I'm planning to install a set of moon disc hubcaps. I've read that these could cause overheating problems (no vents in the cap to allow cooling).

I have an '05 Civic coupe (front disc/rear drum), and using a Fluke mini 62 IR thermometer got the following readings:

85F all four corners (ambient temp after sitting in garage overnight)

after my 37mile commute (30mi highway, 7mi stop-n-go city):

(LF)120F (RF)119F

(LR)112F (RR)112F

I'll monitor the temps over the next few days to establish a baseline, and again when I install the moon discs. But my question is how hot is too hot, at what point should I expect to encounter brake fade and/or rotor damage (warping)?

Too hot is what ever exceeds the maximum temp rating of the pads, or heat soaking the brakes enough to boil the fluid.

isnt it too hot when the break pads begin to burn? lol.
