Impeller stuck in AIO CPU cooler
I'm trying to fix a Cooler Master Nepton 120XL (AIO) for a friend, where the impeller seems to be stuck.
It has been getting worse over time, it went from running fine to running slowly (The PC would shutdown because of heat when gaming), and now it doesn't run at all.
If I try to rotate it by hand it goes really tight.
When I power it up the LED gets on but nothing is moving. Sometimes it makes a kind of constant beep tone, so maybe the circuit isn't damaged.
Is there any way I can get it 'free' without damaging the motor behind the circuit?
