I would like to understand the bios fan settings for this motherboard.
The asrock q1900 has got a 3pin cpu header.
From what I understand you can only control the fan speed with software if you have a 4 pin fan header.
So I can only use the bios to set the fan speed.
In the bios you have two options:
-Any speed between 0% and 100%
-Setting a target temperature and a fan speed
I'm mostly interested in the second setting.
I've been told before that if I set my target temperature to X and my fan speed to Y%, that the fan will operate at Y% speed until temp X is reached and then go up to 100% speed.
I've tested that but at 15C over my target temp my fan was still spinning at the base Y% speed.
I would appreciate it very much is some one could enlighten me on the topic.
