ReadyNAS NV: Replacement fan?

Hey folks,

I've got an old Infrant-branded ReadyNas NV with a fan that sounds like it's on its last legs. Seeing the NV Dead thread...

...I'd like to be on top of this situation and make sure the unit is staying nice and cool. I contacted NetGear's support and they pointed me to this thread...

...about replacing a fan in an NV+. Does anyone here know if the fan mentioned there () is also compatible with the original NV?

Also, how exactly do you get to the fan? I disassembled the outer casing, but there seem to be additional metal walls in the way. Do you need to take all the drives out and access it from the front? I'd love a diagram or something.

Thanks, folks!
