Z50-70 fan issue

Hello guys

 

I have an annoying problem with my CPU fan.

 

When i start the machine the CPU fan is running at max speed for a few sec after this it's stops and never turn back again. If i restart the machine it's doing the same thing.

 

I tried BIOS update and win update, but nothing.

 

What could be the problem ?

Re: Z50-70 fan issue

Hello CrB1337!

 

During startup a lot of CPU time is used. Which may cause the CPU to heat up. This is why the fan will run at full speed and make a loud noise until it gets into windows, this is common.

 

If fan runs at a higher than expected speed, you can check this article: https://support.lenovo.com/us/en/solutions/ht077046.
