What the model number for Fan 1(showing errors) & Fan 3 (0 Rpm after 15 minutes).

Thank you so much

Mode number of fan is ad07012db257300 as mentioned above. Looks like eBay is best place to get these but they are all from china. The specs for the fan are hard to find elsewhere. It must be the right size, 70x70x25 12v 4200rpm 3 pin
