Hi All,

I am in the need of a part number for the 3 Fans that are on the PTP 810 rack mount unit on the controller card. Have all ready purchased some fans for replacement but they did not work. The only difference is the replacement fans were 5v - 440mw and the original ones were 5v - 500mw. Dont see why they wont work. I ended up using some fans from a spare unit and got it back up and running.
