when i run pwmconfig I get this:
/usr/local/sbin/pwmconfig: There are no pwm-capable sensor modules installed
even though sensors returns:
atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage: +0.99 V (min = +0.80 V, max = +1.80 V)
+3.3 Voltage: +3.31 V (min = +2.97 V, max = +3.63 V)
+5 Voltage: +5.02 V (min = +4.50 V, max = +5.50 V)
+12 Voltage: +11.97 V (min = +10.20 V, max = +13.80 V)
CPU FAN Speed: 2385 RPM (min = 600 RPM)
CHASSIS FAN Speed:1240 RPM (min = 600 RPM)
POWER FAN Speed: 4245 RPM (min = 600 RPM)
CPU Temperature: +42.0°C (high = +60.0°C, crit = +95.0°C)
MB Temperature: +39.0°C (high = +45.0°C, crit = +95.0°C)
I tried to read the page at
http://www.lm-sensors.org/wiki/AsusFormulaHacking but at the moment
it's not making much sense to me. I could just need some sleep.
I wonder if my ASUS M3N78-EM motherboard just isn't compatible with fancontrol
Does anyone know?
