New Raspberry Pi 4 Firmware Lowers Temperature by 3-5°C
New <i>USB controller</i> firmware, apparently. The fact that it can have any effect on the CPU temperature is a little puzzling.<p><i>I work in a office where the air conditioner is set to 28°C</i><p>Wow. As someone who is used to a room temperature of 20C, 28C is above the point of idle sweating and becoming lethargic. While that's still within the range that most consumer electronics are rated for, I believe a room temperature of 20C is the normal design target.
