Default G4 Nitro Fan question

Guys I am thinking about a new build and I need to know if the Fan that comes in the G4 kit fits the YS or OS threads. I have searched and can't seem to find the answer. Tower lists a "discontinued" fan for the YS.

Thanks

The fan will fit both. The cooling fan housing is PN PV1625, fits the OS and YS
