I don’t have the rgb version, but the same updated vented version.
It’s simply great, you can simply hear the difference and see it in temps and benchmark it. So it is simple you can measure temps and noise and fps and it all will be better with the jsaux backplate. There are great video reviews for cryobyte and bald sealion, they both put weeks of meassering and benchmark in to it and the result is identical and clear. In addition you can also change the thermal paste to Honeywell PTM7950.
In my case I can play cyberpunk, rd2, gta5 with maximum settings without hearing the fan and without overheating.
Two months ago I could play the first 3 games at max settings with 60fps
