New 2011 MacBook Pro Heating Issue?

I am deciding weather to get the 2 or 2.2 ghz, the 2.2 for 270 au more I get a way better gpu which makes it better value for money to me but if there is 10 C difference at idle (macrumors reflects this) this could sway me to the 2 ghz 15 inch not to mention this would equate to a slightly longer battery life.

can someone confirm this?

I dont need the fastest as it will blow my 2.4 core 2 out of the water but I do need it to be cool/quiet when not being used heavily.

does anyone think there will be the possibility of an app like coolbook to underclock the 2.2 ?

then I can have the best of both worlds 🙂

I just updated to 10.6.7. and from a first point of view it appears to address the issue.

Just did a video conversion again, watching istat closely. Impression: it takes a little longer, till the cpu's temperature is rising (i'd say a minute compared to 5 seconds before the upgrade) and it rises only to a high 70ies°C - low 80°C. The fans set in later, going to a max of 4700 rpm, not 6200 as before. The video was converted at the same speed as before updating.

Again, this is just a first, quick look, but to me it appears that the update seems to improve the situation.

hi i got mine from hong kong as well and i haven't encounter any of the problems that you mentioned. but mine also vibrates a bit when it was being charged. the first thought that i had is because the electricity here in my country is not grounded, hence the current is passed through the aluminum encasing making it a bit tingly. hope that helps yours, and try updating it to the new os to solve your problems.

Hey guys,

Right now im still on my Mid-2007 MacBook, so im used to high (112C) heat and am ready to upgrade.

Would it be possible for some of you to run a test for me? Right now I have to do a lot of work in Windows 7, and much of it involves rendering. On my Mac I have RealTemp installed to tell the temperature, but it also tells clock speeds. When my Mac reaches over 85C, the processor clocks down to 997Mhz, which is painfully slow and all the projects take forever to complete. If any of you have Windows installed, please get Prime95 and RealTemp, run a stress test, and post the results if it downclocks or not. It would be extremely helpful!

One more thing: My max sustained load temp in Windows is about 85C but in OSX it goes well over 110C...could it be its not downclocking here?

I'm thinking of buying a macbook pro soon, reading this is really turning me off it 😟 Any official statement from apple on this as to whether it will be rectified soon?

remember, for every person who posts something bad here there are thousands who arent having any problems.

Yes they run hot under load but so does any other laptop with 4 cores and the heat that come with them..

Im just waiting for a minor revision just to make sure then I will get one me thinks.

I wonder if Apple will put out a revision before Lion is released.

Like others providing answers. My new 13"i7 fan is really loud and the unit is way hotter (and louder) than my old MBP 15" 266. I don't play games but do use video conferencing. But just using mail and powerpoint the fan & heat cranks up which slows down the system. In fact, I'm getting the "beach ball" far too often for an Apple product.

Watching netflix on a single chrome tab spiked up the temp....
(No other app running except chrome.)

CPU 196F.
GPU 166F
GPU Diode 171F
Heatsink B 160F
Enclosure Bottom 101F
Memory Controller 112F

Insane!

It sure is, if I cant so something as simple as surf the net and watch movies in relative coolness/quietness then I may as well just keep my old core 2 and put my money back in my pocket and wait for Ivy bridge. (so sick of waiting)

😟

Id be submitting feedback on it, they cant fix what they dont know about..

I wanted to follow up on my earlier post having used my new MBP 13" i7 for more work.

Overall it continues to run cooler than my old MacBook Aluminum 2.4 GHz did. However, I have at times seen it quickly jump to 90-93C, fans at 5k-6k, while doing something CPU intensive. My theory is that it is responding to the load with turbo boost. I've tried not to worry about this and the temps do fall back down quickly after the task is done. As an example I've seen this related to an errant program I force quit and to reboots of my WinXP VM. NOD32 seems to go nuts for a couple minutes after an XP reboot, and I wish I could throttle back or kill its startup scan.

I've also noticed that LogMeIn is good for a 15C boost in temps while other remote desktop apps (MS and Apple Remote Desktop; VNC) do not do this.

Judging from the contrast between reports I wonder if there's a hardware issue going on or if it really comes down to a user's work profile. And if it's related to specific software or tasks, could Apple give users an option to throttle back the CPU if desired? I'll admit, I would be irritated if it hit 93C on my lap. (It was on my desk at the time.)

It really would be ideal to be able to tell the machine when it needs to run as fast as possible, and when it needs to run as cool and silent as possible.

Still, in contrast to most reports, I'm pretty happy with the i7 and Sandy Bridge. But it's not just a matter of running cooler, it's a different profile. Cooler most of the time, but peaks more easily and higher.

Just ran an interesting test. I watched a 720p YouTube video with smc controlled fan at 2400 rpm.

* At first the temperature climbed slowly but surely, over about 3 mins, to about 82C but the fan never went higher in rpm.

* Then the temperature dropped, same pace, over the next 3 minutes down to 55C.

Video playback was never interrupted. I'm not sure what to make of this. Turbo boost engaging and disengaging? Different processor loads for different portions of the video? (The video seems like it would have been pretty constant in terms of compression.) Flash quirks?

I tried to capture the same on a screen-recording in case apple wants to see it. I started from 138F, went upto 198F, which I don't mind, but being around 198F constantly for the entire screening of the movie (around 1:30), that is ridiculuous. And this is just netflix... i can't watch netflix on my $2300 laptop?

Try to watch this n 720p mode.

Just another note: watching a different, longer video at 720p full screen ended up with my MBP at 80-83C and 3600-3900 rpm. Not crazy about that.

However...using the HTML5 beta version of YouTube to watch the same video at 720p full screen left me with 55-60C and 2400 rpm. (Note: 2400 rpm is my minimum fan speed in smc.) That's a non issue and was, in fact, the idle temperature with my MacBook aluminum.

To say that Flash ***** and needs to die is an understatement. Still, Apple should provide some way of throttling the CPU to keep temperature and noise down as there are multimedia and gaming applications which are simply going to drive up temperatures, but could probably run fine at a lower GHz. That would solve most user complaints. The rest might honestly fall into the category of "this isn't really a notebook app unless the notebook is on a desk with a cooling stand." There are some limitations to a tiny, closed up case.

Perhaps this is a shareware opportunity?

Well I finally got my mbp 17 inch 2.3 GHz i7. I ran a few heavy programs like parallels with Win 7 and Ubuntu at the same time along with, chrome, itunes and candybar. While they all were running I used istats to see the temp, it started to get hot and I could hear the fans come on. I did not have any of the problems that others on here are having. The computer continued to work flawlessly and the highest temp it got to was 190. Now I did have an earlier question that no one was able to answer and that was if anyone is using a cooling pad and still having these problems? I use an APC fan underneath with the unit directly pointed to where the processor is. I can say that it keeps the underside very cool while running all those programs and when the temp hits 190 and the internal fans come on revving up to 5000rpm it quickly goes back to around 140 degrees. So after doing these tests on my own with the cooling pad underneath I have had no problems but as pointed out earlier not every unit will have this problem Oh I am also running 10.6.7 which also makes a difference.
