Hi there - pretty new to openwrt. Love what you all have done. I built a router from a banana-pi rpi-r3 using their stock (unventilated case). I keep my wifi seperate from routing so wifi was disabled. I started doing some temperature monitoring and saw it was about 58 degrees. Thought this seemed high with the radios disabled and only video streaming going on. I decided to unload the drivers and see if it changed the heat. It did!
Temperatures dropped about 10 degrees C. And held. Maybe this is common knowlege but wanted to give back a little to this great community which has been invaluable setting of my network. Only enabled luci statistics right before the module unload so youl'll have to take my word for the stability before. Modules unloaded
