Cant change fan speed after installing new motherboard

I have an Packardbell imeadia l4875, the motherboard that came with it when i bought it broke and i could control the case fan speed before it broke, so i bought a new motherboard the ASRock H61M-VG4 and now i cant change the fan speed of the case fan but i can controll the CPU fan. And they are plugged as they should be on the MOBO.

Ive tried changing the settings in the MOBO but nothing happens. Any help pls?

  1. Is the header the fan is plugged into 3pin or 4pin? And is the fan's connector 3pin or 4pin?
  2. The fan connected is 3pin connected to 4pin on the motherboard.
  3. Best answer
    3 pin fans can only he controlled by voltage

    4 pin fans can be controlled by voltage or pwm.

    That h61 board only supports pwm control, so you need a 4 pin fan if you want to regulate the speed in any way.
  4. Hmmm i see how it works. What 4 pin fan do you recommend?
