Noctua NF-P12 Cooling Fan

Fan & Features

The Fan In Detail

When looking at the fan itself, I think you will agree that it looks a lot sturdier than the NF-S12. Utilising an extra two blades  and being housed in a slightly thicker shroud, we should certainly see an improvement in increased static pressure. The fan when picked up has the same feel to it as would be expected from an industrial fan such as a Papst or Delta. As a result the fan is fairly weighty and the plastic definitely feels a lot more robust than most case fans.

Fan Front

One of the most noticeable features on the  NF-P12 is the vortex controlling notches cut into the trailing edge of the fan blades. These are designed to disrupt and spread the drag created by the blades movement, reducing resistance noise. The back of the packaging seen earlier tells us more about this process and goes on to explain that the notches are staggered distances from the edges of the blades to create a range of pitches, effectively making the sound a lot less distinct and far more tolerable.

The cable running from the fan is of a considerable length (approx. 40 CM) and is sleeved with a rubber sheath heat shrink sealed at both ends.

The SSO Bearing

One of the features seen on the NF-P12 is a Self Stabilising Oil bearing. This system allows for near frictionless operation, reducing heat, power input, noise and instability. Furthermore, we are provided (again on the fold out part of the box) with information detailing the massive increase in bearing longevity this technology provides.

Obviously I cannot comment on the bearing comparison but I can certainly vouch for the increase in stability of the blade rotation.

As a follow up to Llwyd's great review on the Noctua NF-P12 we have some hard figures now for the static pressure made available by these fans.

No, thank you mate. I've only added the info that we couldn't get done for your review. But I'm glad you liked it I'll put a link in your review now as I'm about to head off to bed.
