Intel-based Mac Firmware Updates

Hei!

My 1.83er is a lot cooler now, only hat it idle since, but temp came down from ~60-65 to 48-52 ° Celsius... That's definitely an improvement for me!

And woooaaa:eek: installing it I thought it would take off sonner or later, the fans sounded like an airplanes engines. Never heard that before, nor even near that when it was runnung at ~90°C....

And yes - doesn't moo anymore but still whistles...

I just updated my intel mac mini (before reading this thread). It was previously running silent (possible hot, who knows), but now the fans come on (not as loud as they do as it's updating, but loud enough to notice when it's quiet.

That's a bit of a downer, especially since I'm using it as a home theater PC. It's by no means loud, but definately not silent anymore.

I guess it's a good thing for it to run cooler, so I'll just have to put up with it...has anyone out there with a mac mini experienced crashes before this update that are now fixed?
 
I have to say, the fans at full speed on my mini shocked me! Amazing how noisy they were.

Afterwards the comptuer sounded the same though.

Call AppleCare (don't go to the store) and they will replace your logic board causing the whine. They fixed mine.

I updated my 15.4" 2.0GHz MBP to this tonight.

pre update idle: 65* C CPU temp. post update: 63*
pre update maxed (both cores, using SystemLoad.app): 88* C post update: 81* C

So I would say it is an improvement.[/QUOTE]

Where can I get this SystemLoad.app?
 
Where is everyone finding their CPU temp? A downloadable utility, or some included app?
 
i updated my intel iMac last night...and WOW were those fans loud. i'd never heard 'em that loud (much less any computer i've owned). don't really notice a difference in fan noise after the update...still 'whisper quiet' :)

Sounds like the "fix" involving editing kernel extensions was just an indication of the real problem. The kernel extension, when edited, just ignored the hardware sensors. The real problem was probably miscommunication from the sensors to the OS. Hence, firmware update.

Just updated, that core due temp app is wack... it was at 27 (lowest I have ever seen it) then afterwards it is up to 75, now sitting at 72.

I still have the whine though, so you have had experience with applecare replacing your logic board cause of teh whine (the one that disappears when you open PhotoBooth)?

Oh totally. However only after the "Genius" at the Apple Store embarassed me. The tech I spoke to told me there was a problem with the MBP and the iSight and they'd fix it. They also said they'd test the heat.

Got it back, no whine, hot as ever. Call AppleCare directly.

Is it really accurate?

I am just wondering if this program is accurate.

I downloaded the current version this afternoon and it states that my MBP is at 10*C (50*F).

I have installed the update from Apple.

I still have the whine. I still seem to have heat issues. I have not done anything heavy, just downloaded a few things and surfed the web, yet, it is still hotter than my PB. It is uncomfortable to leave your hand lay on the mid/upper left side.
 
just got me a 17" macbook pro from my local apple store .. just downloaded the firmware update and also istalled the CoreDueTemp. here are my readings :

47 Degrees C
Current CPU Frequency 1600Mhz
CPU usage 3.2 %

No whine . the only nempreture rise i noticed is when i plugged the power adapter in.. i noticed a tempreture increase the really scarred me. but it cooled down verry quickly .. hope this is a good sign >??
 
Never had any problems with whinning aka moo prior to the firmware update, the thing did run hot though. Ever since the update however my wireless connection sporadically drops out and fails to reconnect...... Any way to reverse a firmware update?

The whining and the "moo" are different things. I had both in my machine and you can distinctly tell the difference.

Installed the update on my 15" MBP this morning and was getting lower temps than before = averaging out at around 62 deg. Getting 68 deg now.

Check your preferences because mine kept on reverting from deg C to deg F and back for some strange reason.
 
i performed the firmware update, so i could install bootcamp.

i have a week 13 build MBP.

since doing the firmware update, opening the mirror widget NO LONGER stops the MBP whine.
 
Any word on when this is comming out for the 17 inch? This processor buzz/whine/humm gives me a headache, and the strip of shell above the keyboard does get wicked hot, not quite burn me hot, but still hot. Wish I had this during the winter ... sit this in my lap and save money on the heating bill. One other questions as long as I'm making a post, is anyone else's disk drive wicked loud? mostly just when its taking a disk in/starting it up or switching chapters. I was running this on a stainless steel table at work, hoping the thermal conductivity of the material would keep it cool, still got very hot just running iTunes and the Sudoku widget for 3 hours, and the table was pretty toasty as well.

I did the firmware update and man that was the first and only time (so far) that I have heard my fans at full. Wow that fan can get laud! LOL

As for the Mini still being quiet, it is. I haven't noticed any differnce in the fan noise before or after the updater.
