How can TMS-205 be a PWM controller with only 3 pin headers. Don't you need 4th pin for PWM? How about the control on RP-1200 or
RP-1005? Are they also PWM based fan controllers? This is confusing?

Koolance three pin fans receive a varied power input (modulation) where as other four pin PWM fans receive a constant power input and have a fourth control wire for the PWM signal. All our controllers (TMS-200/205, RP-1005/1200, CTR-SPD/CD) have been designed to control three pin PWM fans. Four pin PWM fans could work with our controllers but you'd need an special adapter to a three pin plug. Just wiring the power, ground and tach would only run the fan at full speed.

Non-PWM fans can still be powered by our controllers but they usually only operate well at full power. Under 100% power non-PWM fans don't always run or may not adjust speed well.

We don't actively maintain a compatibility list of fans due to the large variety available. I've noted the compatibility for the Noiseblockers and Yate Loons (perhaps we'll start a list in the future).

Strange that you were having issues with our FAN-14025HLED, sverreb. We've tested those fans with our controllers before. Did you buy them recently? There may be a problem with the fans you purchased or the TMS board. We'll try testing some current stock.
