I think the amount of impracticality that would cause would impair the process.
even though you only joined in 2020, im sure you werent born yesterday and know this is always what gets released first on every performance cpu launch ever for the last 2+ decades...
The reason for my thinking is that i live in a place where its not that uncommon to get down -30 degree C in the winter, if i drive a little inland -40 to -50 isn't unheard of, since we live here we know how to dress when its cold. How impractical it is all depends on who and where you are i think, my knowledge on liquid gasses, overclocking and other things to try setting a record is very much lacking, just thought i give overclockers some extra tips that might work.
