From 328d485a2bea7c2f62e2509f0e31d8432465e5de Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Wed, 18 Aug 2021 17:26:49 +0100 Subject: [PATCH 545/552] overlays: rpi-poe-plus: Improve the cooling levels The PoE HAT cooling levels are not well suited for the PoE+ HAT - the fan fails to come on until the temperature reaches the third trip point (50C). Give the rpi-poe-plus overlay a different set of cooling levels - 0 32 64 128 255, as suggested by @chris-kai-in.
