Hey guys, does anyone have experience with the SpeedFan program? Do you know if it supports 3-pin fan control? Thanks for the help!

No none of them do. the 4th pin on the header is the pin that controls speed or RPM. Without it there is no way to control the speed without an inline adapater.

Wut. You can control fan speed without a 4-pin plug. Not as accurately as a 4-pin, but definitely controllable.

Got it. The reason I'm asking is because I'm thinking of getting a pair of Gentle Typhoons for a radiator and they have only 3 pins. I don't know if there's any downside to that though...

Incorrect. 4th pin is for PWM control which is more accurate than DC control of 3pins. There are ton of ways to control 3pins. Starting from manual knobs and ending to Speedfan using GPU temps as control source.

Controlling 3pins isn't as accurate and you will have higher rpm starting point. Something like 40% as lowest running speed. You can go for 0%/rpm but nothing in between. My Spectre Pros could go down to 30% after been spinning for awhile but required 40% to start from 0.

I control 3-pin case fans using SpeedFan works like a charm. I'm assuming the fans are plugged to a motherboard header ...BIOS setting should be DC mode not PWM mode.
