    @ehume Coincidentally, I was reading about static pressure before I posted here.

    The Enermax Revo has a thin plastic insert under the fan, covering about a third of the open area. I am sure this dust cover would add to the static pressure as it impedes airflow into the PSU.
    No. 99% of PSU fans have this "baffle". It's an air diverter to prevent the air closest to the exhaust grill from immediately escaping out of the back of the PSU.

    I'm not sure I even have a power supply that isn't at least 10 years old!

    Interesting, I also have a supply whose fan is controlled by the PC mother board.

    Oh yeah, right.
    You can't replace the fan.

    Because Enermax does some weird fan stuff.

    They use 3 pin wich might be thought of as PWM but its not.
    They use a constant 12V, a (voltage?) regulated pin and the RPM signal..

    Any way to get some oil into the old fan's bearing?
