Glad to see someone else notice...
WHY DO THEY HAVE SUCH TERRIBLE COOLING SOLUTION!!
I have to design my rigs in closed boxes with fans in back and front to make a all air beeing pulled out and away from the hardware.
This is really frustratingto me.
Ive seen a few models where they use the good old nvidia solution with 1 single exhaust in the butt... i love that.
This blow-hot-air-randomly-all-around is really really really annoying.
Its a good cooling solution for 99% of use cases (1 gpu per pc). I can see its good because with 1 gpu inside the case the temps are low and the noise is very low. But like you said, for us miners, the blower coolers are great and all my 290's have one. Well, they are great unless they are in your living room. They sound like jet engines
I'm doing the same as you are. 7 GPU's separated by cardboard to force air on one direction.
