A question about Radiator Placement?

post #1 of 4
Thread Starter 
I bought an Antec 1200 full tower. The two rear 120mm exhaust fans are at the top of the case and there would be almost no room to mount a Radiator with the tube inlets flowing through the top of the Radiator. Will mounting the Radiator upside down, the inlet/ outlet at the bottom, cause a drop in pressure or loss of performance? Is it better to mount two single Radiators sideways and then link them together? The system will be gravity fed from a tank sitting on top of the case.

I noticed that too with this case. After some thinking, I came to the conclusion that it's all the same.

If the inlet was upside down, then it would have to fight gravity going up through the rad, but it would have gravity help push the water down through the outlet. It's the opposite if it was right side up. Going into the inlet, gravity would help push it down then it would have to fight gravity pushing water through the outlet.

So, to me, it makes no real difference, but you should wait for input from others.

There will be no performance difference. Lots of people, I included, mount rads upside down.

I usually mount mine barbs down to. I would make the rad easy to remove so that you can shake it while your bleeding, that will speed up bleed time a lot.
