Epox 4PDA2+ rev 2.0
P4 2.8
Phoenix 12/25/03 bios

Zalman CNPS7000Cu cooler
Antec trupower 430 w psu

Standard ram settings, no OC

I happen to notice on boot that my CPU temp is hovering around 65 C. I
never check temps so I don't know how long this has been the case.
This machine had typically run CPU temps of ~40 C. Stable, runs
normally, always has.

The cooler feels about the same as I remember--barely warm. It can't
be idling at ~65 C unless the arctic silver interface has somehow
deteriorated and heat transfer has been compromised. I've not yet
pulled the Zalman for inspection (nightmare installation), but screws
are torqued.

USDM shows no meaningful temp increase above a bouncing 65 C while
forcing 100% CPU usage with prime95 + NAV scan. Coupled with the fact
that this mobo is notorious for dodgy sensors, I'm guessing that the
sensors have completely failed and producing nonsense, and that actual
operational temps are probably normal. System temp remains stable at
~35 C. Comments? Oh yes, V I/O is ~ 2.75V, all others normal.
Darned if I can find what normal V I/O is supposed to be.

ambient room temperature has remained the same?

Yes--I should have specified that the ambient temp has been a fairly
constant 70 F.

Additional note: Using CPU Burn-in v 1.0, USDM shows the temp
occasional peaking at 100 C.
