Mi Notebook Pro fans replacement

[Ferdinand Olah]

Hi

No need to replace the fans. A friend of mine recommended a product for getting rid of the rattling noise, which worked wonders in my case.
It is lithium grease, that costs about 4 dollar a pound, you can buy it in any auto parts-, or DIY store. You have to apply a really tiny amount, where the arrow points to, then put the fan back in its place. And that’s it.

Been using it for about a month now and it is completely silent.

Thank you for your reply. I will try your technique (probably tomorrow). I guess I am a bit pessimistic about how long it will last though. It’s really quite a shame, that Xiaomi doesn’t make replacement parts for their most expensive machine widely available.

It will last, don’t worry. As for the fan that is rattling, it is not a faulty part whatsoever, notebook manufacturers just tend to spare with lubricants. Ff you could buy a brand new fan, that would still be rattling after 1-2-3-4 months of use. Our notebook has a magnetic levitation fan, there is no moving parts in it like bearings, so you just have to give the fans some extra padding in order to operate silently.

Thanks for this tip, is it still working?

Amazing, did you do both fans? Are the fans hard to disassemble and add the lithium grease too? Apart from an SSD upgrade I have not messed with much laptop hardware.

Yes, I applied lithium grease to both of the fans, I figured since I already opened up my laptop, might as well do both, not just the one that grinds. Not hard at all, if you’ve already removed the bottom plate, its only 4 additional screws on each side of the fan. The fan blade itself is held in place by magnets. Be careful to lift the fan perpendicular the the laptop and dont bend it.

 

Report back how it went!

@Ferdinand Olah

Should I use lithium grease that is sold in a tube or in a spray? Thanks !

[Ferdinand Olah]

I used lithium grease from a tube, you only have to apply a really small amount, like ‘tip-of-the-toothpick’ small.
