Hi guys,

I have been facing this problem which is quite similar.
I am using E6600|Intel DG965OT | cooler master heatsink CPU Cooler (DI5-9JD3A-P9) 4 pin - dinasaur heatsink

I got this heatsink from Startec. At that time, I am really new to cooling.

Problem : when cpu activity high/benchmarking, the fan noise is like vacuum cleaner bcos turning at almost 4000 rpm. (the intel bios that control the fan speed is really not user friendly, u cant set the fan speed lower or whatever speed u wan. all those using intel motherboard will know this problem. software like speedfan cant work with intel motherboard)

This is the link of my cpu cooler loh (really outdated. using presscot for conroe, isnt i noob ): -

I try to use fan controller to adjust max speed. Can I just buy any fan controller. will it work. what need to check on fan controller.
I am using it for HTPC. silence is everything
