Which fan output do you have the hot end fan connected to, and how have you configured it in config.g? Are you sure that the cabling is sound?

The fans are connected to EO and E1 on the Duet Ethernet board.
I don't have my DuetWifi at hand, so I can't check....but it sounds like you powered the fans through the Extruder ports? Or are there fan ports called E0, E1?
Forgive me if I'm wrong, just shooting from the hip.

I agree, that's what it sounds like. The hot end fan should be connected either to one of the always on fan connectors, or to the Fan1 connector and Fan1 left in thermostatic mode - or you could connect it to the Fan 2 output if you are using Fan 1 for something else and configure Fan 2 in thermostatic mode.
