Re: Lenova Y50-70 Fan problem

Welcome to the Forums Artadj.


Some reasons for fan noise:


Fan is very loud when the CPU load increases.  Possible causes could be dried lubrication in the fan, worn bearings, or just a dust build up. Hence try cleaning the fan once.


CPU is running very hot. Applications like tp fan control can tell you the temperature of the CPU and GPU temps above 80C under load are high, and above 90C suggest that the fan or heatsink could be clogged.


Ambient temperature should be taken into consideration. PC will shut down during increased loads on the CPU or GPU. This happens when the CPU or GPU overheats - typically above 95C. It’s a protective measure taken as to not fry your CPU.


  1. If you open up your task manager, do you see any processes that are consuming high percentages of CPU?

2.Also run virus scan with the latest virus definitions and check for no viruses or malware. 


3.You should also install a temp monitoring program and post what your temps are.


Update us how it goes.
