Re: CPU fan with full speed

No ... those are separate drivers, and different sensors. Also, the coretemp
reading is not really that exact. Especially at low temperatures it can be quite
a bit off, as far as I remember by 10 degrees C or more. It is more accurate at
very high temperatures.
I see, interesting - for some reason I always thought the Intel censors are more accurate (judging by their measurements, because when I place a load on that machine, both Intel CPU readings jump, but the f71882fg driver barely moves a degree or two and stays in line with the rest of the sensors, which doesn't really makes sense - when the CPU is under load its temperature should rise rapidly).

Also, keep in mind that you have a different chip. pwm3_auto_channels_pwm
means something completely different on the f71882fg. For that chip, it is
not a bit map, but the temperature sensor index. 1..4 in pwmX_auto_channels_pwm
reflects temp[1..4]_input.
I am totally confused now! :-\

The driver has only 3 temperature readings: temp[1..3]_input, corresponding to CPU (single censor, even though I've got 2 cores) and 2 motherboard readings (one on the PC board extension card and another one on the main board itself).

So, I have the following values by default:

pwm1_auto_channels_pwm = 1 (1 binary - fan1)
pwm2_auto_channels_pwm = 2 (10 binary - fan2)
pwm3_auto_channels_pwm = 4 (100 binary - fan3)

Makes perfect sense since I do not have a 4th temperature reading anywhere on the system, unless you take into account the coretemp driver, which is in a different subdirectory: hwmon0 and not hwmon1 as the f71882fg driver is.
