is wc really silent?

One loop can work fine, but generally the GPU will dump more heat into the loop and could limit your CPU overclock, and GPU's don't complain as much about warm temps as CPU's do. So if you're after a max CPU OC then it would probably be better to split the loops.

Biff , what about placing 2 rad on one loop. So 1 rad will be betwen the CPU and the GPU, I ask because it's something I will may be done soon

[biff]

The amount the water cools as it goes through the rad isn't that much at all, I think I recall reading it's only about a degree or two for a typical setup. So adding a second rad will certainly lower the loop temp as a whole but it won't 'isolate' the CPU from the heat dump of the GPU like some think it will. Usually the order the parts are placed in has little to no consequence on the performance of the loop, with the exception of wanting to place the pump input as close to the res as possible (if you're using one). Laying out the loop so it's short and neat is better than trying to follow a particular order of the parts.

I just have 3 fans on the triple Feser 360 rad plus 1 x140mm and 1x 230mm fans in the case. The loudest part is 655 pump, but it is not even on a supplied foam pad.

On Antec I have 5x S-Flexes (including one on CPU heatsink) + 200mm on the top.

Dual loops are not strictly necessary, generally they are only done to move high resistance blocks out of the loop to keep flow up. If you have a powerful pump one CPU and GPU are not going to mess with your setup so long as you use a relatively free flowing block. I would recommend a triple if you are doing both, a dual will almost surely be too much heat dump.

Thanks Biff it's really make sense. Anyway I have the place for 2 pump, and it will not make a big difference on the total price of the rig.

+1 for this post, although for high-restrictive blocks like Koolance 350 dual loop is valid option too.



I personally consider add single rad on the back, just because I have space. Here is my set up for now (GPU(s) are not cooled yet, as I'm still desiding between few CPU blocks):

[biff]

No problem. Just to restate others though, it isn't necessary to split the loops to get good performance, you just have the potential for better performance if you do but don't expect night and day differences.

[Bomberman07]

then I need a rad for each loop right?

[dataxpert]

It’s what I thought too before, but Biff make me realize than the CPU will be at same temps than the GPU.
