AIO Cooler orientation

[brantleycmd]

Hey guys, working on my first build and ran into a small problem. I’m doing a sffpc on a mini ITX board, and didn’t really consider that when selecting my AIO water cooler. The problem is that if I set it up with the log oriented properly and the inlet/outlet coming out the bottom right, it impedes on a RAM slot. So the choices are run only 1 stick of RAM, or turn the block 90° so the hoses are either on the top or the bottom. Prefer the top personally. My question is will this hamper cooling performance? It shouldn’t if the closed water system is free of air right? I just don’t know if the outlet was on the very bottom right because it uses gravity or anything. Might be a silly question but I just want to be sure.

Where the tubes come out of the block on the CPU should have no measurable impact on performance. Go with what fits, then out of those options whatever helps you route the tubing most easily (and/or what looks good if you care)

Technically, if the radiator are mounted lower than the pump block it can affect performance since it'll pump some air which accumulates on the highest point of the system. Try to either mount the radiator higher than pump block or rotate the pump block 180° so the tubes will face down (assuming the motherboard will be mounted vertically).

The radiator will be mounted to the top of the case for that reason regardless. I’m more asking about the Pump block itself.

Then it's good, air will just accumulate in the radiator, it'll affect the performance in a very minor way.
