How do I change the speed of my case fan?

post #1 of 7
Thread Starter 
I bought a case fan and it arrived yesterday, the Arctic F8.
It had a 3-pin female port thing and I found a connector on the motherboard so installed it there, it was located below my video card slot and above the SATA ports.
I am having trouble finding out how to slow it down a little because when installed on the side of my case it makes a loud sucking sound.
I've tried speedfan but I don't really get it, when I change any speeds nothing happens.
any ideas?
Thanks.

You should be able to adjust the speed in your motherboard's BIOS, but you'll have to know which connector you used. Your motherboard's manual should provide you with all the information you need.

As he said, try the BIOS. Some MB's will control the speed for 3 pin fans. Others will not. Controlling the speed of a 3 pin fan requires changing the voltage. 4 pin fans have their speed controlled using pulse width modulation (turning the fan on and off rapidly).

You could also:
  • Option 1 - Disconnect it from the MB and connect it to the PSU, stepping the voltage down either with a resistor or by adjusting the wiring. Kits are available.
  • Option 2 - Disconnect it from the MB and connect it to a third-party fan controller (very flexible option...and you probably have a spare 5.25" bay for such a device)
  • Option 3 - Replace it with a 4 pin PWM fan (allows you to setup some fairly advanced speed control curves using software, but perhaps not as fine tunable as a fan controller).

cheers,

I just tried changing the fan speed in RPM on the BIOS but It is all greyed out for all the fans. It's running at 2150rpm by the way.

How would I go about changing the voltage? I couldn't change anything on that specific page on BIOS and I am a little worried I will change a voltage I'm not supposed to which will end up killing my PC :S

Your MB probably doesn't support changing speed for 3 pin fans then. Thus, if you want to keep that fan (rather than replace it with a PWM), you can pursue one of the first two options that I listed above. For option 1:

If you are handy, you can try this:

...or just buy something like this:

...or one of the many similar options.

Ahh, just noticed that you are in the UK, so here is product on a site that uses that funny £ symbol: wink.gif

I reeeeallly don't want to spend any money, and I don't think I want to take apart my fan especially when it doesn't have a molex adapter soI will just leave it standing in the middle of my PC where it doesn't make much noise biggrin.gif
lol it was only £2.50 on amazon ($3.50 for you with the funny sign tongue.gif)
thanks for all your help though smile.gif
