How many loops????

[lazduc]

Cooling 2 4870x2 and i7920. danger den blocks,1/2in tygon tube, gtx black ice 480 w/4 120mm fans, p6t deluxe mb, coolmaster haf 932 case, enermax 1kw ps, eheim 1260 120v pump, laing d5. Should I have 3 loops, one for each vid card and one for the cpu? Reason for the 120v pump is to not load the 12v rails as the case has 4 big 12v fans. I have the case fans connected to the mother board but was thinking of just wireing to the ps 12v rail. I could use the 12v pump but do not know if it will supply enough umph to push enough water through 3 or 2 loops. I could use just the 12v pump to cool the cpu as I have also another radiator..black ice pro 120.I could just use it in another separate loop by itself. I know it would be an overkill I think?? I am concerned about the video cards having two gpu's and going from one to the other in one loop and not having a loop for each card. What do you think???
Thanks for your timely response.

IMHO I would say 2 loops would be plenty. One for the CPU and the other for video cards. You should get good flow and good temps for the CPu and both of the video cards that way.

A popular DC pump for WC is only 18 or so watts. Basically nothing. AC is more of a pain, you'll need an expensive relay switching card to turn it off/on when you power up the PC. The D5 vario or DDC 3.2 also known as the 355 with a quality aftermarket top is less heat dump into the loop that the Ehiem pump. Stick with the 12VDC pumps.

Yea, two loops for sure. A 120.2 size for the CPU at a minimum, depends on how hard you push it and ambient temps. You'll need a 120.3 at a min for the GPUs, should be okay as long as you don't volt mod etc.

Why that rad? It needs high RPM (LOUD) fans to work properly. The Thermochill, fesser, or XSPC new version are made for quiet fans and work as well.

Or the ol' Swiftech MCR series. Very good rads and they work great with meduim fans, and when your not loading the CPU/GPU, fan control them to low speed.

Your choice on the rad, but many regret the screaming expensive fans they have to use when good fans for the other rads are $5-7 each, not $15-25 each.

And you want lots of great input from many experianced WC? Here ya go.
