I’ve got a pot controller and I’m actually thinking of bagging FanControl since I can’t get it to detect the fans I actually want to use it with and throwing that on my secondary air in. i mean you can also buy a gpu to fan adapter i guess and use the phoby 3pin to pwm thing to make the fans pwm as most gpus i think use pwm fans now. My bios controller won’t use gpu temp as a sensor though, and the cpu temp is useless for fan control because all it does is say it’s cool.Īrgb controllers that alow for gpu control. Half of me wants to install one for just-in-case, but I don’t seem to be able to get the thing hot enough to where it could possibly matter. I didn’t intend to buy a passive cpu cooler but I’ll take it. Thing came with 2 and I’m using zero of them. The thing doesn’t hit 50c more or less ever. I actually removed the last cpu fan as it’s basically not necessary at all with that giant cooler. It’s the thing that makes all the heat and noise. The thing I need is to control the side case fans (there are 4 possible side fans in this case) using gpu temperature. I bought some fans thinking they were 4 pin but they are only 3 pin. Apparently I’ve got to have 4pin pwm fans to use the FanControl app. I actually bought a fan extension cable with a resistor in it long ago which will bring a fan from 100% to 80%. You could reduce the speed of a fan by adding a single resistor in series with the voltage wire, if you want I can give you the formulas to use to determine what resistor value to use. Usually they mass produce those circuit boards so they use cheapest ICs possible for those without PWM signal input. I suppose it's not impossible, but it's really unlikely that the circuit board in the fan hub has 3 contacts for wires but the manufacturer only used 3 wires and a 3 pin connector to save a penny. Some motherboards have controllers which will detect a fan doesn't change rpm when sending pwm signal, and switch to adjusting the output voltage going to the fan to control fan speed (ex change voltage between 5v and 12v) 3 pin fans are : voltage, ground, rpm sensorĤ pin fans are : voltage, ground, rpm sensor, pwm signal
