Hmm. It does look as if the fan on the card isn't designed to mainly blow the heat out of the back of the case (like a blower). I have a H440 case and was hoping to dump just about all air straight out of the case. (I have a top mounted kraken x61 on my i7-4790K.)
Or perhaps it won't matter much, as most of the heat should be taken care of by the AIO?
