I just did a Software Update and a MacBook firmware update for the fan problem was listed. I downloaded and applied it, was about 768k, said that the firmware is now 1.0

I did this about two minutes ago, I have the system connected to the AC and at BETTER PERFORMANCE and haven't heard the "mooing" yet.

OK, so I'm really hitting this thing hard. The fan doesn't start and then stop, producing the mooing, like before. They start out soft, then get louder and louder the more I do. Most of the time it's quite though. Sure leaves me hopefully that they've fixed the "mooing" issue.

Yeah, that's what I'd like to know. I'll have to check CoreDuoTemp for a few hours and see what happens.

I only ran the system for 30 minutes before I left work. I had a lot of applications open and running and it didn't seem as hot, but that would make sense if the fan is running more then on, off, on, off, that the heat would dissipate more and be somewhat cooler. How cool, I'm not sure.

I'll wait for some more reports, since my Macbook is used in a production environment currently. I'm looking forward, though…

OK, so I've been using my MacBook for about 45 minutes now, and the temperature is 52oC! My pre-SMC update temps were on average at about 66oC.

So all these processor temps are no good if they don't change any thing in terms of real world usage. Well, the top left corner of the MacBook used to be pretty hot after about 45 minutes of use... now its barely warm, AND I have been using it on my bed for the last 30 minutes, meaning it has had a lack of ventilation.

The underside of the MacBook used to be the hottest, the area nearest the ports. It was literally too hot to touch. Well now, its warm, but VERY barable, and I could easily use it on my bare legs if I so desired.

Without getting too excited, things are looking good !

My Macbook was running 145-150 F all day. I installed the firmware update and the temp is sitting steady at 133! That's a huge drop.

I can tell that Apple lowered the fan activation threshold as the fan is now on at low speed and it was not on at this temp before. It is only audible if I put my ear on the keyboard but I can feel the gentle airflow coming out of the case. And reasonably, starting the fan sooner, spooling it up faster, and keeping it on longer are the only ways Apple could drop internal temps without throttling down the CPU.

Nicely done, Apple!!!

I knew they would get this worked out!

I was skeptical but but pre-update I averaged on about 68 with peeks at 80. Now I am getting an average of 60 with 63 the highest.

Small difference but it is noticeable.

I'm seeing drops of about 6-10C normal load, 10C under heavy load, so it was worth the update.

Yeah, it used to sit around 67-72 C doing normal tasks. Now its 58-62 C. The fan is barely audible and you can't hear it over the din of an AC or a fridge. Amazing what just a little air movement can do. I wonder how battery life is impacted now...

OK, I've been using it for a while and the heat of the top left corner and the understand are MUCH better, much. I'm very happy about this, this fixes the one issue I had with this little guy, what a great machine.

Interestingly though, after the SMC firmware update it said I was at version 1.0, wonder what it was before? Maybe since it wasn't at 1.00 they rushed the model out for the summer buying season?

I too am also seeing a dip in temps with regards to my normal usage. With the mouse, iPod, two external HD's, and speakers, it's dropped 10 degrees I'd say on average. Big question though will be the battery life, and if it is affected that much.

CoreDuo Temp, just google it and install, and it should give you what you want.

I've also noticed a ~10 degree drop, but better than that the case is noticeably cooler.

My Steps
1. Applied the firmware update
2. Added 1 gb of corsair ram

Conclusion
Now the laptop is extremely faster since I updated from the stock 512mb. Although my fan spins at a low constant speed. The temp sits betweens 45-50C under normal usage. Amazing I love my macbook even more.

10C cooler seems to the consensus (same with my MacBook 2.0), with no noticable fan noise. Good update.

I never had the moo so I'm wondering if I should apply the update at all.

I guess the fan threshold temp is reduced and people actually get slightly cooler MBs which is nice, but...

What about noise? I don't mind fans running all the time, as long as I don't hear them in a quiet room. Has anybody got the impression the MB now makes more noise after the update? Is the consensus here really that you don't hear the increased fan activity?

Installed the firmware update and my temps are now at 57-60C whereas before it was at 66-68C. The case is much cooler as a result.

Haven't really heard the moo since I installed but I never really heard it much anyways. So that was a nonissue. Now that the temps are lower I don't think I will have that problem.

You will upgrade the firmware sooner or later. Might as well do it now. No point asking whether or not you should IMO.

Caleb, you can just click on the Apple in your menubar and go to software update.

does this help the shutoffs problem at all? maybe it'll be a stopgap solution for me until i can get my macbook in for a new logic board. (i can't do that until i get to Israel, since now there's not enough time for the repair...)

idle hasn't changed (but mine wasn't really running hot) from 58-60. but load is about 8-10 deg lower! yeah! can't hear the fan at all, the processor whine kind of drowns it out LOL. oh, and upper left of the back of the macbook near the power input is MUCH cooler to the touch. NICE.

good update apple, wonder why this fan behaviour wasn't there from the get go, but hey, better late than never.

actually my macbook stopped mooing after the logic board was replaced but when I was doing something processor intensive like convert a dvd to mp4 the fan roared like a lion. I prefer the constant slow fan which is barely noticeable after the firmware update. Not to mention the highest temp I've seen so far is around 57C when using safari, itunes, firefox, quicksilver, ichat, flickruploader, and iphoto.

I'm actually on my second MacBook, my first one purchased from CompUSA on 5/19/2006, never had the "mooing" problem, but it did have the "sizzling" AC adapter. I called Apple and asked for a replacement AC adapter (this was when the first reports of Dell systems catching on fires and exploding were coming out) but they had me send the whole MacBook in. I had it for about 10 days and then lost it for 7, miserable, but the replacement that came didn't have the problem with the AC adapter, however the "mooing" was now an issue and the case seemed just as hot with the second as the first.

No more mooing her either, which is very good news, because it could be annoying. Overall temperature dropped about 8 degrees celsius to around 60-62. Very happy with that
After 18 years of MS-DOS and Windows working very happy on Mac, now on a 15" MacBook Pro 2.2 Ghz - 2Gb memory - 200 Gb HD with a 20 and 23" screen. I've been waiting for the iPhone for quite a while, let's role it out in Europe. Just one wish left for now: a light mac (2-3 pounds) with 8 hours of working time. They can do it... :-)

I personally have to try to hear the fan by putting my ear very close to the keyboard. With both palms on the keyboard I can sort of feel a very slight vibration that wasn't there before. In all honesty, I flipped open my macbook this morning to check my email and I didn't notice anything out of the ordinary.

Did you read the instructions? Cuz you really should for ROM updates.

"After this update has completed successfully, your SMC Version will be: 1.4f10."

The "1.0" means it was just the first update for the MacBook SMC ROM.

I never had mooing either but mine did get hot as hell.

Now it is cooler and doesn't sound the least bit louder.

After nearly an hour of standard usage (Safari, iTunes, Adium, iPhoto, Textmate), my MacBook (post-install) has yet to reach 40ºC! I never had any mooing or heat issues, but that's just freaking incredible. I'm in a pretty noisy room, so I can't hear if the fans are on at all or not.

Two thumbs way up to Apple on this one!

Hmm. I have several browser windows open + a couple word docs...and I have been hovering at 60-62 celcius....I think I may have been at 70-72 pre-firmware update.

Anyone have an external 20.1" plus hooked up with this firmware update?

I am pre-update with a 20.1" and my fans aren't on at all. Temp idles at 66C.


I really don't want a scenario like my 12" PB where a 17" external display caused Turbo Jet action. That was REAL annoying.


UPDATE: Post-Update - Its more 12" PowerBook like, but not as annoying when at idle. I am UnRARing some files, running at 56C and the fans are running at a much higher speed. Before the update the fans didn't come on until like 78C or so.

While typing this post, the UnRAR finished and now at 52C and the fans aren't on at all. Weird. Maybe it has something to do with proc load and current clock speed.

Anyone else?

Microsoft Office, because it's not a Universal binary, would always cause the mooing to start. Parallel Desktop would cause it sometimes too, but not now!

You did download CoreDuo Temp right? It's not giving you a reading?

You need to download and install the whole CoreDuo Temp program, which installs a framework to read the CPU temp, then you can use the widget, but only after the CoreDuo Temp program is installed first.

Actually, I never had any mooing.

I also have a Dell 20" widescreen monitor attached. Will check my temp later when I detach.

Just was not sure if 60-62 is good for this combo of Word / Browser windows etc

This is a much better app to use for temp readings:

iSlayer.com

You can use the advanced or nano version.

OK...So after some time with my 20" Dell monitor unplugged, my core duo read out post firmware upgrade is 60 / 62 degrees C. Is this as good as it gets? Again, I have a couple word docs open / Macnn of course
