I currently have a coolermaster eisberg 120l and want to expand to a full watercooling loop, is the 400L/hr pump in the eisberg cpu block and the 75ml or so reservoir in the block enough for the following loop in a TJ08e case? cpu block (eisberg pump and res) - 180mm radiator - 120mm radiator - gpu block x2 - 120mm radiator - back to cpu block
It's not the flow rate that's particularly important in this case it's the head pressure. I think it should just about work with the additional 2 GPU blocks but you may not necessarily get the best temperatures. I'd try it and if you're happy with the temps then stick with it, if not get another pump.
As above, you need the pressure more than the flow rate. Try it, see what it's like, and if you're unhappy, change the pump. However, don't expect absolutely massive temperature drops.
