9300 is anywhere near that, so unless that heatsink fan is grossly under its speced capability, I dont think thats a problem. Yeah, the Q9300 is 95W max, and thats with all 4 cores running heavy math...
HOWEVER. Intel desktop boards generally have a passive heatsink on the northbridge and expect the downdraft from a conventional CPU fan to cool said northbridge. your 1U configuration might not be moving enough air past that northbridge. I know on my DG33TL in a desktop minitower, the G33 northbridge runs pretty hot, and I had to arrange for some extra airflow past it since I used a 'tower cooler' which blew the air sideways rather than down.
I still think running four instances of mprime (from www.mersenne.org) each bound to a different cpu affinity (-a0, -a1, -a2, -a3) and running the 'torture test' overnight will tell you a lot. do this with xen disabled, just the base system running at init 3. any sort of computational or memory timing related glitch will show up as a numeric error and be logged by the program.
