raymo, I've not noticed it with my 1100D. I do usually use the DC coupler for convenience more than anything else, as it runs off my regular 12v supply to my other astro gear (with a step-down to 7.4v) and I don't then have to bother to change the batteries! Live view does heat things up, so I don't use that except for focusing.

IMO the 1100D is more tolerant with temperature than many of the other Canons...I find once the ambient temperature is down to around 10-12C the thermal noise in 5 minute subs (at ISO1600) is negligible, shy of any prominent hot pixels...both of which would be eliminated through stacking a decent collection of subs.
