As promised, the video on the Onyx's keyboard and also the Fan Boost (aka the fan at full speed). Please excuse the static in the background and the slightly dark video (I need to get myself better equipment, plus this is my first time churning out a video), but otherwise I'd say the sound is pretty representative of what you'd hear in use (expecially if you're using headphones to view the video).

So yeah, normal typing force initially and then harder typing. There's that Windows beep there too (somewhere on the middle) to give you a reference point of sound levels  (unintended but pretty helpful lol).

ALSO, the I had the laptop on a really wobbly plastic container (only "base"I had around that was free) so don't mind the laptop wobbling around while I was punching the keys hard.

And, just to reiterate, that fan doesn't sound like that ALL the time.

Oh, and I managed to film Onyx disassembly for upgrades/maintenance as well. As I can junk the sound on that one you can look forward to a less static-y video when I'm done with it.

Or you know, an Apple Wireless KB...

As for the Procs, it's probably that... or, it might simply be that it's fractionally cheaper, which adds up when you buy container-loads of Procs for mass production. The fact it runs cooler also means you get to save a bit on cooling design as well, and hence the savings snowball - leading to increased profits.

It's not that your average consumer is going to miss much from having the 8750H over the 8850H.

Plus, the Onyx (GK5CN) and the Zeph GM501/GX501 notwithstanding, the other thin/lights already out aren't exactly coping all that well heatwise with "just" the 8750H either lol (or at least that's what their respective Owners Threads over at Notebookreview Forums are leading me to believe anyway).
