Noctua NF-12×15 Slim Fan Performance Review
NF-A20PWM
If you’ve read the introduction, you’ll know that the NF-A20PWM is a 200mmx30mm fan. Being a Noctua product no expense has been spared on packaging, with the fan coming in its own presentation box, which as you would expect offers all the detail and key features you could ever wish for.
The instruction booklet (yes the fan comes with an instruction booklet), is tucked neatly into the lid of the box, with the fan itself nestling in a plastic insert
Lifting the insert out reveals the accessories box which along with the usual fan mounting screws contains four rubber low noise mounts, a fan splitter, a speed reducer and an extension cable. As you can see, the instructions are also pretty extensive.
As there’s no real industry standard for mounting holes on 200mm fans, Noctua have tried to cover as many bases as possible. As you can see in the image below, the NF-A20 has holes spaced at 154×154, as well as 110×180. by including 170x170mm holes Noctua have also enabled the fan to be fitted to cases designed for 230mm and 250mm fans.
The A20 is also 30mm thick as opposed to the more usual 25mm, so if you’re thinking of getting one, it’s worth checking compatibility with your case.
