Yes, thank you to all. I'll go ahead with the heat sink on the bottom and consider a fan nearby.

I think we've all learned from this. Good info about the Efratom unit, and sounds as though we should aim for around 38C with the FEI units as well. The FE-5680 looks to be easier to deal with than the FE-5650, so I'll look into that first.
