So my Laptop CPU fan is not working, Acer Sense app is showing 0 RPM. I confirm the same thing by looking at the Fan. GPU fan was working Normally. I thought this problem was due to dust build up in the Fan. So i took my laptop to the nearest private repair center (as my laptop is out of warranty and nearest acer service center was 50km away). The repair guy cleaned the fun and heat sink but it didn't worked, rather it created a problem, now after i completely shutdown my laptop ( not sleep or Hibernation) after sometimes the GPU fans starts Spinning at Max speed.

As due to the current Corona situation, I'm unable to Visit the Acer service center, but I'm really worried about my laptop, i haven't updated my driver or BIOS, the problem started after the cleaning of Fan.the repair guy said that this is due to faulty Fan, and replacing it will solves the issue. I'm concerned that he might have demanded some other part, like the Motherboard?? Though laptop is starting and working fine.

Please help me ASAP, the worry is literally Killing me. 
Also i would like to known the estimate cost of repair.
Please Help me..!
Thank you.
