Having looked up the camera, being uncooled I would imagine it will show up more by way of hot pixels than a cooled cam. I don't think either way is bad but there is a difference between 0 degrees and -15 sensor temp with my 294. But I am not familiar with any other cameras to say how many hot pixels is normal for it. I just know that a dark frame from my old 350D looked like a very colorful star field.
