Think 42 for the mainboard is a bit high, maybe your videocard is close to the sensor? My asus P2B with overclocked PII has a cpu temp of 45 and a mainboard temp of 29 degrees The MB temp is always 7 to 8 degrees above room temp and the cpu 15 to 17 degrees above that.

Yeah. > I use a wild-eyed-guess of 5-8 degrees for this difference. I suppose this depends critically on where the temp sensor is. With Athlons the temp sensor isn't integrated into the chip package, you have to stuff it between the fins on the heat sink. In these circumstances you may be dropping a lot more than 8 degrees. > > In my own experience, I have seen CPUs run for years at above 50 degrees, > and have *not* seen any CPUs stop working at even a measured 62 degrees. My dual PII systems both use Supermicro boards which have integrated sensors. Typically the M/B sensor runs 4C below the CPU temp, I reckon to keep below 45C for safety. One of the systems had the PSU fan fail, the temps rose to 55C (MB) 59C (CPU) at which point errors started. (So I rewound to a previous "safe" save file when the fan was fixed.) Of course it could be that the errors were due to overheated M/B components, or memory, rather than the CPU. > The torture-test mode of 'prime' should soon detect any CPU that > misbehaves (for instance, because of heat).

The > extreme overclockers get it down to -40 or even -50 :-) In my opinion that is being excessively conservative. I do not know of any CPU that is *rated* at less than 60 degrees, and many Intel CPUs are rated at 70 degrees or higher. (To me, "rated" means the manufacturer claims it will keep working correctly.) In my opinion the main thing you have to worry about is how much hotter the inside of the chip is than what your probe (outside the chip) is measuring. I use a wild-eyed-guess of 5-8 degrees for this difference. In my own experience, I have seen CPUs run for years at above 50 degrees, and have *not* seen any CPUs stop working at even a measured 62 degrees. In fact, I consider your temperature reading of 42 degrees to be *low*. The torture-test mode of 'prime' should soon detect any CPU that misbehaves (for instance, because of heat). If you do not get any errors in 48 hours of running 'prime' (with room temperature as hot as you will ever have it) then my suggestion is to *not* worry about CPU temperature. mikus _ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers

I think I've heard numbers saying that 50 is critical, and at 60, your CPU simply won't work anymore. My own usually runs at 28 or 29, even though the fan isn't especially good. The extreme overclockers get it down to -40 or even -50 :-) As long as it's stable, though, it probably won't harm your CPU, but to be on the safe side, I would have installed some kind of extra cooling. /* Steinar */ _ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: Motherboard Temperature
That must be 42 degrees Celsius..could you explain where the temp is being read?

Mersenne: Motherboard Temperature
Hi, Soory to be a little off topic, can somebody tell me how hot a motherboard should be running? I have a Celeron 466 and an ASUS P2B-B. It claims to be 42 degrees after some days of continuous use. Is this normal? Thanks, Michael. _ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
