Or Dual DDC-1Ts'?
I think it's all relative really.. It depends on how big your loop is and how many restrictions by what you can afford and whether your billfold can weather the storm.
Two DDC 1T with EK Dual DDC v2 top alone is about $115. That's the cheapest you're gonna get off with.
Dual 35x and same top you're looking at $165 or more
Dual D5 and EK Dual D5 top you're looking at better than $200
And that's before you add dress up kits for any of them.
But really at this point only Dual D5 is more for blingage factor imho. They are reliable but they damned well better be at the higher price and lets face it we're water coolers price really isn't a concern. Not even to guys like me who had to piecemeal everything together. Some of us get lucky with good friends to help out, some of us pay whatever the cost will be and chalk it up as eye candy.
My personal thought here is go cheapest because 2 pumps should handle most anything you throw at them. If they can't you have a blockage somewhars in the loop. lol
Cheers for the reply Ceaddarman. Will be originally be cooling a 3820 (Waiting for IB-E), dual 7970's (with a mind of going triple 8970's when they ship), with 480 and 360 rads, so will I need two pumps to maintain a decent flowrate?
