Default BIOS for FANs PWM:

• CPU Fan: Enabled
  • Fan Off(0x68) 30
  • Fan Start(0x69) 35
  • TFull Speed(0x6A) 92
  • Start PWM(0x6B) 40
  • Automatic Mode Control (0x6C) 2
  • Delta Temperature(0x6D) 1
• System Fan & System Fan 2
  • Fan Off(0x70) 20
  • Fan Start(0x71) 25
  • TFull Speed(0x72) 80
  • Start PWM(0x73) 130
  • Automatic Mode Control (0x74) 4
  • Delta Temperature(0x75) 1

Description:

• Fan OFF: At this temperature the fan remains off.
• Fan Start: At this temperature the fan starts to rotate.
• Full Speed: At this temperature the fan will spin at full speed.
• Start PWM: This is the percentage of speed at which you want your fan to start spinning when it reaches the temperature indicated in “Fan Start”.
• Automatic Mode Control: It is very important to set this field to 29, otherwise my fans would never ROTATE. I didn't manage to find out much information about this parameter.
• Delta temperature: I haven't found much more information.

I asked Aoostar directly about that and got the following response:

“The automatic mode control value increases, and the entire PWM value goes positive, which can be interpreted as the slope. The delta temperature can be interpreted as the error value. If you want the fan to rotate faster, you can adjust the start pwm or the automatic mode control slope value. Depending on your situation, you have to test them one by one.”

File found on Internet: wtr_r7_5825u_bios.rar, contains folder AR5000-MI2_231215A. Not tried.

Running on Hynix DDR4 32 GB 3200MHz CL22 (HMAA4GS7AJR8N-XN). But no EDAC driver loaded in Kernel.

No driver for ITE IT8613e?
