From 93f1e6dd86bf6168f2bae163213143063242391e Mon Sep 17 00:00:00 2001 From: Justin Schuh Date: Sun, 24 Nov 2019 18:37:30 -0500 Subject: FAN: Kick start fan when the increase is more than 50% (#2085) Large increases in fan speed can suffer from acceleration lag, so this change kick starts the fan for a change of 50% or more in the same way that starting the fan from 0% does.
