Update Temperature…
I’ve run my converted V5 main setup, in a cardboard box, for a while now and with just the Dexed snapshot loaded it was reaching 53C and no cooler running 
I’m experimenting with the config.txt temperature settings taken from an answer in this link
To edit the config.txt file I’m using the webui
Hardware > Options > Advanced View > Custom Config
First test takes me to 33C
dtparam=fan_temp0=40000
dtparam=fan_temp0_hyst=10000
dtparam=fan_temp0_speed=125
@jofemodo I know we don’t like fans
