I had put together a fan to replace our dead and dying Caframos and had also purchased a “bigger” version of the same fan.
I finally got around to wiring up the Noctua NF-A14 industrialPPC-3000 PWM. It pushes a tremendous amount of air for its size, but it’s quite loud. Not unbearingly loud, but loud enough that our 3 year old granddaughter said, “Turn it off. It’s loud.” One of our dogs also runs into the cockpit whenever it gets turned on. I could build some type of control circuit that would allow me to vary its speed and that would make it quieter, but I haven’t really found a good schematic for a miniature PWM control board that could be neatly attached to the fan.
I also modified some of my GoPro attachments so that I could mount it on the Panavise that came with my GoPro camera. The Panavise is far superior to the suction cup that comes with the Caframo 742 and it provides a wide range of articulation.
I suppose that “when” we cast off the dock lines and make it to some sweltering tropical locale, the PPC-3000 will come in handy. But, right now, it probably won’t get used much . . . unless the frequency of the thing is also magically a mosquito deterrent as well.
UPDATE: I moved this fan to the V-berth before publishing this post and it’s been there for the past 2 weeks working without a care and it’s not really a bother at night while sleeping.
