H80i vs H90 vs Nepton 140XL vs Kraken X41 - 120/140mm CPU Cooler

[AngryGoldfish]

Although I could squeez a full 240mm radiator in my Fractal R4 case, it will be a tight up top and I'd rather keep the front clear for at least one intake fan to blow across the hard drives and GPU. So I'm looking for a 120/140mm radiator liquid cooling loop to install either in the second 120/140mm fan slot in the front of the case, or at the rear vent as an exhaust. My options so far:

 

Corsair H90 - single push 140mm fan

Corsair H80i - push/pull 120mm fan

NZXT Kraken X41 - single push 140mm fan

Cooler Master Nepton 140XL - push/pull 140mm fan

 

Anything else?

 

Hoping to overclock anywhere from 4Ghz to 4.5 depending on the quality of my 4670K chip. I may need longer piping for some coolers if I am to install the radiator in the front of the case. For instance, I've read that the H80i will not reach. Any thoughts? I'm hoping for quiet, efficient and consistent performance, not insane overclocks. I'm currently using a 212 EVO+, but I would like to replace it with a liquid cooler so I can fit more RAM in—and because it might be a fun project.

 

Cheers!

Either the Kraken x41 or the Nepton. Most likely the Nepton with the push/pull over the Kraken with just a push.

Thanks, man.

 

Also discovered the Enermax Liqtech 120X. Seems to be on part with the others, generally.

 

Based on more and more of the reviews I'm reading the H90 and the Nepton are coming out on top.
