im will to bet a h100i will still beat it because its a 120x2 raidator.
again... u cant mount something like on your cpu.
the cooling setup itself requires a special case which are labeled "watercooling friendly" to be able to mount a 120x2.
at best air coolers will trump a H60i.
i wont deny that claim, however once u start getting into larger radiators, it like the tortoise vs hare, only the hare stopping means ur pump has broken.
See . . . I think Corsair, CoolerMaster and the others are making these H100-type kits with just the cooling capacity to best the air/heatsink options. I said elsewhere: if you spend $120 on the Nepton 280L, you don't get a $95 water-pump.
But here's the Frosty-Tech rundown with their test-bed, ranking the Nepton against the other options and entries. Generally, I'd take these reviews as reasonably reliable bolstered by cross-reference to similar reviews of other origin which need only include a few of the coolers in other reviews. You know -- "if A > B and B > C then A > C."
But look carefully at this. The Nepton "Low" or "Quiet" ties -- EDIT: Whoops! 3C better -- with Noctua's recent NH-U14S:

Other reviews featuring the U14S included the ol' D14 in the mix, showing the U14S besting the D14 by 5C. But I replaced my D14 "limpo" fans with a single Akasa and closed that margin exactly -- 5C improvement. Figure that you MIGHT be able to see improvement just chucking the fan bundled with the U14S.
On the "high" fan setting for the Nepton, more than 6C better than the U14S, but we could wish to close that gap all or partly with a fan replacement.
So -- what happens with a "twin-U14S" to be released in April -- a sort of "X14" successor to the D14? We don't know. And I have no doubt that CoolerMaster will go back to the drawing board, get their cost-accountant to join the team, and see how they can improve.
According to "physics," improving should be easy. But the cost-accountant -- the devil is in the details. And no $95 water-pump likely!!
