But if you set this pwm2 to 0, the CPU fan runs with full speed (same rpm as with pwm2=255) The other pwm output with a fan connected (pwm4) does not behave like this and stops the fan with pwm0. > Anyway, I would recommend to use the chip's automatic fan control > if possible.

But it was not possible to go that low with the fan speed within the BIOS settings (20% or 25% is the minimum IIRC) But with my current setup (i3-4130T, 35W TDP) the CPU temperature is the last problem. I can go down till pwm 7, the fan (A.C. Freezer 13) still runs silent and stable at ~550rpm. @Michael: Could you give me some feedback to my mainboard config file? Could you especially take a look at the +5V and +12V readings, compared to the reading in the BIOS. Its possible that they are inverted. But with my readings from the PSU I had idea how to verify the assignment because the raw values were almost the same.. The scaling should be ok. Thanks alot! - -- kind regards mathias -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlLf+VMACgkQnfTEjDUZ2fP6ewCg3KDhSK3E0GrIm/CmeafSXvNh sCUAoKnYhy61cXYfA+F8ElQ7qABqmkbe =3TdR -----END PGP SIGNATURE----- _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
