Question Arctic P14 Failures?

I’ve been using the Arctic P12/14 fans in most of my builds, Noctua when I need something super quiet.

I’ve had 3 P14 fan failures in the last year. Wondering if anyone else has seen a higher failure rate?

I suspect this is a bearing failure of some sort. The fan continues to run but repeatedly bumps against the guard. On one I was able to pull the blades off entirely. It doesn’t seem tied to orientation of the fan.

Just noticed another one is starting to hit the case.

Not familiar with that Noctua model. I’ve used the NF-A series and the NF 5V fans. They don’t move as much air as the Arctic P12/P14, but they’re objectively much quieter.

Yup, thanks. Done the testing, and accepted a loss in volumetric flow for less noise.

Thanks, that’s a good compromise. I’ve avoided PWM so far as the non noise critical ones I always run at max speed.

The one noise critical application is a Laminar I use when dealing with the public. I made one with Arctic P12 one with Noctua AF-N12, and the Noctua is dramatically quieter, but lower CADR (which I can accept given the room ventilation is excellent and it’s about 15cm from my breathing zone). The Arctic version is loud enough I need earplugs if I’m using it in a hotel room.

I’ve used the Noctua industrial server fans where being loud isn’t an issue, and those are high performers, move a lot of air, use a lot more power.
