Pentium 4 3 HSF fan speed
Hi,
I have a boxed Intel P4 Pentuim 4 3.0 Ghz with HSF. Should the CPU fan speed up as the CPU temperature gets hotter? Mine stays at a constant 2500 rpm no matter what the CPU temperature reaches. (I stop it when the active monitor objects at 70 deg. C.) Cheers, Simon. |

The fan supplied with current versions of the boxed, Intel P4 CPU should have its own fan speed control. And it should increase speed as the CPU processor increases *unless* there is a CPU fan temperature control also in active competition, via the 3-pin CPU header on the motherboard. But even at 2,500 RPM, the CPU temperature should not be excessive unless the HS was installed incorrectly or there is poor air flow through the computer case. |

The CPU fan is plugged into the CPU fan header on an Intel D865PERL motherboard. What would be in active competition? Would the Intel Precision Cooling stuff do it? In normal use, the temperature is not excessive. The only time there is a problem is when I run video rendering (TMPMeg) software that pegs the CPU at 100% for several hours. Then it slowly creeps up until it hits 70 deg C. (The short-term solution is to take the case off.) The case fans are at full-speed at 62 deg C (reduced from the standard 65 deg C). I have improved the fans in the case, and that reduced the normal operating temperature 2 or 3 degress. Cheers, Simon. |
