They move just as much air in as out. What's different is the pressure capability on each side of the fan I think.

A fan is always pulling and pushing air. You cant do one and not the other. Flipping it around does not change its efficiency in free space.

I don't have that problem. Nor do I ever need to do heat soaking. I just did the heat soaking for verification testing.

I have done it from completely cold to enclosed with a long heat soak.

Carbon and steel expand at different thermal coefficients. Hence your gantry will bend.

Yep but that doesn't solve the bi-material bending issue we are discussing.

I also tried some 0.6 mm U section 20 x 15 but it was not torsionally stiff enough.

I faced the top surface of mine using a sheet of glass, valve grinding paste, elbow grease and a lot of beer. Took longer and more beer than expected.
