The 90nm Venice and San Diego cores are very cool running chips. My
overclocked, overvolted Venice at 2.61GHz runs around 28C idle, and 42C max
load. Temperatures of the extreme you mention almost definitely indicate one
of two things:
1. Improper reporting of the temperature (try closing whatever you're using
and use Speedfan)
2. Improper installation of the heatsink/fan, or somehow significantly
obstructed case airflow.
Sometimes you can have a situation with a particular BIOS release having
incorrect temperature readings, so I would check that you are running the
latest BIOS. If you are, you might try downgrading one revision.
If I were you, I would start an encode, then feel how hot the heatsink is
after a while of running.

Subject: [H] AMD64 Heat Issues
I recently put together a new system with an AMD64 3700+ San Diego core
cpu.
One of the reasons I build a new system was that I was having heat issues
with my Athlon XP 3200+. The mobo design of the Gigabyte GA-7NNXP does not
leave many options for larger hsf installation. I was hoping that the
newer,
cooler running AMD64 would eliminate this problem. I thought it had.
Initial
temps were in the 25-30 degree C range, with temps raising to the mid to
high 30 degree range under load and the low 40s under heavier load. I
recently did a longer video recode and the alarm for 60 degrees C started
sounding! (I am running the stock cooler provided with the retail AMD chip
and monitoring the temperature with the included EasyTune 5 utility).
