Yes, a challenge.
My 170 had a custom liquid cooled heatsink with an external block with a 360mm radiator. I could easily cool 250W from the 2080S (shunt moded) and 180+ from the 10900K@5Ghz without any problems or noise.
In the case of the GM6PX8, we are trapped - there is very little room for modifications.
In addition, the side radiators are made of aluminum instead of copper, which is a terrible savings.
Thin fans make an annoying sound at maximum speed.
The water cooling loop only works on the GPU, the CPU is practically left without additional cooling.
At the moment I am in the process of selecting the maximum UV values, overclocking the RAM, and am really looking forward to the opportunity to purchase a new heatsink from the 2024 model.
