Artic 33 plus, Hyper 212 evo or Cryorig H7

I'd go with Arctic Freezer 33 any day of the week over those other two. Only diff between Freezer 33 and Freezer 33 Plus is that the Plus version comes with 2x fans in push-pull configuration. Rest of the specs are same,

In my Skylake build (full specs with pics in my sig), i have the predecessor of Freezer 33 in use, known as Freezer i32. Since both CPU coolers include semi-passive fan, you'll have 0 dB(A) noise output on low CPU loads. For me, the stock semi-passive fan didn't turn at all until my CPU reached 52°C. And when the fan started to spin, it was very quiet due to the fluid-dynamic bearing. Highest what i saw out of my i5-6600K was 55°C during CinebenchR15 while my CPU idles at 26°C.

Performance wise, Arctic Freezer 33 and i32 have the same cooling performance. Only difference between them is that Freezer i32 only has Intel mounting bracket while Freezer 33 comes with Intel and AMD AM4 mounting brackets. (And Plus version comes with 2x fans.)

When comparing Freezer 33 with Hyper 212 Evo, Freezer 33 has:
* shorter height (150mm vs 159mm)
* better fan bearing (fluid-dynamic bearing vs sleeve bearing)
* far longer longevity for a fan (300.000 hours vs 40.000 hours)
* a lot longer warranty (6 years vs 2 years)
* much quieter fan (22 dB(A) vs 36 dB(A))
* 0 dB(A) noise output (on low loads, fan doesn't turn at all vs constantly turning fan)
* support for AM4 sockets off the bat (Hyper 212 Evo needs AM4 upgrade kit which you need to buy separately)
* cheaper than Hyper 212 Evo
