Initially with it off, NB load temps 54-55C, idle 47-48C.
Put it on, NB load temps 54C.
Reinstalled it, put fan against it, NB load 53C
held it on with paste and removed it while running pc, no diff.
Removed it and removed empty WB, (so looks more like UD5) put a spot fan over bare space, load temps dropped to 47C even after several hours of prime. idle dropped to 43.

Not that anyone cares about NB temps on these, but that monster takes up space, a pcie slot, and is useless, especially compared to just a spot fan directly on the NB.
Basically you are saying the Extreme is a complete waste of money unless you plan on WCing the not hot NB?...
