If I'm correct and it appears you only have one "two fan" radiator cooling both the GPU and CPU then I'd say you have too much thermal load for that radiator and you either need to increase it to the larger model or add a second radiator in place of a bank of fans.  Of course that will require more plumbing...

Never mind, I see it now... 
You still need to look hard at air flow volumes and direction to make sure that you are moving air as expected.  I've seen people build systems with no thought for which way a fan is moving air and end up with a thermal mess because they've created dead spots, or back pressure that limits flow through a radiator etc...

It is hidden a bit. It is a 360mm and a 240mm radiator. I have all fans exhausting except 3 intakes at the front. I figured it would be best to push air out from the radiators to get the heat out. Maybe I could put the rear fan as a inlet fan also.
