I have a rMBP and don't have the firmware update for Power Nap. Have you guys gotten it yet or has it yet to be released?
Got a tip for us?

Not currently released for the Retina Macbook Pro. 2011 Macbook Airs have a release for it though. Ours I'm sure won't be long!

There's probably no software to tell the fan system how fast to run (based on CPU/gpu/ram temps) while firmware is updating so the fan system ramps to max just to be safe.
Once the smc or system is rebooted, the software is active and can tell the fan system what to do.

No joke! Before the update I thought I'd heard the fans at 100%. I was definitely wrong.
Hmm, I don't remember my fans going to 100% while I was updating... maybe I was watching TV or something at the time.
if im not mistaken and this is just my guess, haven't read up so much:
the SMC controls the fan... but the SMC needs firmware to be able to operate, hence when you update firmware you shut off the controlling part, thus making the fans go with "better safe than sorry" and ramping up to cool down the computer until the update is done.
and on another note: had my TB -> Ethernet adapter plugged in
(with the ethernet cat5e cable) during powernap, within 12h it had consumed 17% battery) ... so theres a reason apple said to unplug things when on battery and powernap is on 🙄
