FYI: These supplies generate quite a bit of heat when driven near its max for a while. Despite the high efficiency of these supplies (~85%), outputting ~550w generates close to 100w. So, that fan is needed when they are driven hard.

If you are enclosing them in some kind of charger station case, you could probably use a larger fan (which doesn't need to spin as fast for the same CFM) as long as the air is directed through the power supply. Then you could do that fan speed reduction mod. IIRC, you can't simply remove the fan because the supply needs to see some rpm or it won't function.
