I'm looking to find a replacement ADU fan, next to the writing units on a C6500. M43. It's a 60mm 24vDC fan, and it's surprisingly hard to find in NZ, with a four pin cable. I would like to buy a genuine one, either secondhand or new. Are there any good recommendations for parts places (online) that I can buy this from, and other parts as they might crop up? thanks.
