The fans are not true 4-pin fans. Each has a forked end with a standard 3 pin fan speed connector and a 2 pin Molex connector. These are NOT built-in PWM fans. You may have a motherboard that handles the speed well, but they only work on a 3-wire system. They are well made and appear to be of good quality. You are very quiet! However, they don't let much air through. These are 1200 RPM fans that are 100% on. I'm guessing around 25 CFM. If that's enough, that's great. I will use them on a case but not on a radiator because they just can't move enough air.
