How high are you runing your voltage & O/C Maxxx?

Point of that question is this. With higher voltage & overclocks the better cooling of the more advanced block would be of increased value. Will extend your cards life while giving higher performance as well.

And while you saw no gain, your card may be pretty well maxed out regardless of a cooling increase 10X as great. If I recall right you're not thrilled with the O/Cing of your card, which tends to support my point regarding it being your limit, not the cooling.

While increasing the temps by increasing water temps would offer some indications of the cards tolerance of temp variation at THAT setting, it's not the same as increasing the overclock and temps generated within the GPU. I'm sorry, I wouldn't trust that as really proof of anything other than how the card reacts to temps being increased from outside it.

As to the Iwaki pump, I can arrange that, as can you. My interest in this is two fold, first and of greatest importance is what I can learn regarding how to best tweak my own rig. Secondary is the improtance to general usage.

My comment towards Cathar was in jest, I know he's far to busy right now to be spending time on the Hydra.

Though if Cathar does develop a GPU design in time I will most surely be interested in it. Cathar has never brought out a new block design that didn't push back the limits on cooling/performance. Nor do I think he'd disregard a GPU blocks head loss. Were he to design a GPU block with jets of the style of the Cascade/Storm I'm sure he'd draw from the SS Cascade's jet size/pattern. Look at the flow rate the SS had, hardly to restrictive & if he tweaked it a bit for more flow as the goal with nearly the same temps, even better. I'm not suggesting a silver GPU here, just use of the SS's impingement pattern.

As heat output of next gen cards comes about this will be a increasing need. Give vid cards just 2 more generations and it's going to get interesting.

I know some think TEC is the answer to this, but I'm not the only one who won't use them. There is going to be a large market segment for new and advanced GPU blocks. Blocks that offer better cooling, and without prohibative pressure drop.

EDIT:

The Storm's increase in performance vs the Cascade, as far as O/Cing goes is most likly limited. But it does cool a bit better.
