My response was purely a subjective one, comparing your cooling
performance to the average user. You are correct, that you aren't even
close to frying anything. In fact, most processors could run a lot
hotter than they do. The thing is, you have one of the lower power
dissipation processors in the Pentium 4 line. I won't bother to look it
up again, but it should be in the 58 Watt max power area, whereas a
top of the line Pentium can be 85 Watts or so. Based on the low
dissipation, I was expecting a lower temperature to exist. If you
have a higher temperature, it is a good idea to add a bit of case
cooling, so the drives don't run too hot. Based on your description of
the fans, it sounds like you have that covered, and I wouldn't suggest
adding any more.
On the processor heatsink, I like to use a little Arctic Silver
(AS3), instead of the "black stuff" that Intel uses, but each
person has their own preferences. The Intel stuff looks to be good
for one use, before it gets scratched and scuffed on the retail
heatsink/fan. If you frequently remove the HSF, keeping a tube of
something handy is a good idea.
If anything, a neglected area of concern is the hard disk temperature.
Having a high case temperature can shorten the drive life. IBM publishes
a curve of allowed temperature versus humidity for a given product
life, and if you run 60 percent humidity in the room, you can get
pretty close to the curve. (If you have air conditioning, you won't
get there, but a house without air conditioning will get there in
the summer.) I guess as a result, I like to see the temperatures
kept down. You didn't state the case temperature you've got, and
it is good to state both case and CPU temperatures, so they can
both be considered.
I think in one of their new computers, Apple used an air temperature
of 50C as the trigger point for one of the cooling fans. They did
that to try to keep the product quiet. Since the case is divided into
separate sections, not all the components suffer the same conditions.
So, by design, it is possible to subject some of the components to higher
ambient temperatures without a problem.

What you aren't taking into account, is that at a given CPU MHz number,
there are a number of different SSPEC processors released. When new ones
come out, sometimes they change the CPUID, because they are actually
using a different mask or process revision. It is still possible the
beta BIOS will solve your problem. If you are worried about the
possibility of borking the BIOS by flashing, there is a recipe using
CTMC, where you extract a 2KB microcode from one BIOS and have CTMC
put the microcode in a cache area of the BIOS chip. This is safer than
flashing the BIOS, because the area is volatile and gets updated every
time a different CPUID processor is inserted in the 478 pin socket.
Asus cannot release a motherboard if that cache area cannot be updated
reliably, hence fooling with the area is "safer".
I analysed a similar motherboard P4S533-E BIOS a while back, and
detected that indeed the beta BIOS for that particular motherboard had
one extra CPUID in it. There is a good possibility the same situation
exists for your board. This is the thread:
