![]() Only very few specific HP models (8530w, 8740w) featuring SMSC EMC2103/EMC2113 controllers, some older ENVY 15/17) Some DELL machines might have problems using fan control DELL - many models supported, but fan control limited to 3 levels only. Alienware - all current models should be supported, but there are limitations based on model and fan control mode (EC support disabled/enabled) Last edited by quert April 7th, 2016 at 06:55 PM.Fan Control is not an official HWiNFO feature and there are currently only very few specific machines supported: I have chceked this on BIOS'es: A11, A09, A08 It seems that it could controll and read fan speed, but it is not implemented (lm-sensors site seems to be down time)ĭoes anyone have and idea how to tackle this edit It seems that dell-smm-hwmon could be not used if there was driver for ITE ITE8512E/F/G as sensor-detect finds it. But the catch is that without dell-smm-hwmon I get no pwm control device for fan so, cannot read or change fan speed. I narrowed it down to dell-smm-hwmon kernel module and after blacklisting, polling sensors (with sensors or xsensors) works normally. The same issue seems to be with i8kutils - when run, polling/writing hwmon pwm and input from speed makes system unworkable. I discovered this hard way when tried to run xsensors and barely could shut it down as there is no other activity during this pauses and xsensors polls sensors quite often. ![]() It seems that there is some problem as whenever any programm was reading/writing pwm/speed laptop hangs for 1-5 seconds. When used pwmconfig controls fan speed via hwmon device and reads/writes speed. I tried fancontrol/pwmconfig and i8kutils. I had no issues with wmi and function keys, bluetooth and wireless, graphics.īut one thing that I wanted to tweak was fan speed. During last week I have tried to install Xubuntu 14.04 LTS and Ubuntu Mate 15.04 on my Dell Studio 1537. ![]()
