system hotter than cpu

ok whats the deal he

There is a problem with your case ventilation. Are there any fans in it?
The two hard disks plus the 9800 Pro dissipate a lot of heat that has to be
extracted. You should have one or two fans blowing into the case and one on
top of the psu fan(s) extracting the hot air from the case.

My sysoft sandra confuses the system and cpu readings - ie they're swapped.
Could be your problem. Does the system temp rise quickly from cold? This
might indicate same thing happening.

This *is* the problem. It is against the laws of Physics for the system
temp to be higher than the CPU temp. (Unless he's using a pelt, or has a
heater in the case.... which I doubt somehow.)

Actually, some boards have the system sensor where it can be hotter than
the CPU sensor. The ASrock K7S8X series is one such board. I think the
system sensor is actually on the northbridge although I didn't check for
sure. At idle, running Athcool, the cpu temp is about 1-2C lower than the
reported system temp. Under load that changes of course with the cpu temp
going 10C over system temp. But I would agree with you if the system had
an open sensor not close to something hot.

Fair point. If you site the case sensor next to another source of heat,
then its possible. (I did say "unless you have heater in the case".)

The simple law of thermodynamics is that heat flows fom hot things to cooler
things. You can't have something *being* heated, hotter than the thing
heating it. Its just plain impossible.

As an aside, what complete *stupid* places manufactures put the system temp
thermistors in. On the Abit nf7-s its right under the CPU hs!!!! How nutty
is that? Not so much the system temperature, more the "CPU Exhaust
Temperature".

i have 3 case fans blowing in (one in front bottom 2 in back and the
case side off with these temps

My system and cpu temperature was hotter with the side off. My system
and cpu temperature was hotter with the fans blowing in instead of out.
My coolest temp was achieved with all cooling fans pulling hot air out
of the case. My core voltage is set at 1.9V and my fsb is set at 212 and
my idle temp on the cpu is 47C with fully loaded usually going to 56 or
so.

I dropped 2 degrees f by having the case removed on back side of MB. the
other side left on with a fan attached and blowing out. tends to suck the
cooler air in and around better that way I guess.

Assuming these temps are being reported correctly, can you locate the
thermistor that measures the case temp?

I have a similar situation when my PC is idling but that is due to the fact
that my mobo thermistor is situated directly in the warm exhaust from the
graphics card fan.
