Bigwater 745
I have the Bigwater 745 cooling an overclocked D805. The pump and the radiators seem very effective, though I am not too sure about the waterblock. It just does not seem to be able to get the heat away into the water. To be fair this is my first attempt at water cooling, os it might just be me, but I have tried reseating the water block using artic silver and also various different orientations of the water block, but temperatures will still climbt to over 50 degrees c when D805 is clocked at 4GHz. I am comparing it to the Arctic Freezer Pro, which acheved similar temperatures. The water leaving the block never gets above 35 degrees and the water entering is a room temp, approx 22 degrees, so I think perhaps the waterblock is perhaps at fault or possibly the processor or heat spreader. It would be interesting if anyone has any ideas. Other than that I can report that the Bigwater is very quest, even with the external twin 120 rad. Nice beginners kit, not sure about water block.
