First time watercooling, planning tubing.

post #1 of 4
Thread Starter 
I'm going to be doing a new i7 build, and I'd like to try my hand at water cooling.
I'm going to have blocks on a 950, and two geforce 470s. It's important that this all fit in a midtower, as I'm in the military and move around a lot, so I've selected the cm 690 II advanced because it can hold 2 240x120mm radiators inside without an unsightly radbox.
I've been looking at a koolance 980 for the pump because it's small and I like the temp display. So right off the bat, will that be adequate?
I'd like to know if my loop is good (I'm a bit concerned about having one gpu after another, will the second one get too hot?) as well as get a rough estimate of temps given the hardware and size of the radiators. Before I drop $400 on a water cooling setup, the obvious question is "is it worth it?" or would I be just as good leaving the stock fans on the graphics cards and getting a decent aftermarket heatsink for the cpu?

If you can fit an RX360 rad in there that would be all you need.

As for the one GPU after another these are my temps under load



I'm on one RX360, EK Supreme HF Copper, 2x 470's with EK Nickel blocks, XSPC res and MCP 655 pump.

I assume with the 2 rads you'll be fine since the water will be cooled after the GPU's and again before the CPU.

Wow, those are really great temps for load. Alright, good to know, this alleviates some of my anxiety, thanks for the info.

Watercooling is totally worth it! At 1.0 GPM of flow (most loops have more) it takes 260w of heat to raise the water 1C. Considering a 470 puts out just around 260w, the second card will be 1C warmer than the first.

Also, if you have that lower radiator in the loop as well your load temperatures will be about 5C cooler than AdvanSuper's.
