I just ran a test on my SR MPB, and the CPU temp went up into the 90's(C) after a few minutes, however the fans didnt ramp up until the CPU temp reached 93 degrees C. If the fans aren't coming on until the CPU is that hot, then it seems obvious that the CPU is perfectly capable of dealing with those kind of temperatures, right?
Got a tip for us?

Actually your completely wrong and your post demonstrates your absolute ignorance. A complete and comprehensive review was carried out on the Apple manufacturing compunds and they were found to be of very sound quality, facillities and employees were treated well. Contrary to your ignorance.... it is no sweat shop and they certainly do not employ 7 yr olds!
On to the thermal issues....what is peoples problem? since when is 60C hot?
There is resarch going on at the moment that i have access to that is looking at the relationship between temperature of components, use and their failure rate. It looks at the moment that the components that are running cooler or the ones running in extreme temps 95+ hae higher failure rates than those running 45-95. Google also produced a white paper with similar reulsts from the hard drive world.
If you're at 93C, your CPU is only 7C away from automatic hardware shutdown in order to prevent permanent and immediate processor damage.
If your MBP had been properly designed AND assembled, it simply should not be running in the high 80s or 90s. Your desktop does not do that. Other laptops do not do that. It is most likely due to sloppy quality control + thermal paste application by Apple.
Take your MBP back and demand repair or replacement.
If you read the rest of the thread, you'd see that the SR MBP CPUs are running, oh, about 50% higher than the 60C number here (when tested under full load, as they should be tested). If they ran at 60C, this thread would not be 3 pages long.
I read the thread..... my mbp is at 90C now encoding a video but you don't see me crying like a little girl. IF YOU read my post you would see its fine.
at the end of the day your sticking the latest greatest cpu and gpu in a mobile device into under 1" thick enclosure..... if its too hot for you go buy a desktop or a thicker laptop from another manufacturer.
Your temperatures are within spec..... go cry elsewhere or return your laptops and buy something else.
I guess you shouldn't have set up that straw man about 60C then. I believe you that your MBP works. Defend Apple all you want -- I like their products too -- but running at 90C means that it's not working as their engineers had intended. I bet you have a crappy thermal paste job too. That will take time off the life of your system. It's hotter than any other laptop out there, and Apple should repair it. Enjoy!
This laptop coud be from any manufacturer and i will say the same thing! As for reading, your clearly incapable....the latest reseach shows that these temps DO NOT cause shortening of life!
EDIT: as a newbie here you need to learn to show your edits and stop making them when people are posting! I have already explained to you why these laptops are hotter than others....if you dont like it buy a brick from Dell and get the temps you want.
EDIT2: Apple like me will also say its within spec.....which it is.
I really don't care how high your postcount is; you've provided no documentation at all to support that these laptops are operating "within spec" or that about how the high temps aren't shortening the life of the product. Your vague references mean nothing.
I bet you defended Apple the last time there was a big outrage about thermal paste application and MB/MBP temperature. Yet, Apple responded to those problems. Because, the fact is, THIS IS A PROBLEM. 1" form factor or not, the CPU should not be hitting 90+ degrees C. Sorry. Keep defending, fanboy. Sometimes, even Apple gets it wrong.
Mine does the same thing too, the fans don't rev up until 90 C. However, that's only the CPU temp whereas the laptop itself doesn't feel extraordinarily hot compared to my CD MBP or C2D MBP which ramps up the fan at about 70 C. It actually is about as cool as the C2D, and much cooler than the CD. If anything is needed to improve the fan speed, it'll be thru software, either an update to OS X or a firmware update. I have noticed that the fans spin up more quickly under Windows Vista though.
Anyway, I don't think it's a problem. The computer doesn't shut down due to heat, nor does the speed throttle down. I'm not worrying about it.
I cannot quote you references as it confidential research.....you see if you read my profile you will see i am a research engineer....i specialise in Condition Monitoring....do you know what that means? Sit comfortably let me explain.... It means every day of my life i experiment and research condition monitoring of all the little components that make up your little laptops. Therefore i can tell you your point is mute and crap. Sorry i cannot provide you with documentation.....i will post the thesis when it is finished!
Secondly i referred you to a google white paper on hard drives. If you are enept enough not to be able to use google to find it then sorry for you.
Regarding specifications:
http://processorfinder.intel.com/details.aspx?sspec=sla43
upto 100C is within specification....though obviously it would be common sense to say that 99C is the limit....if like me your CPU is at 90C at 100% load your laptop is within spec. If its like that at idle then sure you have an issue.
By the way. Your new to this forum, bit of advice. Don't cry apple fan boy to people it doesn't go down well, you don't know me. I have been through 5 Rev A macbooks and pulled apple through the dirt on it. I brought in the papers/press and websites. I even had a call of the VP! So i am no apple fanboy and am happy to say they get things wrong....leopard is a prime example. Oh and that proves your point wrong about me defending them last time.
However i can tell you for a fact being heavily involved in the Macbook issues back in Rev A days Apple will tell you it is within spec.
That's weird... For me, Vista seems to take longer to turn up the fans. And the computer always feels hotter overall when I'm running Vista, too. Like, I'll just be using Firefox or something, and it gets very hot, both underneath in back, and between the keyboard and the screen where there's a strip of metal. It gets hot to the point where it almost hurts to touch it for any period of time. Also, as I mentioned earlier, my computer has frozen (now 3 times) when I was playing Battlefield 2 on Vista.
Right now I'm running CPU Test. My settings are: Test type: Big, Repetitions: 1000, Instances: 2 (for dual-core). I'm monitoring my CPU temp on the iStat Pro widget. And at first, it started heating up fast and the fans weren't even kicking in. Then it reached about 93C and the fans really started up then (they were around 2000-2500 rpm before that). It reached 94C at one point and then started to cool off. Right now, it's at 79C. It was staying at about 83C consistently for a while a few minutes ago. I don't have it on a cooling tray or anything, it's just flat on my desk. What do you guys think? Does that sound like a faulty laptop to you?
EDIT: What's weird is, when I felt underneath my computer just now, it still didn't feel as hot as it did when I played Battlefield 2 on Vista. Of course, the CPU temp has been reduced to around 80C by the fans so it's not still at 94C, but still...
I am actually quite dissapointed by the lack of improvements in Leopard. I would have expected some more interesting secret features but as far as I'm concerned it's a minor upgrade from Tiger...
Probably they have put too much time and resources in developing the stripped down OS X for mobile devices (like the Apple TV and the iPhone). While this mini OS X is nice they should have put the same effort in Leopard development.
1. Your 'research' credentials mean nothing here. You don't work for Apple, and you can't even spell "inept."
2. A widely circulated Google paper on hard drives has nothing to do with CPU temperature in MacBook Pros.
3. I had previously mentioned that the CPU would run until 100C, at which point it goes into automatic hardware shutdown. That is not the operating temperature for which the MBP is designed. If you look at the data from some people with apparently decent paste jobs, or the person from the original post who reapplied his paste, CPU temperature under load should be near 70-75C, tops. Temperatures of 90C or higher indicate a problem. Apple engineers design the cooling system for the MBP, and you can bet your bank they didn't intend on the CPU being at 90-95C under load.
EDIT: kingofkolt, if your CPU gets up to 93-94C before the fans bring it down to 79-80C, I wouldn't want to own your laptop. I bet you can open it up and discover a crappy thermal paste job.
Do you think it should never reach 90-95C, or never stay at that temperature? As I said, my computer reached 94, but it quickly went down once the fans kicked in. I'm running CPU Test and the CPU usage says 96%, and the temperature 78C. Do you think that's abnormal? (You said 70-75C under load, but do you mean under 96% load, or around 50% load, as a game might use?)
No but i do work for relevant people to the contents of this thread
WRONG. A hard drive is a component of a PC/laptop as is a capacitor, CPU, GPU etc etc. Again research a colleague is doing is based directly on the google work and confirms those results on components such as CPUs and GPUs hence a CPU running at 90C is not having its life shortened as you so vermontly swear!
No where in this thread has anyone posted that their MBP has run up to 100C and shudown so your point is not valid. I have not once said there is not a poor paste job, infact i believe there is, machines do this task in a factory, **** happens. Apple engineers will have recieved these machines from the producion line months before release ad apple will test hundreds in their labs prior to release. There is nothing wrong with a MBP running at 90C under prolonged 100% load.
I can't get it through my supposedly thick skull becasue i do this for a living i know there is nothing wrong....aparently you just troll forums for a living slating apple and posting about macbooks you dont appear to own.
Okay, well, research a colleague of mine is doing says your colleague is wrong. What a great way to conduct an argument! Unsubstantiated claims to mysterious research! A hard drive is very different from a CPU, sorry.
I'm glad we agree that there are poor paste jobs out there. Apple should fix the problem. That's the point of this thread. As for the 90C comment, you're still wrong. Further, I imagine the thermal paste application is done by hand. Sloppy, inexpensive labor. Poor quality control.
Does this not bring back memories for people?
http://home.sc.rr.com/mixedbag/MBP/Photos.html
This is an old problem. It was supposedly fixed. It's back.
EDIT: by the way, "engineer", if you actually read that google paper (I have), it has no data on hard drives for temperatures above 50C. It's still totally irrelevant to this discussion.
http://209.85.163.132/papers/disk_failures.pdf
Oh yes must be wrong because it doesn't agree with you
Funny as all the data appears to prove he is correct. It also backs up the google data. Will let you live in your own little fantasy world, all you have done is provide a few members with some entertainment.
Oh and if you did anything meanigful in life except trolling then you would probably appreciate NDA's and confidentiality agreements....
Agreed
No i just don't agree with you. I have far more years experiance in this field and know far more people in industry to know what i am saying is correct. Again if you want to live in your bubble so be it.
WRONG. It is applied by a machine. Has nothing to do with the labour but agreed better QC is needed.
While it may be uncomfortable if its on your lap (although Apple say to not use MB/MBPs on your lap-I'm running my MacBook at 100% on my desk now); there is technically nothing wrong with a 90C CPU at 100%. At 100% its not gonna get any hotter, and 90C is within specification. And besides, the CPU has a temp. diode in which shuts down the machine if it gets too hot.
It should be noted that according to Intel's own specs, the CPU temp should be below 50 degrees C or 35C in order to "sleep", or "deep sleep", respectively. A sufficiently crappy thermal paste application could prevent your CPU from accessing its power saving "deep sleep" feature.
Yet another reason the target temperature set by Apple for the CPU of the MacBook Pro is an important quantity, apart from the maximum possible operating temperature before thermal shutdown as defined by Intel.

Proper MBP paste jobs see CPUs under load operating near 70C. That would seem to be Apple's design. In my opinion, anything else is defective.

Just ran two 1080p HD Trailers on my SR MBP, and the CPU Temp went up to 95°C, with Fans spinning at 2800rpm. Then they started to spin up to 6000rpm, and the temperature was stable at 81°C.
Btw. I was running the MBP with the power cord connected to it.
Edit:
When stopping QT for a while, and starting the two movies again, after the CPU temp did get lower, the fans immediately started spinning with 6000rpm. So that initial delay mght be to prevent fan on/off behaviour?
Edit:
The room temperature was 27°C

I find it interesting that this information is based on a study that came out in 1999.
Temperatures vary by processor and type of hardware. This is an interesting read...
http://users.erols.com/chare/elec.htm
From my experiences, just about everything with a circuit runs on the higher side of normal, there are too may factors and environmental differences to determine that running 90c means there's a problem. I find it very hard to believe that you'll be running between 70-75c most of the time, unless your just watching your screen saver all day. Anyone who actually uses their MBP for something productive for any extended period of time (meaning more than an hour) is going to notice it is heating up, that's perfectly normal. Now if you see smoke coming out of the air vents, yeah, you have a problem, but don't go running up the red flag just cause your laptop feels a little warm in your lap.
Please quote page references.
The document does however quote a temp i forgot to earlier and that is the damage temp of 125C..... so even if you macbook did run to 99C it would not experiance damage and according to research no significance in life span....though that is what i have been trying to say all along
huh? Who's talking about a 1999 study of CPU temps?
Nobody's doing that. If you read the thread, compare reports of good paste jobs (and specifically the links in the original post), to things like the previous post (95C while playing video, which forces an emergency fan kick up to 6000 rpm)... you may be able to figure out why this thread is 4 pages long.
pages 75-76 in the pdf I linked, look it up. After all your posts you haven't given any evidence in support. I give Intel .pdf's and experimental reports from people who've changed their paste jobs, pictures of obviously horrible paste jobs from past and present. It would be so nice if people didn't feel compelled to defend Apple.
