Oh yeah, that makes sense. I always go for super, super deep cases.Problem for alot of folks is the 30 series cards are already almost comically long, the powerlink puts it off the end of the board instead of behind it.
Even in the example above you couldnt fit a powerlink in that sliver of space, but the 180 degree connectors fit.
Well the front side of the card has the cooler so my view is the hot vram is on the backside of the card. Anyways the EVGA pads were better than the ones I installed. It is more likely the original was 1.5mm pads while I put thicker ones, 2mm on, which is my thought or the rating of the pads is incorrect. Once I get the CPU water cooler, I will install the heatsinks on the backside for the vram and that will tell clearly if I need to do the front side of the card.^ That pad mod to the 3090 is a little perplexing, no offense. Doing only the back VRAM modules on a 3090, I'm not surprised TJ temp actually went up.
The backplate is not a heatsink, and most of the benefit from these 2mm pad swaps comes from doing the front VRAM modules since EVGA stock pads don't transfer heat as well as the thermalright pads.
I haven't needed to do a 3090 yet, but if that GPU were mine I would've swapped only front 2mm pads and tested, and then maybe done back modules with low expectations, and then only if I also had actual airflow across the backplate for it to even matter.
3090 is the wrong card for that particular case and CPU cooler setup while also trying to do memory OC intensive mining, and new pads can't perform miracles.
