Novatech A15 1.0 - Overheating

Hi folks, my partner’s laptop overheats quite quickly and I intend to open it up to clean out the dust from the fan and heatsink as I have done before with an Acer laptop.

Before I do, I’d like to have any tips from other users who’ve done this already.

I’d like to know what I’m likely to find when I take off the back panel.
