Hello everyone,
I am a MSI Gtx 550Ti user and having problems with my new gpu fan. I can't control the fan speed. Here what happened and what i did for solve the problem: I had problems/accidents with my 550Ti's cooler, and bought a new gpu cooler. New cooler has 3 pin connector. My gpu has 4 pin connector, so i decided to connect the cooler cable with psu. New cooler came with 3 pin to 4 pin molex adapter. As you can guess i connected the cable with psu via 3 pin to 4 pin molex. Actually fan is working. But i can't control the fan speed, it is always on the lowest setting(default settings). Tried different control programs like msi afterburner and none of them worked.
I also tried to uninstall and install all drivers and programs related wtih gpu and fan control. But problem is same. I actually have 1 empty 3 pin fan connector on my motherboard. Cooler's cable wasn't long enough to connect with 3 pin connector. Should i extend the 3 pin cable to connect with motherboard? Does that work?
There is one thing that i noticed with adapter which came with cooler. Adapter's 3 pin converter actually has 2 cable. I mean cooler's cable has 3 female connector, each connector has its own cable(totaly 3 cable). Adapter also has 3 pin male converter. But only 2 of them has cable connection, so 1 pin is empty. Here is the a quite similar picture of my adapter:
Why i am telling this because, as i know PWM needs 4 pin connector to work properly, so i need 4 pin connector. Do i really need 4 pin connector? Is there any way to control the fan speed without using fan controller?
