I finally got time to replace the noisy power supply fan in my DesignJet 130 and thought I’d pass along my experiences for others with the same problem.
The fan is 24V 60mm box fan. These are much harder to find than the more common 12V box fans. Here’s where I found my replacement:

It is an exact fit for the OEM fan.
To access the fan you’ll need to disassemble the printer to the point where the right end portion is exposed. Fortunately, someone has posted disassembly instructions for the printer. I could not have done the job without them. They are here:

While you do not have to disconnect and remove the power supply and electronics boxes to replace the fan, you do have to remove their attachment screws to get to the fan. The manual shows the attachment screws (four if I recall correctly). Remove them and then push the power
supply and electronics boxes to the rear to disengage them from the metal tabs holding them to the base of the printer. I had enough slack in the wires to do this; of course, your mileage may vary. Once the power supply box is loose, tilt it to the right so you can access one #2 Phillips screw each on the front and back side of the power supply box, near the top. Be careful, the screws are very short and come free quickly. Then pry the top (with mounted fan) off with a flat bladed screwdriver and disconnect the fan from the circuit board.
Since I didn’t have the right connector at hand, I cut the OEM fan wires and spliced them to the new fan and covered the splice with heat shrink tubing. The OEM fan has red and black wires while the replacement has red and blue. I hooked red to red and black to blue, which seems to be
the correct connection.
Next reassemble the printer and hope for the best. The new fan seems about as loud as the OEM fan, but much quieter than the OEM fan with ruined bearings. The whole project took me about 2 hours; I’m reasonably handy, but am not an engineer or technician.
I hope this helps anyone else who has experienced this irritating problem with an otherwise excellent and reliable printer.
