“Ok does the job, but I would prefer a larger more effective cooler. Why o why can you not easily adjust the fan to cut in at lower temperature. A simple utility would allow people to bring the fan in at a moderate rpm at a lower temperatures to get progressive cooling. More heat and the fan spins up or slows down at lower temps. Raspberry should developed a cooler for over lockers. Large heat pipe coolers are available and work well but why no official one?”
