You need quite the opposite, more cooling on those overhangs. As you are in the chamber, the heated air wont cause warping like outside an enclosure, so crank those speeds on overhangs. I generally run 80-100% on bridges anf steep overhangs. I do also slow down print speed on overhangs significantly to allow more cooling aswell
Bigtreetech’s btt pi is quite good for printer use - and general use tbh, but it is geared towards printers
