Hi I use a MacBook Pro (beggining on 2011), tlp and mbpfan-git. On 3.14, the fans works OK and tlp-stat -t output something like this : --- TLP 0.5 -------------------------------------------- +++ Temperatures Fan speed = 2001 [/min] Temperature = 50°C Now, on 3.15, the temperature line in tlp-stat isn't present and the fans are at the minimum level (2000/min). It's strange because lm_sensors seems to work : applesmc-isa-0300 Adapter: ISA adapter Exhaust : 1999 RPM (min = 2000 RPM, max = 6200 RPM) TB0T: +39.8°C TB1T: +39.8°C TB2T: +37.8°C TC0C: +62.5°C TC0D: +63.5°C TC0E: +64.2°C TC0F: +64.8°C TC0J: +0.5°C TC0P: +60.5°C TC1C: +61.0°C TC2C: +61.0°C TCGC: +62.0°C TCSA: +63.0°C TCTD: -0.2°C TM0P: +50.0°C TM0S: +62.8°C TMBS: +0.0°C TP0P: +64.5°C TPCD: +74.0°C TW0P: -127.0°C Th1H: +51.2°C Ts0P: +36.0°C Ts0S: +48.5°C coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +71.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +71.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +65.0°C (high = +86.0°C, crit = +100.0°C) I looked in the kernel changelog, but I can't find anything relevant. Any idea ?
