Running this on my mbPro with Catalina in the blisteringly hot weather. It gives a great indication of all the temperature sensors (29 separate readings! — CPUs, GPU, battery, enclosure, logic board, SSD, and memory). And yes, override control of the cooling fans. Fab little app. I think I got it on a half-price discount. Highly recommended, if only to assure yourself that your Mac is not actually burning itself up in the heat, but cooling quite nicely, thank you!
