WC'd GTX680 Extreme Heat

[EtherealConstruct]

Hi guys,

I got my first watercooled loop up recently, and I thought everything was going fine, until I tried to play a game. The game has some bugs, so it might not be this, but the game was crashing my system after playing for only a very short time. I decided to download FurMark and GPU-Z to observe my temps under load. I was VERY (and unpleasantly) surprised to see that the GPU was getting to >100 degrees celsius under load. Something is very, very wrong here. Here are my specs:

i7 3930k (stock clocks/voltages) -> Heatkiller 3.0 block
GTX 680 (stock clocks/voltages) -> Heatkiller LT block
Cold Fusion Tube Res
MCP650
Swiftech Quad Radiator + 4x GT1450

No Leaks, cleaned out blocks before I installed them... CPU temps look fine....

Ideas for debug?? Thanks!

The first thing I would have done was check for gaps or mistakes installing GPU block.

Reseat your GPU block. Something isn't making contact where it should.
