Case ventilation

My question would be... what are your temperatures reading on your GPU? Based on your Member Configuration, your temps are acceptable. If they are acceptable, than there is nothing to worry about. You want hot air being blown out the back... better than staying in the case.

If you temps aren't good... three quick suggestions.

1.) Use EVGA's Precision tool to manually set your GPU fan speed to 80% or so. I did that on my first slot EVGA 260 Core 216 and got about a 10 degree temp. drop at idle and load. Now both cards run at the same temp.

2.) Remove all of your un-used expansion slot covers to allow more air to flow out the back.

3.) Depending on where you have your HDD's in the case... I would recommend moving them so the front fan blows air in to the GPU's without hitting the HDD. Based on your case, I would say install the HDD's in the bottom section of the case.

Always check your cable management to make sure your cables are not blocking your air flow, that is why it is always good if possible to run them behind the MOBO tray.

I'd be more worried if the air was cool! Since it is warm, that means it is expelling heat, which is a good thing. So, like Temco34 says, don't be worried just about hot air, check the temperatures of your components. If they're okay, then everything is working the way it should.

Can the power supply overheat though draw all that extra heat through it and out the back? the bottom of the case is like a small heater you can feel the heat emitting 6 inches always. normal?
