I love this waterblock. Looks amazing. Have any pictures of your whole build?
Not surprised it fits like a glove, 99% the same card really.
Did you run the card on air at all? Any coil-whine from it? If so...does fitting the block improve / change that situation at all?
One thing putting me off doing a custom loop now is the amount my card whines. No point going full WC to quiet down the PC if I am still stuck with the whine!
Infact.... the fans at least mask it somewhat.
