Celeron 2.6, Zalman cooler, NVidia FX, 1 PVR-350, 1 PVR-250, 1 HD
7200rpm, 1 DVD, 2 case fans, power supply with 2 fans.
The system is inside a cabinet, which has 2 fans in its back panel.

Depending on the room temperature (it gets warm in there on sunny days),
I got the following, while the system is IDLE:
When I stress the CPU (compiling takes 100% CPU time), then it can go as
This is awfully near the max temp. for this CPU (72) and this HD (55).
But it runs stable.

Modern desktop CPUs tend to be very hot these days. I've already
installed enough fans in the case and one of the best CPU coolers. Not
much more I can do. I have a desktop case, I think (bigger) tower cases
are better. Next time I will probably use a Pentium M CPU. This thermal
power, that the desktop CPUs produce, is insane. And the current case
standard ATX is not very good for this heat. Even Intel seems to become
reasonable and will base future CPUs on the Pentium M design, not the P4
