Will very long shutter speeds damage my a7?

Possibly a very dumb question, but I am in the process of messing about with Bulb exposures to try and get some star-trail photos. I have read that sensors 'overheat' adding noise to images, but will I damage my sensor if I set a 5-minute (or 30 minute) exposure (for example)?
