Mini ITX CPU + GPU Loop, minimum Rad Recommended? Possible?

[Humble Bee]

As the title suggests I am think of doing a new PC Build. I currently have a Custom water-loop in my desktop (Fractal Arc Midi) With a 60mm EK 240 RAD in push pull taking care of a 2600k (1.375v) keeping temps at 56 celcius under load with a 21 celcius ambient temp in my room.

 

After it seems that Intel finally have something decent behind their heat-spreaders now with devils canyon I am thinking of doing a mini-itx build with the i7 4790k and a EVGA 6GB GTX780. I plan on water-cooling the GPU and CPU if possible, but I am limited to RAD compatibility as using a mini-itx case (Bitfenix phenom).

 

I chose this case as I can keep my beefy 60mm EK 240 in the roof as there is a lot of clearance for top RAD support in this case (Can get thicker RAD with just Push if that is recommended). And I believe I could get a thick 140mm in the front with the hard drive cages removed as the front supports 230mm fans but im considering my thick top RAD will reduce that down to most likely 140mm rad being my max choice for front.

 

Would a thick 140mm and 240mm be sufficient for a GPU and CPU loop?

forgot to mention that 5.25" I will remove with my dremel so I can get my RAD in if i have to

It would be enough but you can never have enough rad surface area. I think a similar rad setup as is possible in Prodigy would be good here. This would mean an Alphacool ST30 or XT45 in the top and a 200mm Phobya Xtreme in the front with a 180mm fan on it.

A 240mm and a 120mm is good enough for a CPU and GPU loop. Just get the thickest you can fit.

IIRC, the Phenom shares the same inner chassis as the Prodigy, and if so, the radiator clearance isn't as big as you would imagine. I have clearance issues with my current GPU block. It's an Aquacomputer R9 290, and I can force the rad and fan combo to sit perfectly, but it caused some serious flexing to my motherboard and my graphics card could not sit properly on the screw mounts. My current rad is an EX240 with NF-P12's, so its about 60mm or so of combined thickness. My previous EK 570 waterblock had perfectly enough clearance for the tubing to come out exactly after the fans, whereas now they are a couple millimeters too high. What I ended up doing is not mounting my rad perfectly within the mounting holes, and it is being held on by the edges of screws and only aligned with one hole properly.

Oh thanks for this, yes I'm pretty sure that your right that the inner dimensions are similar, so thank you for your input. I may have to do a few measurement to check this now. Thanks

No problem!

 

If you can fit the fans on the other side of the case, so that it goes fans case rad, rather than case rad fans, then You probably won't run into any clearance issues.
