GeForce 8800 GT, with an 3rd party cooler and fan speed? - 2008/04/03 18:02 Hi, I have a Point of View GeForce 8800 GT 512MB, and I just bought a Thermalright HR03-GT with a 92mm cooling fan. My problem is that the connector on the board have 4 pins, and the fan's connector only have three. I know that the 4th pin has something about PWM, but no more. My question is how should I do to have the fan speed regulate by the graphics card? Thanks...

Re:GeForce 8800 GT, with an 3rd party cooler and fan speed? - 2008/04/04 16:38 Well what you should have is a fan with only a 3-pin connection that way you are certain that the three lines are doing the function as required, meaning two to give the power and one for the fan speed. With the 4-pin connection I am not sure how you should connect as the 3rd and 4th pin might be somehow switch versus the function of the 3-pin connection.

Re:GeForce 8800 GT, with an 3rd party cooler and fan speed? - 2008/04/11 19:57 Okay thanks, on my board I have a 4-pin connector from the stock rad witch had speed regulation control for the temperature. I have recovered a 3-pin connector that I can plug in the 92mm fan connector, and a 4-pin connector. I have wired pin 1 on pin 1, 2 on 2, and the pin from the speed of fan on the pin 3 of the 4-pin connector. Do you think it shoud work? I think other people have already change their GeForce 8800 GT cooler, how have they connect the fan on their board?

Well on that I have no clue, and you should check the schematics really of what each pin means on the 3-pin wire and the 4-pin wire. Though I have my doubts it will work somehow. Others I believe don't care about the fans speed when they go for a 3rd party cooler as they just care that it is more silent and cooling better.
