From what I gather the bottom of the EZL uses the top of the fender as a heat sink. Seems it would work better with an aluminum heatsink and fan as used with CPU's unless the engine compartment is too hot. Ideally it should have more exposure to ambient outside air to keep it cool. If they fail because of inadequate cooling I question whether the original cooling design is at fault or fails when the conductive paste fails to cool it after age and must be replaced on a schedule.

The other concern is insulation from metal to metal indicated by a plastic film. I haven't removed mine yet, is the fender is painted or bare metal under the EZL?
