Case\CPU Temps
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. |

I'm using MBM 5. Also, Lavalys "Everest". Both show the same
readings. On Wed, 6 Oct 2004 20:17:41 -0700, Bill wrote: In article , says... Hi folks, I just put together a new box. AMD XP3000 CPU on an Abit KV-7 board.

Using a monitor program? If so which one? Bill |

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 ;-) Chip |

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.

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. Chip On Thu, 7 Oct 2004 11:30:34 +0100, "Chip" wrote: "Axel Beck" wrote in message . .. Hi folks, I just put together a new box. AMD XP3000 CPU on an Abit KV-7 board.

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. |
