If not, is there an alternative for macbook pro's ? Thanks

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:

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!

Hi again Mikael! I have a separate issue with macfanctld I'd like to bring to your attention. On my hardware (a MacbookPro10,1 - quad-core i7 released in 2012), I find that the temperature reported by TC0P is consistently much lower than the actual CPU core temperatures. Here's an example of running the sensors command when my CPU is getting toasty:

$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +69.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +69.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +68.0°C  (high = +87.0°C, crit = +105.0°C)
Core 2:         +62.0°C  (high = +87.0°C, crit = +105.0°C)
Core 3:         +62.0°C  (high = +87.0°C, crit = +105.0°C)

applesmc-isa-0300
Adapter: ISA adapter
Left side  : 6201 RPM  (min = 6200 RPM)
Right side : 6200 RPM  (min = 6200 RPM)
TB0T:         +30.2°C  
TB1T:         +30.2°C  
TB2T:         +29.0°C  
TC0E:         +69.8°C  
TC0F:         +71.5°C  
TC0P:         +47.8°C  
TC1C:         +68.0°C  
TC2C:         +68.0°C  
TC3C:         +59.0°C  
TC4C:         +66.0°C  
TCFC:          +0.0°C  
TCGC:         +69.0°C  
TCSA:         +63.0°C  
TCTD:          +0.0°C  
TCXC:         +69.8°C  
TG0D:         +57.2°C  
TG0P:         +52.5°C  
TG1D:         +62.0°C  
TG1F:         +61.2°C  
TG1d:         +56.0°C  
TH0A:         +64.0°C  
TH0B:         +64.0°C  
TH0V:         +41.5°C  
TH0a:         +64.0°C  

Please note that the core temperatures reported via the first method are over 20°C higher than TC0P. I'm not sure, but I'm also guessing that the TC1C, TC2C, TC3C, and TC4C are probably the sensors for my different cores. Perhaps Apple moved the TC0P sensor to be physically farther from the CPU on newer hardware iterations? I don't know how to verify this or what all of the sensors above represent, but it does look that TC0P isn't an accurate assessment of CPU temperature on my hardware.

I wanted to see if you have any advice regarding possible fixes / patches? I'd be happy to help out / test any changes on my hardware.

Thanks!

Cheers,
Steve

Hello! Sorry for my english :)
I install macfanctld and start it by "macfanctld -f". It shows current fan speed as 0, but really current fan speed (in /sys/class/hwmon/hwmon1/device/fan1_output) near 3500 RPM.
I look source code and see, what fan1_manual hardcoded as "0", but it say driver to set speed automatically. As I understand, you limit min fan speed to force cooler rotate more quickly, but top speed not limited, and in case of this cooler always rotate more quick. I change fan1_manual to "1" and fan1_min to fan1_output, and when macfanctld start work as should.
IMHO my algoritm more functional, but it must set fan1_manual to 0 when daemon stopped. That you think?
