Will a 280mm AIO fit in the top of a Fractal Design ARC Midi R2?

More specifically the Cooler Master Nepton 280L. The manual says 240 or 120, but three 140mm fans fit in the top, and the mounts are offset quite a bit so as to not interfere will mobo/ram. I don't see why a 280 or larger wouldn't fit, but I wanted to double check. If anybody knows for sure I'd appreciate it.

  1. From a Nepton 280l review http://www.hardwarecanucks.com/forum/hardware-canucks-r....
    "Unfortunately, the Nepton only uses the newer 15mm spacing for its 140mm fans while the 120mm fan spacing is completely unique"

    Maybe you can measure the spacing between the 140mm fans on the top of your case (15mm).
    The Nepton 280l's radiator is also 30mm thick and a fan is usually 25mm. That's ~55mm clearance that you need from the top of the case to any component.

    That link is broken for me, says page not found. I'm not sure what the 15mm spacing means. Does that mean between the fans?As for clearance I'm not worried about that. As I said the mounts are offset so the radiator will be in front of the motherboard, not intercepting it.

    I feel like an idiot, but I still don't get the significance of the 15mm. The fans look like they are side by side on the radiator, where exactly is the 15mm.
  4. 15mm from one set of fan to the next.

    From this review http://www.hitechlegion.com/reviews/cases/34307-fd-amr2 "...the Fractal Design Arc Midi R2 is accommodating to liquid-cooling enthusiasts and has been designed to support a pair of 240mm or 280mm (15mm spacing) at the same time on the front and top."

    5.25" drive bay might interfere with radiator though.

    Ah! Thanks so much for taking time to clarify. I'm sorry for my ignorance, I've been out of the case/cooling loop for a while. I think I've actually decided to go with the h100i for ensured compatibility and just because of how good and popular it is. Also 5 vs 2 year warranty on Corsair vs CM respectively. Now I'm trying to find fans to use in place of the stocks since gentle typhoons are impossible to find now. Any suggestions?
