CPU cooler fan speed

Without sounding too dumb, How do I change the fan speed of my CPU cooler?

andy_mk3 · 24 Apr 2011 at 21:51

There's usually settings for it in your BIOS.

Dokinator · 24 Apr 2011 at 21:52

I did have a look but I couldn't see :S

As long as you have a PWM fan, you can adjust the speed in the BIOS by either reducing the speed and using a minimum temperature where it speeds up under load, or using a maximum speed the fan will be allowed to spin at, it will depend on what specific options are available for your motherboard.

Software wise you can use 'speedfan' which will allow you to adjust in percentages but again requires a PWM fan.

You can control non-PWM fans too.

Im guessing my Titan Fenrir Evo is PWM?

andy_mk3 · 24 Apr 2011 at 21:56

Yes it is. What mobo do you have?

Gigabyte GA-770TA-UD3

It's under PC Health Status in BIOS, you have CPU Smart Fan options at the bottom there.

Awesome Thank you

I can just set it to PWM and have no values to change, should I be able to change values, if not, what does setting it to PWM actually do?

Pretty sure pwm means it changes with the heat of your cpu?

Yep, PWM means it will raise and lower the RPM of the CPU fan depending on load. It's the best choice.

So what's the difference between that and auto

SubScape · 25 Apr 2011 at 16:10

I'm not sure as I don't have your mobo, but you shouldn't need to change it to auto

Dokinator · 25 Apr 2011 at 18:17

Auto is what it was originally on

Leave it on auto, you're trying to fix something that isn't broken.

The most you can do on Gigabyte boards is use easytune to increase fan speeds based on temps but the board is doing that already.

I was just going to put the cooler on max, but I suppose its not really needed if I am currently running at 35 under small load

Menthis · 26 Apr 2011 at 15:55

Yeah i put mine on max and was had a go at, as there is no need to have it on max where it is not even being used, when idle. just gets loud and very annoying as well

Set to "Auto" when using 3-pin fan.
