A Noctua Fan Overview – 40mm to 200mm Varieties!

Posted December 31, 2017 by Brendan van Varik in Cooling

Overview

Hardware: Cooling

Manufacturer: Noctua

WHAT WE LIKED:

Strong airflow at extremely quiet noise levels, but we all pretty much knew that already, Great Quality

WHAT WE DISLIKED:

Color Scheme may not appeal to all

BOTTOM LINE:

If you can afford the premium price that comes attached with Noctua products, and you don't mind their browny-beige color scheme, then they are absolutely one of the best fan makers in the world.

The 40 mm Showoff

Within this category, we have four fans from Noctua that are supposedly ranging from 5v to 12v, and most of them spin at 5000 RPM. Whether or not they will be loud is a huge question begging to be answered, but we will get to that real soon… I promise! For now, let’s take a look at what we have within the boxes of their respective fans, and brush over a few key specs for each. I’m not going to mention that there’s a fan in every box … because if that wasn’t obvious, well, you probably wouldn’t be reading this! Anyway, forward, march!
