Hi guys...

You want like me to reduce fan noise from your PC when you are browsing on the web for example, and especialy the video card fan because you didn't find any soft working with your hardware (i have a wintech GeForce8800 GT).
With just a couple of some basic electronic components you could do it in a hardware way.

Electrical part + components list + PCB : http://rapidshare.com/files/101597371/ventil.pdf.html

You just need to place the KTY10 component in contact with the radiator of your video card (or other).
J1 is the 12v power from the PC
J2 is the fan power

R2 is to set the min speed fan
R7 is to set the trigger

Now you can surf in silent mode, and if you launch for example CRYSIS, your fan increases automaticaly its speed and as soon as you stop gaming and return to winword or firefox or other working office the silent reappears because the fan speed decrease automaticaly !
