Its a 500W GPU as I said earlier, the 295x2. I suppose if I am cooling with water, I prefer water cooled temps and not what I could get on air. As I said that rad was almost hot to the touch.
Temps with a properly radded loop were around 55C load (by proper I have 5x120mm worth of radiator, one was double thick rad - also cooled a CPU). My rads, while warmer than the air, were not close to being hot to the touch. Again, open air so it was getting ambient air. I think we disagree on what is 'enough'. I don't find air temperatures 'enough' when cooling with water... no point... too high of delta's, and I am not a fan of 40C+ water.
