Capillary action investigated and explained

"In this video, we're deep-diving on several important factors of how heatpipes work. For years, viewers have asked us if CPU cooler orientation matters, typically wondering whether a flat test bench was representative of a standard "vertical" orientation (e.g. in a PC case), often referencing gravity, despite the fact that capillary action can work in opposition to gravity. Some scientific research has shown, as noted in the video, that gravity and orientation or angle of heatpipes can affect performance, but that research is in use cases and deployments outside of computer hardware. We'll walk through heatpipe manufacturing, research from other industries (like aeronautics and space), internals and cross-sections of heatpipes, and more. This features the AMD Wraith stock cooler, Deepcool GamerStorm Assassin III cooler, and Noctua NH-D15 (with internals of a Thermaltake Contac 12)."

Steve sounds exceptionally drunk (or high...) at 0.5x playback speed, between his (possibly codec induced) slurring, repetition, and random pauses.

And...as expected, physics work and capillary action is witchcraft. ;)

He DOES like to hear himself talk. I turned it off after 10 minutes and the third or fourth or fifth time he referenced capillary action, gravity, atmosphere...

the video is based on Anecdotal evidence ... here's the simple answer to the Q, "does gravity effect CPU cooler heat pipe efficiency?"

"Celsia manufactures heat pipes in all shapes, sizes, and performance characteristics for use in its custom heat sink designs."
