Any experience stacking 30xx 40xx founders cards ?

Hi, giving the prices of GPUs I'm considering buying a second founders edition that I'll put near my 3080ti FE. Anyone has experience stacking them? Would the overheat?
Cheers.

Thanks, I've check that website several times. The thing is that flounders edition are a rare specimen, so I don't know how would they perform being staked.
