Processor Overheat ?
dkny Sep-14-01 04:10 PM
I am using P4 1.5 wit intel D850GB motherboard. I wanna know what is the normal temperature for the processor when the processor fan is operate. My CPU fan spining at around 2300 to 2600 RPM.. will it too slow ? I sometime found the CPU temperature up to 55c wit Intel Active Monitor.Is that normal ?

My previous response was based on searching for P4 heat-sink fans and seeing fan speeds for non-Intel fans in the neighborhood of 4,500 to 7,000 RPM. I have subsequently learned that the boxed processors have a variable-speed fan that uses the chassis temperature to regulate speed, but I cannot find RPM numbers. I believe I read some comments not too long ago about stock P4 fans being slow, but do not recall for sure. 55C appears high, but the max CPU temp in the specs is much higher, as is the case with all CPU specs. Some temperature tests for non-Intel fans are at http://www.a1-electronics.co.uk/Heatsinks_Cases/Heatsinks/Review_P4June01.html. One certainly does not run a processor at the specified maximum or anywhere near the high. The most informative info on the subject is a write-up by Intel on boxed P4ís at http://support.intel.com/support/processors/pentium4/intnotes.htm#In_the_Boxed_Processor. Perhaps other readers have some numbers for boxed P4s. Larry
