My evga 1080 hybrid is on the way and right now I am trying to plan where I should place the radiator on my case. I plan on replacing 1 of my fans in my case and use a push pull config. Right now i am leaning towards replacing 1 of my front intake fans and put the radiator there.



I'm totally new at anything to do with water cooling. I've read that its best to place the radiator at a higher position then the GPU and also that the tubes be going into the bottom of the radiator. I'm thinking the best setup for me would be to replace the bottom front intake and putting the radiator there in a push pull config. Would that work?

I vote for lowest front intake (fan mounted as push so you can keep all 3 fans), it can't fit in the rear exhaust. The upper 2 fans can provide fresh direct air for the CPU cooler. With that set up all components will get fresh (cooler) air.

Thats what I was thinking of putting it. I'm just wondering if there is any downsides on having the radiator in that position? I've seen a lot of people using the radiator as an exhaust at the top or back of the case. I've read that having the radiator below the gpu is bad because of air pockets?

Without knowing what your case is and what speeds your run your case fans it's hard to know what is best. Just looking at your image it looks like your have gone crazy with 4x intakes and only 1 exhaust .. meaning case only has 1 exhaust fan's worth of airflow .. assuming your case has not top vents.

First thing I suggest is for you to look at "Ways to Better Cooling" linked in my sig. 1st post is index, click on topic to see it. 5th topic is a good place to start.

It is a fractal define design s...yes I do have 4x intakes with 1x exhaust..I figured 1x exhaust is good enough. I do have top vents but only the back top vent is open (the one closest to the exhaust) They are all ran by PWM depending on my CPU and GPU temps.

I've cut out the back vents as well so I believe I have plenty of exhaust. If you have any suggestions please feel free to recommend

These are also all 140mm fans xD. I did go a little overboard but I like the look to be honest and money isn't much of a factor. I hate watercooling but i want to try out the evga AIO this time for my GPU because of lower temps especially because during summer here the ambient temp can go really high as I don't have AC.

Cut out back vents There is only one vent in the back.
Do you really believe one vent hole with no grill can flow as much air as 4x vents with grills and filters flow? Personally |I would expect itt o be more like 2x vent holes with fans and no grills will flow about the same as 4x vents with grills and filters. But as long as system is running cool it's not a problem.

The back of Define S only has 1x vent and make-believe venting in PCIe slot covers so removing them will most likely improve case airflow around GPU.

You could put radiator in back but it would be using warmed air coming off of CPU cooler.

Bottom as exhaust but you would probably benefit from taller feet so there is a 30-40mm space between case bottom and surface it sets on.

Top middle or front of the 3 positions there. This will give you cool

Top middle or front of the 3 positions? What do you mean by that?

The back vent that I cut out looked pretty big to me and seemed like it would of been enough exhaust with the back top of my case opened. All the pcie slots I took off as well. I'm also not using a motherboard back plate. I do have my case on top of hockey pucks so it's more elevated for the intake !

. I've read your thread before and it has helped me out a lot!

Would putting the radiator the front bottom intake as a push pull not be very efficient? Right now I'm leaning towards it being the best but I see a lot of people using gpu radiators as an exhaust at the back or the top. I've read having the radiator below the GPU can cause problems with the tubing.
