I use 6 Cape Cora tubes, instead of using the lousy and ugly looking T connectors and soft pipes, I made my own Hard metal tube and T junctions. I kept all T junctions for structural reasons then I have blocked the flow so that it is going through all elements equally.
The space between them and the fact that the water has to flow trough all the elements I think makes it keep good temps on my system.
I tought that attaching the pump right on the elements would make the pump noise more annoying but it didn't, the frequency of the EHEIM 104x do not amplify. The Water tank is located higher on the same element, the beauty of this system is that the bleeding is instant, as in no bleeding problems.
If it is needed one can easily replace this setup for a chiller.
The black setup is for the machine described in my signature. I often have problems with my video card showing 255C when it goes under 25C. The CPU stays in the 30 - 35C. My ambient is around 21C.
PS: The meter was to test the L versus non L flow and pressures, so don't mind them.
I use only the black one, the gray setup is for a friend who didn't want the pump inside the computer. I think that in the future I'll do it like that. keeps the computer cleaner.
