your answer is yes. I remember a rep from hashfast saying that there would be overclocking temperature logic built into the chips themselves. They will adjust the hashrate and intensity if a lower temperature is detected. Best believe it makes a lot of sense to mine these in something akin to an icebox or freezer just to get a huge overclock.
Not a good idea.
a) compressors on fridges are small. They are designed to keep cold stuff cold not remove a 1.2KW heat load.
b) cooling below dew point = condensation onto components which probably don't enjoy getting wet.
I'm just quoting a quote that I heard which is - condensation collects on objects colder than the ambient temperature surrounding them - Asics will always be warm/hotter than ambient air. But I completely understand your second point on A that they are meant to maintain a constant temperature, NOT remove heat. Now you have me thinking about how I could do it but have something cost effective. A data center is obviously available for me but this is pretending that I don't have that and need to run my own home electronics freezer.
