Also if you couldn t locate any fan settings in your bios to begin with this means that your motherboard probably doesn t support this option.
3 pin case fan speed.
Use pwm for a 4 pin connector.
So i m basically done.
Lastly this method will only allow you to control the speed of cpu and system fans.
This fan hub takes the pwm signal and converts it into corresponding dc voltage for 3 pin fans so that their speeds can be controlled.
In which case you should move on to the next.
3 pin fans still have an rpm sensor on them and most mainboards can still vary their speed based on temperature.
3 pin fans use simple voltage control for adjust the fan speed.
The signal wire measures how fast the fan is moving without any controls for the fan s speed.
This functionality is very unique and you won t get this in other fan hubs.
It is the only fan hub to do such a speed control thing for 3 pin case fans.
Use voltage for a 3 pin connector.
With this type fan speed is typically controlled by increasing or decreasing the voltage over the power wire.
A three pin connector is basically power 5 12 volt ground and signal.
In my case my cpu fan is the only 4 pin fan in my computer and my motherboard doesn t support voltage control for my 3 pin fans.
