Opening error and fans running on top. #18

I'm having some trouble with controlling my MacBook Pro 3.1's fans with macfanctld in Ubuntu 14.04.

From startup they run with top speed (6000rpm) although the sensor temperatures are around 50°C. When running macfanctld with the -f option I get the following:

Running in foreground, log to stdout.
Using parameters:
temp_avg_floor: 55

I tried chmod-ing those files and restarting macfanctld, which had no effect. After a reeboot the error even continues because the acces right are reset.

This fan noise is driving me crazy by now, is there any possibility to fix this?
Thanks!

Try to set log level to max and see which sensor is driving the fan

Hi Mike, thanks for the reply.

Now it gives me the following:

But the fans do clearly not run at base speed of 2000rpm. So what's going wrong here?

Does /sys/devices/platform/applesmc.768/fan1_min (and the others) exist in the file system?

if so, try:

$ sudo su
% echo “2000” > /sys/devices/platform/applesmc.768/fan1_min

If you installed macfanctld correct, it will be run as a daemon as root. If not, perhaps privileges is the issue.

Hope that helps.

All files exist in the system. Reading them gives me "2000" for the _min-files and and "0" for the _manual-files. I also checked with top that the process "macfanctld" is running as root, it is.
The acces permissions of the files are all read and write for user, read only for group and others. Changing them is pointless as they are being reset when rebooting.

Strange. In that case the SMC (i.e. them mac bios) might be driving the fans somehow.

Try to reset the SMC. Apart from that, I have no other ideas.

You should not have to do anything of the like.

Reseted the SMC with no effect.
I would guess that the problem is one broken temp sensor (the one which I excluded), because acoording to the sensor command it senses a temperature of -150 somewhat degrees.
