"How I did it: I just cut a whole in the top cover, put a copper block with thermal paste inside. An aluminium heatsink on top, balanced it with cardboard and tied it together with zip ties. done everybody can do this! No high budget needed like for overpriced Streacom, Akasa... Overpowered cooling denies cpu and gpu of reaching more than 63°C /145 °F Full HD Gaming medium/high settings 30-60 fps."
