Yup-especially at hi ISO's, heat will add noise to an image. The chips used for astronomy are cooled by refrig units. That being said, I just returned from one week with 3 photog's shooting at our Arizona Proving Grounds (aprox 1200 images a day) with temps at about 120 degrees with no visible degradition. The problem only shows up at 800-1600 ISO with long exposure times (over 1 sec). We use D1X's.
