As my processor is already running at an perfectly acceptable temperature, I don't see the need for it. :) By using a good heatsink and quality fan, I've never had a heatsink get even remotely warm.

Copper based CPU cooler! prescott 2.8 GHz, Asus MB p4p800se. The client is working now over several month without any hardware or OS problems. Asus probe and other tools showing the same temperature range. It looks like, there is a problem with the cpu-sensor. The mainbord-sensor shows 30 degrees C. |

> By using a good heatsink and quality fan, I've never had a heatsink get even remotely warm. But you want the heatsink to be warm- that means it's removing the heat from the CPU. Although if you've got really low ambient temperatures (less than 20°c or so) i guess things would always be pretty cool. Grant Darwin NT |

My P4 1.8GHz: CPU: 37C Sys: 32C With only 1 additional fan. No matter which project I run. |

I dusted it out a few days ago now i get 35C as highest temp :D http://img226.exs.cx/img226/9184/cpu4pq.jpg |

With HT enabled and BOINC running I get 45° for the cpu and 28°C for the system with a 3.2 Prescott. With HT off the temps drop a bit. |

with LGA775 P4 530 (3.0 Ghz) running at 3.0 gets temps under load with SETI about 66°, Einstein and CPDN take it as high as 72°. running at 3.29 gets the same temps. i think that the Asus p5p800 sensors are not reading correctly. i did a lot of searching and found that the 775s are just very hot, and no heatsink seems to work overall, though some ppl have cooler running chips. the agreed upon best heatsink zalman CNPS7700-Cu some ppl still had temps over 79º. The only way that worked for everyone was watercooling.. i may be looking at that route myself. S@h Berkeley's Staff Friends Club |

If the heat never gets from the CPU to the heatsink, then the heatsink would run cool.... |

Trust me, I DO monitor the CPU temps from time to time, just to make sure everything's ok. :) You will be assimilated...bunghole! |

The temperatures are reported more accurately. I've had a couple of motherboards where i had to flash the BIOS to sort out an issue i was having, and after doing so the CPU temperatures were (in one case) almost 15 degrees lower. In the other they went up by about a degree. Interestingly there was no mention on the BIOS page that the temperature reporting was one of the changes made in that version. Grant Darwin NT |
