CaseCPU Temps

[Guest]

Archived from groups: alt.comp.hardware.overclocking.amd (More info?)

Hi folks,
I just put together a new box. AMD XP3000 CPU on an Abit KV-7 board.
The CPU temps are running between 45 C and 55 C, the case temps are
running between 55 C and 65 C. I can't think that this is normal. I've
never seen the case temps run higher than the CPU temps. This ten
degree spread exists even on a cold start. Could something be wrong
with the sensors? Any input would be appreciated. Thanks, Axel.

And you are reading these temps where? In the BIOS? Using a monitor
program? If so which one?

I'm using MBM 5. Also, Lavalys "Everest". Both show the same
readings.

Please don't top post. I've never used Everest, but I've often seen
MBM 5 assign the wrong readings to the indicated sensors. This can be
changed to the correct sensors by reassigning them.

In the meantime figure the highest temp is the cpu, the next highest
is the motherboard temp. They're both on the high side. If you take off
the side of the case and they drop you need better case cooling <
more/better fans >. What's the room temp? Cooler room means cooler air
going into the case.

Its virtually impossible for the case temp to be higher than the CPU temp.
(Unless you have a massively overclocked GF6800Ulta video card and no
airflow!).

The two possible causes for what you see are either (a) the sensor are the
wrong way around. This is quite common. Or (b) the sensors are
miscalibrated. This is quite common too.

To check which it is, load the CPU up with something like toast.exe and
watch the temps. The one that rises fastest is the CPU temp. The case temp
will always move more slowly as it takes longer for the case to heat up than
it does for the CPU.

Having determined what the cause of the problem is (a) or (b), you can then
either swap them around in MBM or whatever. Or forget about it ;-)

I went into the health section of my bios and saw a reading named "PWM
temperatures." This reading is the same one that is reported as case
temp by the sensor in MBM 5. However, if I start a program that pegs
the CPU, it is this sensor that rises faster than the reported CPU
sensor. What is the PWM temp? Thanks, Axel.

I have never heard the expression before. My gut reaction is that it might
stand for Power Management ? I know Abit have done some stuff on cooling the
mosfets etc with their OTES system. Maybe they have temperature sensors on
the mosfets. I dunno.

PWM = Pulse Width Modulator - or Voltage regulator - it's showing the
temperature of the MOSFETs. They are tough little cookies and damage
sets in at about 120C. I stuck some of those little copper RAM
heat-sinks on mine and it keeps them at about 45C under full load.
