(View all)Wow. You have any idea how long it'll take to firmware flash/update 1100 G5s?
According to our independent analysis, the fan now spins at a higher rpm, but uses less electricity and kicks on less frequently. It also runs more quietly and with lower torque. Furthermore, from time to time it now automatically spins backwards for 30 secs at a time, thereby reducing the accumulation of dust on the fan blades, and preventing dead air hot zones within the cpu tower.
Does that concur with the rest of you? I dont have my G5 yet, but found it quite interesting that the fan actually backspins... :cool:Originally posted by ddbean
OK, I'm waiting to hear how this goes on a Dual 2 Ghz with 9800 card before I try it.
I have Dual with 9800 card and everything seems ok, so far.

Um, bad news for the Big Mac cluster.

I thought they could 'netboot' (or whatever the equivalent is) the entire cluster all at once?
Or cascade it from one comp to all?
Well, I suppose this would be easier under OS X.....and they're running some Linux flavor, right?

The only problem I have with all this is why is this post about "a" fan, shouldn't it be "the fanS"? I mean there are 9 of them in a dual config. Was this a real test inside the case, or a stand-alone on a test bench?
