My Lenovo laptop used to turn off its fan in Windows 7, this would save a lot of energy and battery would last maybe about 2 times more.
After upgrading to Windows 10 however it never turns off.
I wonder how can I fix it and what is the reason of this problem.
I've tried using dust removal of Lenovo energy management software, it speeds up fan for a while and in Windows 7, I would have silent fans afterwards but it's useless in Windows 10.
UPDATE
It was an Intel Graphic's driver bug and it's fixed now, if you're having this issue you need to update your Windows.

Maybe try this guy in advanced power settings? Windows 10 upgrade defaulted my power settings, and if you're on "high performance" IIRC it will be set to active.
I had the same problem using a Dell Latitude Core i7, after upgrading to Windows 10, the Fan was running continuously in high speed mode, very annoying, I just switched from Balance power option to Power Saver, Problem solved, the fan runs in low speed most of the time and only when processor is pushed to the limit it speeds up for short periods of time.
