@alan I've got cooling fans on my Pi's. They came with the POE hat. I keep wondering whether to take them off because I'm not 100% sure that they make much difference.
@jamie My fans definitely make a difference- I’ve checked the temperature both with them running and without. They lower the temperature by around 10°.
@alan Probably best keep them on then. The ambient temperature where they are sat can reach 35 degrees on a hot day.
@jamie They're amazing for light work, especially at the price. The only thing that makes me nervous is the reliability of SD cards...
@alan Yeah. It was a bit hacky when I did it, but I think the capability is in the default firmware now.
The POE hat provides enough power to the SSD as well, so each of them only has one cable connected, plus the drive. Very neat.
@jamie Thanks for that. I had a script running to backup the SD card to an identical SD card connected to USB. I then set it to boot from USB in the event that the main SSD was unavailable. I have a spare SSD drive which I could use...
