Cooling Quiet 1U CPU cooler (socket 1151)?

[Ceros_X]

Anyone have any experience with quiet 1U CPU coolers? I know that any 115x cooler should work.

So far, I am tracking:

Engine 27
Dynatron T459
Silverstone Tek
Zalman CPU Fan Cooling CNPS2X
Dynatron K199

Not all of them are quiet, any recommendations or additions? Not looking to cool a TDP over 65W, maybe lower.

@Josh | NFC is adament that the Zalman CNPS2X is the better/quieter cooler overall because it allows the motherboard to be cooled too.
I would start there too.
