Hi everyone.

My friend has a Lenovo Legion 5 laptop where one of the laptop fans is defective. It basically stopped spinning, but every 3 seconds it will start spinning for like 0.5 seconds with a loud buzzing sound then it will stop spinning again. I found a Reddit thread where another person faced the exact same issue and they were suggesting that the fan bearing is off and should get the fan replaced.

My warranty is over including the extensions so my only option is to get it repaired and/or replace the fan.

I went to Lenovo's official support site, reached out to their live chat and was given a quotation for the fan part and it was almost RM300 just for the fan alone.

Is replacing the fan the only way or what are my other options?

What I meant by other options as in buying elsewhere rather than paying almost RM300 through authorised repair provider. Maybe use a different fan like you've mentioned that may cost only RM50 a piece.

Here are some images of the fan, Lenovo named it 'System FAN 81Y6':




I also had a look through AliExpress using the part number and still costs >RM150+.

Doesn't really look the same as the above. May I know also why do you suggest to change both fans?

This one's part number is 5F10S13917 while my laptop fan's part number is 5F10S13914

Though the shop mentions my laptop's model number correctly, is it compatible?

In addition they're definitely not exactly 100% the same, like the picture from Aliexpress has 1 circle/dot in the center of the fan, while my fan has 3 dots arranged in a triangle in the center of the fan:
