P4 2.53B, Intel retail HSF, 46C (115F) this in an Antec plus1080 case, with 2 case fans running at a very slow speed, the 2 motherboard temp sensors are reading 38C (100F). If I hook the case fans up to straight 12V rather than the speed reduced fan power coming out of the Antec power supply, the case temp drops 5C or more in a matter of seconds, and the CPU temp tracks. hey, speaking of... anyone care to point me to something I can understand on how to configure lm_sensors in Linux to work with an Intel server board? I'm getting no readings... # sensors Can't access /proc file /proc/sys/dev/sensors/chips or /proc/bus/i2c unreadable; Make sure you have done 'modprobe i2c-proc'! # modprobe i2c-proc # sensors No sensors found! (this is with Redhat 8 on a E7501 based dual xeon server board, the SE7501WV2, kernel linux-2.4.18-27.8.0) _ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers

It's Odd. I wonder if a fan stalled.

However the P4's I'm running are all reasonably cool: P4 1.8A, retail box HSF, 50C P4 2.53B, Zalman CuAl HSF, <2000 rpm, 44C P4 2.66B, Zalman CuAl HSF, <2000 rpm, 45C Zalman HSF comes with a rheostat which allows you to vary the fan speed from (approx) 1500 - 3000 rpm - below 2000 rpm it's highly unlikely that you will be able to hear the fan, so this HSF is quiet as well as effective. The only change I made to Zalman's installation instructions was to use Arctic Silver thermal compund instead of the small tube of gloop included in the Zalman kit. Note, I'm not saying Zalman's gloop is useless, but Arctic Silver is usually a couple of degrees cooler than other stuff. A decently ventilated case helps, too ...
