I was cleaning my laptops fans and accidently (and stupidly) broke a few of the blades (see image - red is where the blades are missing).

They were apparently too loose and fell off one after the other during some heavy fan action.

Is this something I should be worried about? It doesn't sound much different than before, and the cooling is the same as before. It's a Lenovo Legion 5 if it's of any interest.

I have for sure learned to be way more gentle, and would like this to focus more on whether or not I should do something about it. I thought about glueing the blades back on, but am not sure if that is needed.

Thanks for your help!
 
The only difference is a little louder and vibrates when angled on my laptop cooling stand. On flat surface it doesn't vibrate any different than before.
 
Hello

I would think if you keep the vibration down as much as possible it should be ok until and if you get a replacement.
 
the fan would now be unbalanced and I would have thought the noise and vibration would have increased a fair bit.
I'd be looking at a replacement.
if the noise and vibration isn't too bad, you could limp along as is but eventually you'll be killing the bearing.

you could rebalance it by breaking off the blades on the opposite side!!! :cool:
(but there be dragons)
 
Or you could use a piece of metal securely fasten down and that might balance the fan.. Kinda like balancing a car tire with weights .
