Being a captive of the ASI ethos, I have not encountered the latter concept but assume there must be a straight linear relationship but of course that does not factor in possible variables such as humidity, wind speed and no doubt others I haven't grasped. Always ready to admit ignorance and happy to be educated.

Some more feedback……,
After my 2600 is connected and I commence cooling , I glance at the dashboard in APT and notice the power consumption increasing a lot faster than cooling capacity. The start temperature doesn’t drop immediately, it starts dropping once the power consumption is up to say 30% and the cooling capacity is around 10%. This can take up to a minute or so. So power consumption and cooling capacity are not linear or proportional to one another. In Winter , obviously the temperature starts dropping significantly quicker than in Summer.
The power consumption always hits 100% all year round, whereas cooling capacity only reaches say 25% to 35% in Winter to maintain cooling at -10C and in Summer reaches as high as 85% to maintain cooling at -10C.
My 4 year old 2600MC is definitely less efficient in cooling than my 18month old 2600MM.
If fact the 2600MC struggles to maintain a temperature of -10C during hot summer nights and that’s with power consumption at 100% and cooling capacity close to 90%.
The cooling capacity has never gone beyond 90% , it gets to 89% and the camera temp starts dropping to 9.9C or 9.8C , sometimes as low as even 9.0C.
Looks like cooling performance deteriorates with age ?

I’m not quite sure why these ASIair thingys don’t provide more specific data on the cooling of your camera. I don’t use these little red boxes. My imaging aquisition set up uses 5 independent pieces of software.
