Hi @Bernard,

This is what we have tested:

1. [MB40100V2-000U-A99](http://www.digikey.com/product-detail/en/sunon-fans/MB40100V2-000U-A99/259-1565-ND/2757776)
2. [MC30060V1-000U-A99](http://www.digikey.com/product-detail/en/sunon-fans/MC30060V1-000U-A99/259-1545-ND/2757809)

Connect it using 0.05" (1.27mm) 2 pin socket to J14.

Fan On/Off temperatures (with hysteresis):

1. Will be on, when temperature is more than 55 deg C
2. Will be off, when temperature is less than 45 deg C

Connection diagram is as shown bellow.  
Hope this helps.
