My girlfriends MacBook, runs at 15 degrees C pretty much all the time.

Here is a screen shot,

FWIW, 15C = 59F. I've never heard of a processor running that low. Maybe it does, but that sounds really really odd.
 
Hi Guys, i was looking at your cpu temps for your mac books, I have a 12" 1.5ghz Powerbook G4 with 1.25GB RAM, and i get higher CPU temps than you lot, is my G4 faulty... it lasted me nearly 2 years, got passed the faulty battery lark, this is using a new battery apple sent me...

all my readings are in *C...
i am on max performance, and running photoshop, handbrake, and watching an mp4 using mplayer:D

Still saving up for my C2D MBP :D should get it in a month :p

I'm doing mail and browsing the web and I'm down to 22C right now. Room is a bit cool at work though. Last night it was up to about 54C from a normal of about 34C.

Although I never had a RSS, I did apply the update.
I'm curious about those temps you are mentioning though.

I have CoreDuoTemp installed and it shows 57C without doing anything fancy! Just Mail.app and Safari are open and I haven't done any serious work in the meantime.

34C seems kinda low :/
 
Don't believe the impossible!

Don't believe things that are obviously false just because a computers says it. A computer's processor does not run at 59 degrees F after any amount of use, except maybe if you're outside in Siberia. Even if the temperature in the room is just 59 degrees, the processor is going to generate some heat. If the normal amount of heat is very roughly about 50-60 degrees F above room temperature, then, obviously, the temperature monitor you're using is recording incorrect data. One of the worst things about computers is that they seem to be so sure of themselves!

Speaking of such things, I had a especially dull person insist that the outside temperature was about 90 degrees when it was actually about 70 because he saw it on his computer screen (we're in Minneapolis, MN, and I assume he had set his weather page to Minneapolis, Kansas). I almost got into an argument with him, but decided to let it go.
 
I had a pretty annoying RSS on my week 30 white 1.83 MacBook. Typically it would go for 7-8 hours before shutting down, at which point I'd leave it to cool for half an hour or so before restarting the cycle. I am a student and simply cannot do without my laptop for a week to get the heatsink replaced, so I was simply living with it.

Keenly applied the firmware update today and it was running OK, until this. First one on the MacBook. Really hope this is a one-off.

OK, this is getting a bit..... I take back what I said earlier in the thread about CoreDuoTemp matching FanControl's temp readings.

FanControl says 55C, CoreDuoTemp says 37C. Firmware is 1.1.

Does anyone really know what the two are _actually_ measuring? I mean, the differential makes sense if, for example, CoreDuoTemp is measuring the chips temperature, while FanControl is measuring the heatsink.... but does anyone have hard facts what's actually being measured??? :(

Is there a technical document that shows which sensors are installed in the MB? I can't find any, but maybe someone else has a clue.
 
There's another temperature monitoring utility, called appropriately enough, Temperature Monitor. I switched to it after CoreDuoTemp was flaking out on me. So far, it's given me pretty reliable readings. Maybe you guys should try that.

I'm pretty sure readings of 15C-19C are incorrect. I've NEVER seen or heard of modern laptop/desktop CPUs running that cool.

The lowest readings I've gotten on my laptop, from memory, would be low to mid 40s. It usually idles at mid-50s.


With regards to "pushing the machine = shutdown"... that's only somewhat true. Making both cores 100% cpu usage has been a way to trigger the random shutdown, but that doesn't make it the cause. I've had plenty of situations where my MacBook was idling and just turned itself off...

well thats wrong pure and simple. any type of circuit WILL generate heat unless it is a thermoelectric cooler which this isn't

also about the update, i just got a box like 3 days ago to return it to apple for repair of heat sink. I have had only 2 days since July that the thing has rsd'd on me. The first mabe 1.5weeks ago, being only 2 shutdowns before being stable and the next a week later being 6.

would you guys reccomend still sending it in for repair? i need my computer for work and school but also need it to be dependable. any suggestions?
oh and does anyone know hoe soon you have to mail in your computer after you receive the box?


also i found out there is an apple store in denver(close to where i live). could they replace it there?

thanks for taking the time to read my questions
 
Maybe Simply a Firmware Revision?

Hi

I don't post here much but I'm always interested in people's opinions on different aspects of the Mac world. I looked on here to see the general consensus concerning the SMC update and after reading everyone's thoughts concerning it I was wondering if it is just a revision of the original SMC update, and that in fact the old SMC update was the cause of RSD?

When I saw the first SMC update available I avoided it because some people found that if they didn't have fan problems before they suddenly did after the fix. I'm wondering, has anyone who didn't install the first SMC update had RSD?

I didn't install it and I haven't had these problems, so I'm thinking that maybe the RSD was in fact a firmware problem rather than a hardware one and now they've released this new firmware to rectify their fault.

Just a thought..
 
I have my Macbook since July and have never experienced a random shutdown.

My Lenovo laptop has no known hardware defect and thanks to wonderful software from Microsoft I do experience random shutdowns, lockups, bluescreens, you name it.

Given the choice between a Windows box guaranteed to crash, get infected and worm its way around the network, I'd much rather get a Macbook with a pretty stable OS and generally wonderful machine.
 
anyone experiencing random shut downs after the firmware update?

i just got my macbook back yesterday after waiting for over a month for them to replace the heatsink and then the topcase because nothing worked after the replacement.

i didn't realize that this update was out, and when i first tried to update, the computer wouldn't get past the grey screen then the vertical lines came back. i was about to throw it out the window. i reset the pram and it still wouldnt work.

i then reinstalled the update and so far it is working fine...i think what happened was i interrupted the update the first time. woops.

anyways, i would love to know how everyone's computer is doing now. anybody?

I'm definitely staying away from this update for now. Something about it actually just kind of scares me. It helps that my week 21 MacBook has only had the mooing issue and nothing else (so far). That issue has gone away with SMC Firmware Update 1.0, and I've had a great laptop ever since.

I feel rather lucky. :)

I don't get people who avoid important updates. I'd install it just to avoid future problems from forming. My MacBook runs fine with the update, and the fans are coming on less often as well which is appreciated.

Isn't everyone assuming here that the root problem is a heatsink issue? Has Apple ever announced that it was? Perhaps it isn't at all, or that's only part of the equation, and it is in fact an SMC control problem. There's a lot of FUD here - people saying they've had extra screws drilled in their MacBooks which is total BS.

I wouldn't try second-guessing Apple engineers. If they've released an update recommended to make the MacBook more reliable, I say use it.

Absolutely. I'm a bit surprised at all the misinformation (nobody is drilling a friggin' screw in your MacBooks, people).

Perhaps you've never been burned by one. I have. There's nothing worse than immediately downloading an update, then suddenly finding that a whole lot of things are broken that worked perfectly well before. Then you go to Macfixit and find reams of posts from other people in the same boat. Being wary of Rev A models doesn't only apply to hardware...
 
I installed Core Duo Temp bofore I updated my Macbook firmware. I got a logic board and heastsink replancement (and a lot more apparently... the list is pretty long, looks like they changed everything except RAM and HDD). Core Duo temp reported 10*C core temperature (90 % CPU at 2 GHz). It used to be in the 60s before that... After the firmwareupgrade the report was correct again (60*C).

PS: I have a screw in the middle of the bottom. Dunno if it has always been there. It could inded have been addd to hold the new (different) logic board and the heatsink in place so both won't touch ach other. But it doesn't look like it was added afterwards... is there anyon who didn't get his macbook repaired yet have this screw too? It's exactly in the centre of the shell on the bottom of the case. Just beeing curious. :)
 
Wow . . .

My MacBook was purchased in the first month. I did not have any random shutdown problems until the first SMC update.

Then I started getting random shut downs. All the %#(*&$#*($&^& time.

I took mine to Apple Store in MN, Southdale, and they fixed the heat sink within 90 minutes. No more random shutdowns.

The Genesis Bar dude went to console and looked for 2 items. They showed up. They took the MacBook. Fixed it and called me in 90 minutes.

My MacBook runs at 63c on a regular basis. I do have 2G ram and run 18 to 21 programs at once. I also have a cool pad beneath the kind with a fan beneath my MacBook that runs all the time.

Is this all the service they offered you? I contacted Apple when the RSS started to become a problem and was told that I could go to a certified Apple repair centre of choice.

I phoned one up who had already dealt with a former TIBook of mine and they said they would order the heatsink and get back to me when it arrives. My MacBook then got a date with the repair man the next day and the morning after I could go and collect it (new screw not included).

What I do recommend to everyone, is that they create a guest account WITH admin rights before they hand in the computer, so that the guys can play around with sleep settings and have a look at the system log.

The classic was of course iTunes 2.1, which sent one's personal files to /dev/null. Yes, all of them. And no, the Apple-paid recovery attempt wasn't successful.

Yes, I did have an update of the night before, but not of research data of that day.

Yes, the screw has always been there. Pictures were posted earlier. They're not sitting in the back of the Apple Store with power drills driving screws into the bottoms of your MacBooks...

I wish I had this many sensor readings. All I get is the themperature in once CPU core. :-(
Is there any kenel extention to install so I can get the hard drive temp (more important to me than the cpu) and the other stuff? Or the fan readings?

I have a stock black Macbook with some more RAM (see sig). PLease PM me if you know something for getting all the sensor readings.
 
I don't use the iStat widget, I use the intel core duo temp widget. Since I installed the firmware update last night, it doesn't seem to work anymore. Odd.

Is that the verdict on the screw issue?

I had my Blackbook in twice and the second time they replaced the heatsink (no problems since) but other than a slightly warped battery, I have not noticed anyother cosmetic changes.

If people are getting screwed they should post pictures (no pun intended). ;)
