Passively cooling an i7-6700 (non-K)?

[Synomenon]

So I'm setting up a new system in a Corsair 380T ITX case:

CPU is an i7-6700 (non K).

Motherboard is an ASRock Fatal1ty Z170 Gaming-ITX/ac:

The Corsair 380T has a max heatsink height of around 150mm. Tried the Cryorig H7, but its massive backplate got in the way of the M.2 drive. I'd rather not use liquid cooling since I'd be adding pump noise to the system.

So now my next choice for heatsink is the Noctua NH-U9B (any of its variants would fit in the case).

I have a 200mm fan on the front of the 380T and a 120mm fan on the exhaust / rear of the case.

The NH-U9B would be sitting directly between the two fans. Since the i7-6700 is only 65W, would this setup be sufficient in cooling the CPU or should I still add a 92mm fan or two (push/pull) to the NH-U9B?

yeaaa no.. you aren't going to passively cool an i7. Try this;

It's height with fan is only 58mm, it is what I use.

I'll just add 92mm fans then to the NH-U9B. I was just scared to try running it without a 92mm fan or two clipped to it (even though it's sandwiched between the 200mm fan and 120mm fan).

Bath of mineral oil maybe? You'd still need a pump to circulate the oil through a radiator or chiller or something though.

How about the stock cooler? In non-AVX loads, it should be plenty quiet.

If you do get an aftermarket heatsink, I would opt for something that comes with a high quality fan, e.g. Noctua. Most coolers' fans are not nearly as quiet (at low RPM) as the fan on Intel's stock cooler and will not be as quiet at idle.
