asrock z77 extreme4 cpu fan speed

post #1 of 9
Thread Starter 
Hi. I am having trouble configuring automatic CPU fan speed with this mobo. By default it runs at max and is quite loud with my 212evo. If I set the target speed low, it gets nice and quiet, however the fans never ramp up under load, even though the target temp is set at 50. Just ran IBT and got to 80 without the fans increasing. Am I doing something wrong here? Any help is greatly appreciated.

Isnt there a 'Auto' option anywhere?

On my mobo, I can set what type of modulation I want it to use, is there an option saying 'Voltage Modulation' or 'PWM Modulation' or similar?

Can you post a screenshot?

Not able to post a screen atm, but the only options are

CPU fan:
  1. Full on
  2. Automatic

If Automatic:

  1. Target fan speed
  2. Target Temperature




I'm assuming it is supposed to ramp up when it hits the target temperature, but it just sits at whatever fan speed i set as target speed.

The feature is working exactly like it's supposed to. Unless you want to do some insanely complicated programming of your own windows program, it's going to do that.

I thought it was supposed to gain fan speed if the temperature crosses the barrier? It stayed at low speed all the way up to 80. Maybe I am just misunderstanding what it is supposed to do. I am just trying to make it quiet at idle, and ramp up when the heat increases. Right now just whatever speed I set it at is a permanent speed no matter the temp.

No, it seems like it should work that way but it tries to keep it below that temperature actually. So even 35c it starts raising the speed if you have it set to 50.

I'm having this issue as well but i don't quite understand what you mean. So, is there no actual way to have it automatically ramp the fan speed up when it passes a certain threshold? MY old motherboard just that flawlessly without me having to touch a single setting. I assume this would be similar.
