platform for number crunching

[Orna Agmon Ben-Yehuda]

Hi Shimon

1. I have a feeling you will anyway need to improve the fans/replace the box
to a larger one (much more effective than air conditioning).

2. I suggest asking in gamers forums, those who overclock their machines.
However, the first thing they do is open the box's sides (for better air
flow) and get a stronger fan.

3. Check the thermal control. You may wish to enable some thermal control
options for the processor you already have. Alternatively, sometimes the
thermal capping ("stop if you get too hot") is not well adjusted, and the
CPU shuts down when it can actually work in these temperatures (40 something
should work fine). Had this problem around the year 2000 with AMD 1300MHz
processors, and bios updating solved the problem.
