Hello Dear All,
Yes ideally we could have a robust solution to cool down and stabilise the sensor temperature to a bit lower temperature than the fan only can achieve, for now the fan blower only is designed to do all the cooling, but that is of course not top optimal.
Best of world would be a cooling device to lower the sensor temperature, namely a Peltier.
Astrophoto cameras use this cooling system, with a sensor in an Argon dry gas filled low pressurised chamber.
with this kind of device, you can cool down the sensor to -50°C below the ambiant air or even lower, to achieve very low sensor noises.
Unfortunately, our Chronos sensor here has not the same very low base level of noise that an astro camera require.
Probably Chronos Sensor in his specs is not designed to best work in too cold temperatures.
Adding a Peltier MOD that will be safe, will be a hard job, if not even impossible, without a big mod of the camera case. Furthermore, you we have to
be EXTRA-Careful of one big Drawback of sensor Cooling :
And
this is CONDENSATION ! if the ambient air is too wet, (hygrometry high) the much lower sensor temp, with not enough wind to prevent the air damp condensation will surely let water droplets and humidity inside the electronics and will have the issues you can imagine.
A Peltier is a power hungry device too, so you will need to provide extra power.
That would be a really interesting experiment, but, you know, the Chronos is an expensive jewel and unless you have really good engineering and craft skills / 3D tools, this adventure might be too much and risky to try.
Same thing, if you have your Chronos cooled down with a portable air conditionner exhaust,
the WARNING is : Be careful in really Wet and hot Ambiant air conditions, that might build-up some condensation into the sensor or electronics.
Just my 2 cent worth
