Vibration from hot water baseboard

I've been asking about my girlfriend's place with her old inefficient burnham... well, now I'm back at my place with its fancy Buderus Logamax.

I've noticed that the baseboard in the master bedroom has started to buzz when the heat is running. It is sort of a pulsing buzz... I guess I could try to record it next time I hear it.
What should I look at first? I hear no gurgling, so I doubt there's air in the system... Are the fins just mounted to close to the cover?

Its not the crinkling sounds that my girlfriend's old fin tubes with all their bent fins make... more like if someone had a shaver and was leaning it against the radiator for a couple seconds then pulling it away, the doing it again.

Pull the cover and see if the noise stops.

I'd check the circular pump out for noise.

pulling the cover away from the fins stopped the noise. The end cap seems to be paint glued in place...

i'll see how long i can ignore the loose-looking cover.

is this anything to worry about, or just normal sound-from-the-pump carrying through the pipes and amplified by the misaligned fins/cover?
