prob du jour: AMD 1200 processor unknown mobo w/ Via 400 chipset XP home voltage all shows normal. Sandra software showed a CPU temp of 170F....... box was locking up... CPU heat sink was very warm to the touch. put large floor fan to blow into open case....CPU temp doesn't drop.... put two other mobo monitoring programs on box....... temp now varies between 17C and C - no f'ing way!!!!! box is currently running Prime 95, and also running a DVD/movie and the temp sensing still bounces around......17C then 35C then to 55C all within 20 seconds, then will drop to a reported 17C again- while the CPU is pegged at 100%9and with side of case closed.) any ideas??? I can't swap out any hardware to test. hard drive temp @ 31-35C seems to be accurate.. but CPU temp is all over the place with any seeming rhyme nor reason. ( and the box isn't locking up under a heavy strain.) |
Also Get some Artic Silver 5, it will help aid in better heat flow from the CPU to the Heat Sink and should drop your temp even more. |

BIOS only reports a "system" temp of 30C I didn't remove the heatsink because it's an AMD and it doesn't seem to be overheating anymore..... I reset the all BIOS info in the beginning my main Q now is- why the big variety in temp reads.... from 29 to 45, and then from 45 to 25, all withing 20-30 seconds. (it's an syntax mobo BTW) |
IIRC AMD says thermal paste is verboten / voids the warranty. |

no not use software to figure out what your CPU temp is. use the bios. as you can tell they are not accurate. USE THE BIOS to tell what the CPU temp..... not the system temp. thats not as important the reason iasked if the heatsink was taken off is. alot of people put the heatsink on backwards. and end up frying the chip.. |
Ditto. My 1.2 GHz Intel Dell laptop had a heat problem that was solved using Artic Silver 5. It had thermal conductive tape which didn't hold up. Read and follow the instructions to the T. Also look at your processor load. Running FEA on mine really heats things up as processor is loaded 100% for hours on end. It is quite the room heater. |
As long as you use it sparingly, you will have no problems with Artic Silver. Follow the directions and you will be just fine. AMD has to say that to protect themselves from the many idiots who don't follow directions and lack common sense. |

heat sink is aftermarket cheapie the 'system temp' is the ONLY reading the BIOS will give me. I'm trying to figure out what would cause the wild fluctuations in reported CPU temp....... I put the side panel back on the case and pegged the CPU at 100% and it didn't change the reported temp, nor did the machine lock up.... I'm confusicated. 
|
Mobo monitor is INTEL, the board is AMD ( i tried it anyway )I have 2 different monitoring programs running now. 1 bounces from 29C to 44C back to 29 in 5 seconds ( under 100% CPU load) the second one is staying at 27-29C (under 100% CPU load), but will pop up to 42C on occasion. |

aha!!! that's the Mobo program I used to use...... unfortunately, it just locked this box up bigger'n shit.  I'm gonna call it a flaky mobo and as long as it stays up, we'll leave it alone.

The older socket A heat sensors weren't particularly accurate, they could be upto +/- 10C due to them not actually touching the core. Most of the time people who actually needed to know the core temperature used an external diode to read it rather then the built in one in the center of the socket. By what you posted, your chip is a 1200mhz original Athlon, correct?... If so, those chips just ran hot period. I had a 1300 a long time ago and despite having a top uality heatsink and 8 case fans, I wasn't comfortable with the chip running 55-60C load. The 1200 I traded to wasn't much better. It ran about 55C load consistantly and when idle went WAY down in temp, using resting idle about 6-8 degrees above ambient temp. This whole situation could be made worse if someone decided to overclock it for you. |
