Hello thanks for choosing Dell. I don’t think I can let you know of non-Dell parties’ but this is the information I know. But we also have to know of your service tag (For chassis) as well, to be precise.      Part #:JYT3J Part Desc.:ASSY,FAN,80MM,SUN,MX7000,GEN2  / ASSY Fan, Rear, 80MM, Skylynx, Sunon, GEN 2
Happy Friday all, I see that the chassis has 4 fans in front and 5 fans in rear.  The chassis doesn't come with these fans, so I have to purchase them from a 3rd party.  Do the fans plug into a tray or bank?  Would I need to buy the trey as well? Thank you!
