I did decommission the fans and heat sinks on all of my cards to check thermal paste as the MSI Gaming X were pre-owned. They have much bigger (Overall Thickness) heat sinks and have thinner fins designed horizontally so when the fans are on they blow out via the vents.
The Nvidia heat sinks are smaller (Overall thickness) but have thicker fins directed vertically which doesn’t make any logical sense because if they were in a PC housing the blowers would be blowing the hot hair around inside instead of out.
In terms of flow of air volumetric and velocity The MSI have bigger fans and have smaller outlets so at 30% fan rate I could feel it on my hand. On the NVidia the fans are smaller and the outlet has bigger holes and I could just about feel something coming out.
Yes, I’m a bit of a weirdo but then again that’s why I’m employed to analyse measurement uncertainties for fluid flow so it’s a win win to be in a niche job. I hate to think what I’d be doing with a liquid cooled graphics card I’d be using my work devices to measure the flowrates analysing flow profile, measuring the temperatures on different points for thermal dissipation and cooling efficiency. My boss would probably pay me to conduct the tests and then push the sales guys to visit the manufacturers to improve their quality standards
