Hi Ross, Please leave the list in Cc so others can read and help. I'm adding it back.

Well if the drivers are happy together maybe I am needlessly anxious. For reference, the driver names are "thermal", "it87" and "asus-wmi". However thermal is frequently built into the kernel so you can't remove it. > > Can we see the output of "sensors" on your machine? > > Sure: > acpitz-virtual-0 > Adapter: Virtual device > temp1: +27.8°C (crit = +96.0°C) > temp2: +29.8°C (crit = +96.0°C) > > coretemp-isa-0000 > Adapter: ISA adapter > Physical id 0: +42.0°C (high = +76.0°C, crit = +95.0°C) > Core 0: +42.0°C (high = +76.0°C, crit = +95.0°C) > Core 1: +41.0°C (high = +76.0°C, crit = +95.0°C) > > it8771-isa-0290 > Adapter: ISA adapter > in0: +1.01 V (min = +0.00 V, max = +3.06 V) > in1: +1.49 V (min = +0.00 V, max = +3.06 V) > in2: +2.05 V (min = +0.00 V, max = +3.06 V) > in3: +2.00 V (min = +0.00 V, max = +3.06 V) > in4: +2.04 V (min = +0.00 V, max = +3.06 V) > in5: +2.23 V (min = +0.00 V, max = +3.06 V) > in6: +2.26 V (min = +0.00 V, max = +3.06 V) > 3VSB: +1.42 V (min = +0.00 V, max = +6.12 V) > Vbat: +3.34 V > fan1: 2766 RPM (min = 41 RPM) > fan2: 1341 RPM (min = 84 RPM) > temp1: +40.0°C (low = -1.0°C, high = +127.0°C) sensor = thermistor > temp2: +40.0°C (low = -1.0°C, high = +127.0°C) sensor = thermistor > temp3: -8.0°C (low = -1.0°C, high = +127.0°C) sensor = thermistor > intrusion0: OK It is strange that "asus" doesn't show up here, while pwmconfig sees it.

On Asus boards I have here, I can select a profile and have generally been happy with the "Silent" profile, but I suppose it depends on the board, fans, ears, etc. > > Are you using 3-pin fans, 4-pin fans or a mix of both? > > I'm using a stock Intel Core i3 cooler (that's the one spinning at up > 2766rpm - I've run it on another motherboard before and had full control of > it). I think that's 3-pin. The secondary case fan, I'm not so sure about, > it's what came with the case and I'd have to open it to check. Every Intel stock cooler I've seen since 2007 had a 4-pin fan, so I'm surprised that you say yours has only 3 pins. I'd think every recent motherboard expects 4-pin fans at least for the CPU, and CPU fan speed control wouldn't work (at all) if you use a 3-pin fan. As a matter of fact, I downloaded the manual for your board and it says that both the CPU fan header and the chassis fan header have 4 pins. There doesn't seem to be a jumper to switch to 3-pin mode, so unless there is a BIOS option for it, or some transparent magic to auto-detect what's connected, I'd say you must use 4-pin fans for both the CPU and the chassis. > > (...) > > I would like you to check if PWM values stick.

This is very odd, as 0 normally means fans stopped. Also the first results from pwmconfig were strange but completely different from what you are reporting now. What's the value of pwm1_enable and pwm2_enable? -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
