Yes I would leave at least 20 to 30 sec (I think I used to leave 45 sec) for sensor cooldown since the sensor continues to heat up during the dark frame cycle.
Now I do manual darks not ICNR (In Camera Noise Reduction) and I still leave time for the sensor to cool down.
(Another thing I do is turn off the preview screen or at least have only quick previews because that too produces heat).
Also I prefer to use an external 240v powerpack for the DSLR not the internal battery since again the internal battery creates heat during use.
