The weather is quite chilly outside, prompting Victor to focus on warmer ideas. Today’s hot topic revolves around heat, particularly the ongoing debate regarding the temperature threshold at which air-circulating fans lose their cooling efficacy. Interestingly, there isn’t a unified scientific opinion on this matter: some research indicates that fans become ineffective when temperatures reach the low to mid-90s, while other studies suggest they can still provide relief even in the triple-digit range. Fortunately, we’re far from experiencing such extremes today.
