Lenovo Legion 5P-15IMH05H: coil whine and constantly-running fan

2020-10-18, 19:43 PM

I recently bought this laptop, but I noticed 2 things. First is loud coil whine when computer is on. Second thing is fans run constantly even if I turn on ultra quiet mode in bios. That coil whine stops (not completely, just not that loud) only when I change Processor power management to 98% and lower in maximum state. 

When I turn on laptop coil whine gets really loud on Lenovo logo.

 

After not even month of using I've been trying to find solutions and tried probably everything to solve this. I Didn't expect to spend so much time tuning my laptop after purchase. 

Is this defective laptop or I just have to get used to it?

I have the same model with zero whine. Seems like you have some kind of hardware issue.

I am also attaching sound that I recorded during start up of my laptop. It gets stronger after Lenovo logo shows up (in attached file it's after 18 seconds). This strong whining happens always when I have attached external mouse or when I'm browsing web and scrolling. After taking processor power down to 98% or less, whining stops.
