Sounds good to me. I would in any case use a heatsink which, by itself, is a little over-rated for the task, and apply heatsink grease to any mating surfaces.
Ah, I was taking it literally. Like a dewar or Thermos brand bottle.
By mounting the flat (rear) part of the hs against the chassis, you are insulating the flat part of the hs with the steel and losing that much hs area that could be used for cooling. Can you offset the hs with some spacers to open a gap in there?
You don't want to cool the heatsink, you want to cool hot running devices.
The heatsink dissipating heat into the chassis is more than questionable.
Again, I do believe isolating the heatsink from the chassis is a good idea.

Which is what Goldmund has been doing for a long time.
If the spacer thickness is sized accurately, the stack effect may even help to cool the chassis.
Well, I've had one of the F5 modules running for about ten minutes, it's getting late so I'll continue in the morning, the heatsink didn't get above cold.
I'm sure it will warm up after time but the initial indications are that they should be sufficient.

With both of the F5 modules working the heatsinks are more than adequate, after over two hours neither are more than warm.
