Looking for recommendations for a quiet fan and control for a pi4 with MacArthur HAT. Preferably one that fits well and uses little power.
Right now I have a tiny enclosure with a small fan that is running constantly and makes too much noise for my taste, and that case won't fit with the MacArthur anyway.
I did some reading about Argon Fan HAT and an improved replacement daemon for it, but it appears this has a Possible pin conflict.
After reading Marietes tutorial about variable fan speed control it sounds like that is the best option, but also a bit more difficult to achieve and possible conflicts with GPIO pins or if you need the audio output.
Is hardware PWM available to use for variable fan speed control, or is it needed for other stuff with MacArthur and OpenPlotter? And would it be worth pursuing when software PWM seems to be most often used, simpler and readily available?
Thanks for any insights.
