..... When was the last time you opened up your waterblocks? A bit of scaling over the surface and you basically have a insulating film over your heatsink.
Keep in mind, good flow does not mean you would inherently have clean blocks. Gunked up blocks can mess up flow, but if material were to scale over the surface it might not mess it up that much.
His coolgate rad has a .3PSI pressure drop at 1gpm

It can really only be a problem with contact between the blocks and the cards to cause temps that high. Usually when graphics card blocks are tested, even a very low flow rate only causes a few degrees temperature increase.
, the raystorm has a .7PSI drop at 1gpm.
So if the Kamodo has a 1.5psi drop at 1GPM
we're looking at an estimated 4.3PSI pressure drop. That's pushing upwards of what a D5 with stock top can handle.
Whether that was indeed the problem or not, it would have been wise to upgrade regardless.
I would make sure your fans are getting proper airflow because, as PCilliterate said, with the orientation visual analysis suggests it seems like you may be having some weird air flow issues. Though it's kind of hard for me to tell your airflow by the picture linked. If you haven't opened up your blocks in a while, I'd check that too.Edited by ZytheEKS - 8/2/13 at 3:12am
