And btw: is it normal that the chipset fan is running at 8000-8500

controlled dynamically. And if the cooler wasn't properly attached, the
chipset might me saying to the cooler "I'm too hot! Run faster! Faster!"

There is a known problem with these fans. After a while they may start to
die!
Asus will replace them for free with a larger newer version. Mine arrived in
the post this morning.
I cannot say yet if they run at the same high speed or if they make as much
noise as the original ones.

I went to the Asus support website and sent an email telling them that my
fan had started to run slower.
They emailed me back an order form to fill in so they could supply me with a
new fan for free.
I suggest that you do the same so that when you fan starts to die "and it
will" you will have a spare ready to put in.

I have just fitted the new fan and it has made the PC a whole lot quieter.
The new HS+fan are bigger than the originals and because of this the fan
runs a lot slower. Before the fan was the loudest thing on my set up
Mine is now going at just under 5000rpm. Much better that the 8000+rpm
screaming piece of crap I took out.

What about Power Supply?

I'm guessing it's one of 3 things. MB (or config), CPU, OS. And note that
that's a guess.

Mine is an Antec SmartPower SP400 400W PSU. I think it should be
adequate. On the other hand. 12V reads as 11.7V, 5V reads as 4.92V, 3.3V
reads as 3.26V and CPU-Z, Everest and ClockGen disagrees about the Vcore.

I believe that the tolerance level is plus/minus 5% on the voltages. Your
readings seem fairly typical.

If you are running the RAM in dual channel mode, crappy RAM could be causing
problems. You might want to try it out in single channel mode. We had a
similar experience with a Socket A MoBo.

Just a thought,

Look for the CG-NVNF4 version of "clockgen" here. Good
for verifying clock frequencies, and discovering your
RAM clock is way faster than you thought When your
FSB is 225, your RAM is 12.5% faster than the BIOS
reading says it is (and no, I don't have the board, just
read about it).

You're saying the BIOS is showing you one thing, while setting it to
something else?

Have you seen this on any other Asus boards/BIOSes?

references would be very helpful. We have an ongoing investigation into
AMD/Asus crash reports and any information I can find would be good.
