Mentions that Intel processors have the chip in the middle of the package, while AMD processors are spread around the package in multiple chips, so it’s more important to spread your thermal paste well. The result was that, on a Noctua CPU cooler, the Tech Ingredients paste was equivalent to the Noctua NT-H2 thermal paste. Maybe slightly more consistent, but not detectably better or worse.

Ingenious design for their thermal radiator/heat exchanger/passive low temperature solar collector panel: aluminum channels bonded with epoxy, plus foam blocks to reduce the water volume, and aluminum sheets for the faces. Polyethylene Glad film prevents convective cooling, and he airbrushes a white high-emissivity coating (barium sulfate as specified in a later video, probably nanoparticles of varied sizes with a bit of binder) onto the aluminum. Propylene glycol prevents his water coolant from freezing. He got cooling to -7.6° in an 0.5° environment. #cooling #energy #video
