295X2 water cooled - one GPU running 12C hotter than other.

I've just hooked my 295X2 with EK water block up to my first water cooling loop, and all seemed well, except that when I started working the card hard, the first GPU is getting up to around 75C, while the second GPU is around 62C. Could this be incorrect fitment of the block, or maybe something else?

Not to be rude but I have water-cooled those cards in the past, Why are you hitting 62c.


What is the loop?

I feel you may have bad contact between the block and the card.

I didn't fit the block myself, so feel free to savage that. The loop only includes a 120mm EK rad and an EK DCP 2.2 pump and bolt on reservoir (only the graphics card is in the loop). I know the 120 is pretty small but it's much thicker than the 120mm rad that the 295 comes with stock. Could be the limiting factor?

I tried removing the block and wiggling it around. Some bubbles come out and gradually worked around to the res, but after refitting it, the temps are still the same: 74C and throttling on one GPU; 65C on the other (while mining).
