The camera's metallic case is a good conductor, so I decided to experiment to see how much cooling I could get by surface mounting a peltier cooler. I bought a very inexpensive (less than $5) 93-watt peltier and a $15 PC heatsink and fan.
|The Alpine 64 has low vibration and 90 watts of cooling capacity|

|The working device!|
|Initial image. The original chip temp was 22 C. In a few seconds, it had cooled to this value.|
|Significant noise reduction at 0.5C|
