Its a CoolerMaster 600 watt RS-600-PCAR-E3 power supply.
The fan is covered on about 1/3 of the underside facing the heat sink. It seems to be a way of channeling the air to just the heat sink but its not angled so you'd think it would just restrict airflow or reflect some of it right back out. It seems very odd. Wondering if people have noticed this on other power supplies; as its clear its not readily noticable unless you use a focused light to illuminate it or remove the power supply cover.
