Hi,
Are you running them on a seperate loop, or with cpu?
What are your load temps for gpu and cpu?
If cpu is on the same loop, what rad and fans are you using?
I'm wondering which fans to get, as I want quiet ones, that can be ramped up. The Nexus fans seem to be good, though not quite as fast @ 12v as the Yate Loons.
Those blocks are quite expensive, for 2 block it would cost loads, my major concern for that kind of expenditure would be that they may not fit future cards.
Sorry for all the questions, curious atm as you know I'm going over to water cooling soon.
Regards
Raja
