If just 1 295x2 it is "ok", the cards get very hot and most likely will throttle if you use powertune.
The best setting is to use +25 on slave GPU (second gpu) and to control middle fan to cool the VRM better.
If you use normal powertune there is a lot of chance that it will throttle on the most expensive algorithms..
You can't use a card just under it, or it will get too hot and it will throttle.
I modded my cooling. I have a 240MM radiator with 2 fans to cool the beast. The best is to go full waterblock if you use many cards
