PiKVM v3 Fan Replacement Notes

The fan on my PiKVM v3 started getting noisy so decided to buy a 4 pack of 5v 30x30x5 mm fans to replace it. You need to remove the screws from the top, then unplug the fans. The black wire is toward the "front" of the case where the display would be. Also the fan label faces outward as an exhaust configuration. Make sure to hold down the nuts to unscrew the fan. Tighten it well after replacement too. Found that the screws were loose on the original fan, not sure if it just vibrated out that way.
