Need help with loop and fan set up (CM 690 II)

post #1 of 4
Thread Starter 
I recently purchased a 670 and will be putting it on water and I wanted to get your opinions on how I have my loop set up. I have two radiators, RS 240 and RX240, which you can not see in the picture below. Each radiator will have two Ap15 in a push configuration and one Ap15 to exhaust the hot air in the back. This will definitely be a positive pressure case and there are two additional side vents once everything is all closed up for extra air to escape. I have one 140mm fan that came with the case that I can't decide on whether to point outwards or to point inwards. I don't think I've ever seen someone with a case where the front fan blows out, but I am thinking I might have to do this. What are your opinions?

Also, does the loop look right or should I change anything on the way it flows?

Please ignore the wiring at the moment. I've been changing around hardware.

I don't see any glaring issues with your proposed new loop, but I do see something I'd change in your current loop. You're using a Y connector for a drain line, and that's fine except for the fact that you've got it set up the wrong way. That's a serious angle going from the CPU block back to the res, and your flow would be better if you flipped it around like this:

cpu
.........>- res
drain

I know I didn't plan it out. I realized that after I had already leak tested it a few months back and its been bugging me since.

What do you think I should do with the 140mm? Make it an intake or or exhaust?

with ur picture setted up, u will get hotter temps, due to too much ingoing air, but 1 fan for exhausting,u will creat a hot tornado inside ur case.

i owned that case 2 years ago, it's a dame nice Mid size case.
here is my advice.

RS 240 up top with either push or pull, push if u can fit it with minior mod.
RX 240 button push from button,works out the best, pushing fresh air outside the case .
rear side, u can also try to fit a 120 thin one if u want it to, but it's really not neccesory.
140MM intake fan.
so that u will get ingoing-> outgoing balance out. good luck.
