Raspberry Pi Poe Hat Fan Temp
The obvious solution is to make the PoE HAT provide more power but the original HAT was already at the limit of 8023af PoE could provide with a maximum power output of 1295 watts.
Raspberry pi poe hat fan temp. The PoE-Texas Active PoE hat doesnt have fan pass-through pins so its a non-starter as I said in my earlier post and having to modify the LoveRPi PoE Professional hat makes it. Its a 3757 V DC Class 2 device that provides the 5 V25 A DC output used by a Raspberry Pi. PoE Hat Fan Speeds dtparampoe_fan_temp050000 dtparampoe_fan_temp160000 dtparampoe_fan_temp270000 dtparampoe_fan_temp380000 Toss those lines in the bottom of the boot config file reboot the Pi and it should start picking up the new temperature settings.
The Raspberry Pi PoE HAT fan does not spin at all times when powered on - software controls the fan and it will only start spinning when the Raspberry Pi hits a certain temperature. These results are with a Raspberry Pi 4 8GB booted and automatically logged into an idle desktop not under any significant load. 37-57 V DC Class 4 device.
I am noticing that the fan on the PoE HAT is very noisy. Well at least mostly. I want to fix a PWM 5V low noise fan to my Rpi 3 B.

The fan doesnt spin up until the temperature hits 65 degrees Celsius and then spends the rest of the test toggling on and off in order to keep the Raspberry Pi 4 below its target temperature. In terms of testing we powered it up and used it without a USB connection plugged in.
