I have a BioStar A770E3 board with a 4pin CPU connector, I also installed a Corsair H60 Watercooler and the fan is NOISY (idk why) for it. I want to use my Cooler Master fan with my cooler but its only a 3pin connector. The manual says that the 4th pin is for SmartFan Control, is this needed? Can I plug my 3pin in to the 4pin? is there any possibility to rig my Cooler Master to the water cooler?

Thank you!

You're perfectly fine to use the 3 pin connector on the 4 pin header, just be sure to use the rightmost 3 prongs (there should be a groove on the back of the fan connector that fits in with the mobo). SmartFan Control is just used for more precise fan speed control (usually for the CPU fan).

Yes you just need to make sure which pins are the correct ones to plug it into.. meaning which side left or right.. The 4th pin is just a fan speed sensor
