My Ek x1900 water block...

his OC isn't that high.
mine is 690/800 for my everyday game speed.
I've never seen mine go above about 55C.
I've also been testing the hell out of my card lately, cause I am messing with a Accelero X2, and I use Systool to create temp logs of my PCB, Core and Vreg, and in all my temp logs of the Vreg, it's never went above 55C.

odd my x1900xt is showing 52c stock speeds. I cant see yours only going up 3c when overclocking that much. but maybe its not that effected by core and memory freqency changes ? im no expert just an observation.
