[https://noctua.at Noctua] of Austria makes some boss-ass fans and tower coolers. When I first saw the magnificent [https://noctua.at/en/home-product/nh-d15-chromax-black NH-D15 chromax.black] in 2019, I wept. I have used Noctua tower coolers and fans for all my [[Machines|builds]] since 2011. They have no peer in air cooling, and can hold their own with smaller liquid cooling solutions.

[https://noctua.at Noctua] of Austria makes some boss-ass fans and tower coolers. When I first saw the magnificent [https://noctua.at/en/home-product/nh-d15-chromax-black NH-D15 chromax.black] in 2019, I wept. They have no peer in air cooling (well, they [[Phanteks|*had* no peer]]), and their tower coolers can hold their own with AIO liquid cooling solutions.
 
NA-AVP1 anti-vibration corner pads come in various colors, and can be swapped. Round form factors are wider than their nominal size (150mm vs 140mm) with the mounting holes of a smaller form factor (120mm vs 140mm), and intended for use on tower coolers. NA-SAVP1 is a pack of NA-AVP1s.

I have similar tables for [[EK-Vardar]] and [[Phanteks]]. Disclaimers: data were taken from Noctua's site, and generally refer to maximum levels. Power, noise, pressure, and airflow are not generally linearly related. Performance curves were taken from wherever I could find them; I cannot speak to their accuracy, and they probably do not reflect equal testing conditions.

==140mm fans==
==Comparison of different sizes==
I've selected a representative 120mm, 140mm, and 200mm fan (coincidentally, these are the same three sizes of Noctua fan that can be placed as designed into a MO-RA3 external radiator). Note that the 200mm has less than half of the static pressure of the other two fans, though it moves more total air (at less RPMs, and more quietly).

A MO-RA3 420 can equip (on both the front and back on the Pro, or just the front) 9 120mm fans, 9 140mm fans, or 4 200mm fans. Assuming we fully load it, the differences described earlier are exacerbated. The 4x200mm configuration now falls far behind in total air moved, but also requires only about 25% the power of 9x solutions (its acoustic maximum is also about half as loud as the other two; the 9x140mm configuration is exactly twice as much sound energy). Note that only the 9x140mm arrangement fully partitions the 420x420mm area of the MO-RA3.

The maximum power draw is the 9x120mm setup at 15.12W of 12V power. A SATA power cable provides 3 pins of 12V power at 1.5A each, for a total of 4.5A of 12V power, 54W. A single SATA power cable at spec ought be able to more than sufficiently power even a push+pull 18-fan configuration. The calculation changes if pumps are also involved, of course. Either way, everything here ought be 12V.
So which configuration is best with a MO-RA3? While it depends on the installation's needs, I'll likely go with the 9x140mm. I could make an argument about it running at less than maximum speed and still moving more air, so who knows how loud it would be, but mostly I just don't want unsightly gaps in my radiator coverage lol.
