I've just installed Ubuntu 14.04 on my new T440s, and it seems the fan starts working at full speed from time to time, I've read in several places that this causes the fan to be noisy and generally not good for the computer/fan.

I've read many post and couldn't decide the next action, should i control the fan speed, do i need to configure something related to computer's temperature, or should i return to windows, and download Lenovo power-management tool?

Please also take a look into the BIOS/UEFI Setup Menu. Maybe there are settings which can influence the fan control. –  DiableNoir May 27 at 10:51

The fan should work at full speed from time to time. When your machine gets hot, the fan will run at top speed to cool it down again. This is a Good Thing® and you should not try to change it.

If you feel that it is happening too often, that it occurs even when the machine is not hot, you might need to tweak the default temperature thresholds. There is a nice little program, ThinkPad Fan Control that lets you do that for ThinkPads.

You should also read the How to control fan speed page on http://thinkwiki.org which is the site for Linux on ThinkPads.

yes, but I have read on Lenovo site ,that running on other OS than windows, without fan control can cause noises on the fan that I have... –  user271946 May 7 at 21:30
