Fan never turns off - Macbook

pinksheep · 2016-01-05 00:41:25

I have tried both mbpfan and macfanctld and neither of them seem to be working properly for me.

I have the understanding that below the "low temp" setting in the configuration file, the fan should be completely off. However, it never turns off - its always at 2000rpm (even if I set the low temp value lower). This leads me to believe that either the drivers are not receiving the proper temperature values, or I'm not properly activating the drivers, and some other backup driver is being used somehow.

Here is the output of my lm-sensors command:

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +32.0°C (high = +100.0°C, crit = +100.0°C)
Core 0: +31.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +30.0°C (high = +100.0°C, crit = +100.0°C)

Th1H: +26.2°C
Ts0P: +21.2°C
Ts0S: +23.2°C
Ts1S: +22.5°C

It's strange to me that the "min" rpm is reported as 1299, even though it is set to 2000 in the config file. But when I type:

sudo systemctl stop mbpfan

The fan turns off - so I believe the driver is activated.

I would love to solve this to save battery, it annoys me when the fan is always spinning. Thank you for any advice you guys have!

Hey, what model macbook do you have? I don't have the fan problem, but I do have a massive heat issue over here. I've tried laptop-tools, TLP, I run the fan service. I've checked my interrupts for ACPI storms. etc

Can you show me the output of: "grep -r . /sys/firmware/acpi/interrupts/"

OP hasn't been here in almost two years. They either solved their problem or moved on. Please don't necrobump, and use code tags in the future.
