I have a T630 PowerEdge and recently purchased and installed a new GPU cooling fan assembly.  I'm questioning if it is working.

There are 2 fan assemblies installed at the rear of the case in the cooling shroud but iDRAC -> Hardware -> Fans only shows 2 System Board fans installed.  I was expecting a total of 6 fans to be shown if the cooling fan assembly were plugged in and working properly.

What am I missing?
