I agree.
I just built a system based on a Chaintech MB with a GlobalWin CPU Fan/HSF.
The idle temp on that one was about 37c.

The CV is 1.78. (This comes from BIOS, not ASUS probe.) I can pop it down a
bit and see what happens.

I'll look into that. I'll also throw the heatsink around and see if I can
make it fit better.
Incidentally, I turned the fan around last night so it blew air off the core
instead of at it. The system still became unstable, but it didn't seem to
reach that point so quickly.
There is no doubt in my mind that one of the problems is airflow. There is a
dead-zone in the case toward the upper-front. The air the fans push through
the case would never reach the CD drives, the RAM, the CPU, or the HDD.
Incidentally, this is where all the wires are as well.
I'm a little unclear, however, on how to relieve the problem up there,
though ... short of drilling a hole and attaching another fan.
Plus, if I take the side-panels off, the system remains stable. This is the
most definitive result I've seen yet.
I also wonder if the case is a problem, too. It's a mini-tower. I imagine
one could run an Athlon XP 1800+ in a mini-tower, but this is one thing
that's different between this system and the Chaintech system I built.
Here are some pictures I took last night.

Well, the fans are spinning, if that's what you mean. There is air being
pulled into and out of the case. The front panel barely lets in any air. I
think I can safely say that if I leave the front panel off and attach the
two side panels, the system will become unstable but only after quite a bit
of time.
The fans are not the same specs as yours however.
