I have been looking for a possible solution myself and could not find anything. The only thing we can do is to crack the BIOS of Lenovo and work out a manual fan control ourselves - all other software I found online did not work at all with this Laptop! The Lenovo Legion Brand (y540) and those that do not have manual fan control speed are in case of thermal management "crack machines" - thermals and performance are going up and down like a roller coaster. If anyone finds out something I am all ears. 

The only thing I can suggest to you Priyansh Singh is to undervolt your CPU. That may help with thermals but it will still act like a roller coaster.
