I wonder if the fan's fed from somewhere else on yours.
Fanuc OTA diagrams can be found at http://denfordata.com/bb/viewtopic.php?f=15&t=2337
However, I just looked at this set - http://denfordata.com/bb/viewtopic.php?f=15&t=2508 and the spindle fan is single phase powered via Fuse 4. However those machines appear to have 3 phase + Neutral input, whereas the older ones were only pure 3 phase. Do you know what power input your machine has?Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

I have the 3 phases and the neutral on mine, removing F4 fuse didn't stop the fan. But removing the F2 fuse did though. Now just got to find the time to remove those internal sliding cover/panels to see whats going on.
Thanks for your help so far.

Searching the model, turns up the original on RS - http://uk.rs-online.com/web/p/axial-fans/2584718/ but it's discontinued, and they list this - http://uk.rs-online.com/web/p/axial-fans/6196860/ as a replacement.
Might be best to double check measurements though.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

I bought the replacement that RS suggested, slight mismatch on the PCD so I opened up the holes on the metal ring that interfaces the fan and spindle motor, wired it up now no annoying loud noise. Thanks for helping me diagnose this problem.
