Certain types of image sensor noise is quite directly affected by temperature. An increase of 5–10 K usually doubles the dark current, for example.

The same happens in most sensors on the extremes of sensitivity, and cooling is actually a way to correct for some of that. For space based sensor pods cooling is usually the limiting factor for long term deployment.
