Graphics card cooling fan died

[dabbler]

Yesterday my graphics card (Nvidia 9600GT) cooling fan died on me, so I removed it and fitted an old AMD CPU cooling fan onto the card and connected the lead to the mobo 'case fan' socket (3-pin). this works really well but the only problem is that it runs at full speed (5000 rpm according to my 'speedfan' app.), ie. about double the CPU fan speed, and makes a hell of a lot of noise. I most certainly will notice when this one fails on me .

Any way of reducing the speed of the thing with some sort of control? I'm sure there must be fan speed controllers out there somewhere, or do I fit a variable voltage supply like a LM317 to the 12V rail, a resistor and a pot? And what is a recommended speed to run it?

Any suggestions?

You could try reducing the speed with SpeedFan, a free program.

Otherwise a cheap and pretty decent Zalman GPU cooler would be around R200 - i.e. Zalman VF902-CU.

I use a Zalman fan controller like this:http://www.prophecy.co.za/zalman-mate2-speed-mini-controller-511v-output-p-19638.html

This thing seems exactly what I need. Thx
