Which - why do I have to order different part numbers for back to front airflow? It's just a fan, can't it be made reversible? Seems like that would be cheaper than stocking alternate part numbers.
The fan is inside the power supply right next to the high-voltage capacitors. You shouldn't be near that without proper training.
Meh… Turn off power supply input switch, open chassis carefully, apply high-wattage 1Ω resistor across capacitor terminals for 10 seconds. There isn’t going to be any high voltage left after that. Owen
