Then what do you call someone that buys a 2400 dollar videocard, does very little tuning?
You can't expect PC parts to be completely plug in play unless its a prebuilt, and even then we saw how poorly prebuilts are.
Sorry but i just can't shake my head at this.
Its a true repeat of Starcarft2 all over again which concluded at "IDIOTS"
its the rear VRAM on the 3090.
Im 90% sure it has to be that, as i did have issues with it, as well many many others.
The solution to it was replace the stock pads, put a fan.

That kept the rear vrams from skyrockting to 90C + and keeping them nice and cool at around 70C.
Again... its something which should of been discovered in the tuning phase.
If your new, you really need to have people help you TUNE the thing to keep it in check.
