My Gaming Notebook Ventilator RPM are decreasing

[6./ZG26_Klaus_Mann]

Hi,

I have an Acer Predator Helios 300 with 1.25TB SSD, 16GB DDR4, GTX1060 and an i7 with 3.8GHz. All in all it's a pretty good Machine.

For Ventilator Control I have the OEM Acer PredatorSense Software installed and for Gaming I generally set it to Max.

 

I used to get 6122RPM, then 6000, then 5882 and now I'm down to 5769. I do occassionally Vacuum on the Ventilator Inlet, which would spin them in Reverse, but always with a Shut Down PC. Have I done Damage or do cleaner Ventilators spin faster?

No matter  technology the electric motor have it would not take damage spinning the other way around. But if the fan is old it might simply be worn out or hair and dust is on its axle.

The Issue is that I don't know how to disconnect the Battery for disassembly. I have always been a Notebook Scrub and I am used to modifying them. but I don't know how the ones with fixed Batteries work.
