My case fan is always at 100%, is there a way to change or atleast control it because a fan at 100% when surfing is disturbing.

Many case fans are 3pin. Most motherboards are 4pin. This isn't a problem. 3pin work on 4pin no issue. But there's a catch. 4pin is pwm, it's a constant 12v. 3pin fans work on variable voltage usually 7v-12v to control speeds.

So in your bios, you need to change control of that header to auto/voltage instead of pwm

No. You already have a 3pin. Your motherboard is setup to control 4pin. Go into bios and change the fan control from pwm to auto/voltage for that header.

You just need to setup the motherboard/bios for the equipment you want to use. If you buy a pure wings2 pwm, then you'd not need to change the mobo, but if that pure wings2 is a 3pin, then you would still need to make the change.
