I'm assuming you're intaking so bear with me here...
You might move your setup up to the highest point and then check the temps after running for a bit. Because you're just over the top of your GPU config and intaking their blowoff right back into the system.
Also IMHO the orientation of your Rad is just fine. The only performance increase you would see would be roughly -1c. While that may seem like alot especially with other modifications. It's also my belief that with the air in the system that flipping the Rad would promote recycling that air back through the pump. This is not good for any liquid pump. These types of pumps unless they have sealed bearings, need liquid to lubricate them. The H50 to my knowledge of bearings does not have sealed units in the pump. If they did the overall pump would be much bigger.
Now I would also point out that the system comes with a 2 year warranty and that lapping it will not void it. So one could mount it in any configuration they choose. Personally I mounted mine on the ceiling of my case as exhaust. No chance air recirculates back into the pump and against the advice of Jeff(Corsair Tech in the Vid) and Corsair.
With an ambient of roughly 72F I'm running 31c today.

does the orientation matter for the h50?
do the tube on the bottom decrease performance? would i notice a difference if i turned the H50 over so tubes are coming out the top?
