Noisy Heatsink Fan

[Computician]

Hi All,

I have an HP Pavilion 1030n machine at home. The processor is Intel P4 HT (Prescott). The problem is the the heat-sink fan goes to full blast periodically (whenever I launch a program). Although this processor is notorious for its high temperature operation and I have checked the temperature of the processor while in operation which stays between (55~80C). 55~60C at normal operation but it spikes to 80C for a few moments when a program starts or when I am running a AV scan. The motherboard monitor (presumably) sends a signal to the heat sink fan at it goes mad. Under normal operation the fan it quiet.
i am wondering if there is a solution to this instantaneous high speed of the fan?
I have physically checked the heat sink and fan assembly, its clean/dust free, the fan is ok, heat sink is firmly pasted to the processor by the thermal paste. I have tried speedfan, it doesn't seem to work in auto mode on my machine!
Any suggestion.

Regards

I would just replace the noisy fan, with one of these:

Zalman CNPS7700-Cu or one similar, as they are only around $40...

If this is not a laptop, make sure you have good airflow. If the case is completely sealed, then id reccomend making a hole in the side for a fan to blow air in and have a fan on the back of the case blowing out. Definitely follow badbigben's suggestion on getting a zalman fan. They rock and are quiet unless you push them to the max lol.
