Any way to fix it? No warranty so ....
It's a very common occurrence in these units. You could carefully do a fanswap, or just live with it.
So it cant damage the components?
No, but it may decrease the fan's lifetime after some time.
Thanx. So replacing the fan could fix the problem?
The fan is the problem, so yes.
This is not my video but same problem... https://www.youtube.com/watch?v=MJ_-D31ZtPo doesnt look like its fan.
