How hot do the electrical components get

[Capt_Zoom]

Do you guys vent your electrical boxes. I'm wondering how hot my electrical box will get if I don't vent it. I'm not planning on putting the coil or reg/rectifier in there but it'll house most of the other stuff. Was thinking of using a leather elec box.

About the only parts that get hot are the reg/rec and the coil. Most everything else runs cool.
