Yeah, that's in the "Energy Saver" settings. Unfortunately, unchecking it isn't exactly a benefit:

It just uses the nvidia GPU by default, never "downshifting."


There is a bug in this part of the OS. This setting should be mutually exclusive between Battery and Power Adapter. However, checking or unchecking one affects the other.

I think the next release of osx should fix that
 
I tried handbreak again, and CPU reached 100C and CPU Heatsink 56C. Then fans kicked in with around 4300rmp, CPU temperature dropped to 83C and CPU Heatsink to 53C. I would prefer fans to kick in before it reaches 100C, But for now i think i will control fan rpm myself when i run CPU Intensive applications. When running non CPU intensive application it runs pretty cool around 40C.

Next I tried yes > /dev/null, CPU temperature reached 97C and CPU Heatsink 56C. Then fans started spinning at around 5100rpm and CPU temperature dropped to 88C and CPU Heatsink to 52C. I dont think there is anything to worry about.

And one more thing that i forgot to mention, when i was running both tests I was charging battery in the same time

Thanks for the info. All seems to stack up. As you say, I don't think there's anything to worry about.
 
So what is everyones normal operating temperatures? farenheit and celsius please.....My fans never go above 2000 rpms and my temps been as high as 150 farenheit....

That isn't hot. don't worry about it. 200-215F would be hot, and your fans would kick on way past the resting 2000 rpm.

Even though they don't say it's Celsius, 50-75 F would be way too cold for these CPUs.
 
I've been running my i7 MBP for seven days now. I do 3D Aerospace design with an app that is very demanding of system resources.

My mid 2009 MBP would run for two hours before getting so hot I would have to shut it down to let it cool.

Not so with the i7 I have now. It runs very warm but _not_ hot and that's after seven hours of pushing it hard. This is a very impressive machine, the dual fans do their job and come on at the appropriate time, with little noise. I am pretty picky and I must say I have Zero complaints with my new MBP. I could not be happier...:)

This is very good news considering I ordered the MBP core i7, just the day before "PC Authority" released their "shocking discovery". I can finally sleep again.. :)
 
Also, does anyone know the age these mbps vaguely get to without something breaking. Only thing that has ever been replaced through an actual fault and not cos i wanted it on the tibook was the battery *:)

Hard to say. I had an early 2007 15" C2D that lasted me three years without trouble. On the other hand, the iteration of MBP right after that had known issues thanks to nVidia and bad manufacturing processes with the 8600m GPU.

The new GPUs and processors in this current generation means another design change. This shouldn't cause problems, but only time will tell.
 
How hot will this thing run compared to my tibook ??
I cant find a temperature monitor which works, and the fan in this thing is either on or off, with the bottom casing getting burning hot :0 before the lonely 2cm fan trys to make it a little cooler :D

Thanks in advance

Btw, ive just ordered a standard 15' i7 for £1250 w/printer applecare and remote :D
I too have a. G4 TiBook 1GHz/1GB, that has served me very well. I bought mine at the Apple Store in Palo Alto the day they were released. To date it's the one PowerBook / MacBook Pro of all that I've had, that has never had anything break. In fact relatively speaking all my PowerBooks were great. It's just that the TiBook was the best and my favorite.
The ongoing heating issues with the Unibody MBP gives me cause for concern due to the fact that even if they do not overheat, Apples standard for "normal temps" is so high that it's certainly going to impact the overall life of the computer.
.
Being platform neutral and working in the industry I use OS X, Linux, and Windows 7. I enjoy them all, yet have a slight preference for Apple. I wish they would supply us with a computer that is commensurate with the price they charge.
.
I have two new laptops this year. They have the same Core i7/ 4GB/500GB7200 basic configurations. One is my ThinkPad T510 & the other my 15" MBP. I don't believe that one is "better" than the other, just different. My personal preference is the MBP, and yet it does bother me that it runs much warmer. Heat is the enemy of all things electronic, so it would make me very happy of Apple would get serious and design a cool running MBP. Lenovo proves it's possible, and my T510 is still only 1.3" thick. I wish the MBP was 1.2" thick, with a great cooling system and vents in the side of the case like the T510, the Apple would last longer as well as run cooler.
.
When one considers that Apple charges such a high premium, it would be really great to know that you were truly getting the finest laptop, instead of just another of the top tier machines. The facts prove that cash rich Apple, prefers profit taking over spending a bit more to deliver the superior product their marketing machine makes all things Apple out to be. Especially since I really like Apple, I'm a loyal customer of many years. Having used ThinkPads & PowerBooks/MBP side by side for years, the biggest impression I'm left with is the reliability & durability of ThinkPad is stellar for far less money. I wish they were equal.
.
Cheers

I think Apple gets you on the little details... like the so far unduplicated (as far as I know) trackpad. Holy crap, it's SO difficult for me to use any other computer now.

It's "little things" like that, things that you soon can't live without, where they getchya. :)

Point taken. And that's why I wish they would deliver the "complete package". I also pay a premium for the new BMW I drive, and they _do_ deliver. So, in this case the point is I wish Apple would.

If anyone wants to go one step better than iStat and actually test how much heat gets transferred the surfaces we humans TOUCH, grab an Infrared heat gun like this:

http://www.amazon.com/Fluke-62-Mini-Infrared-Thermometer/dp/B000MX5Y9C

That's similar to a IR thermometer I actually took into the Apple awhile back to Mac sure I wouldn't get a computer that scorched me. I really don't think the Macs from the past few years have as much of a problem, though.

The thing is, you do get "lemons"... These things are made in China, after all, a country which has proven that it will kill children and seniors alike by putting melamine (basically powdered school table) in milk if it means saving a few cents.

http://www.youtube.com/watch?v=ZBpAknlu0TE

This is a country that desperately needs to return to it's vastly more ethical roots.

True lemons aside, in my in-store IR testing of Macs, I saw all the computers were a bit different temp wise, even from a fresh boot...

The sloppy way the $120/mo Chinese (slave or pseudo-slave?) workers apply thermal paste has a lot to do with this. I'm guessing the folks over at PC Authority in Australia got a machine with too little or too much (more likely) thermal paste applied, which made their computer excessively hot. They should exchange it. Apple, btw, will easily exchange anything the moment you whip out your IR gun to prove a point. :)

Hello.

Really need your advice fellow mac users.

I got my Macbook Pro 15 " with i7, 7200rpm hdd and hi-res last week and I confirm that cooling doesn't do a very good job here.

During normal use it floats somewhere between 35-45C. Once I launch video conversion or a 3D game it jumps up to 95C and then going down slowly. Fans kick in really late. I have lastest version of iStat Menus which has minimum fan speed overdrive option (2000-6000rpm). If i set it to 4000 it never gets past 85C. So, I called Apple and described the problem and they said they are NOT aware of that issue and when I told the guy that by default fans run at 2000rpm @ 65C he was quite surprised and said I can get a replacement.

I really need your advice on if I should get a replacement or wait till they will be aware of the problem and release the driver update because it is most likely a software problem. I did not have any problems with my previous macs, so i don't know how to deal with it now. It would just suck to wait for replacement for 14 days and get the same thing.

P.S. Oh and probably you guys who have the same issue (i be all of i7 owners) should let Apple know about the problem so they would actually take care of that.

What exactly is the problem? Is the MBP getting too hot to touch it? Is it overheating and turning itself off?

I really don't understand these complaints. It's well within Intel's recommended operating temperature, yet people get scared and call Apple when they see the temps climbing to 90 C when using something that is CPU intensive.

That's standard MBP fan behaviour, I think they all do that. Lots of threads on here about it. There was another i7 thread discussing in more detail. If you got a replacement I'm pretty sure it would do the same thing. My 13" C2D does precisely the same thing, so do others I've seen.

Apple seems happy to let its CPUs run hot - that's just the way Macs are. I'm not aware of any reliability issues coming out of it.

As MBHockey says it's all within Intel specs, and I believe your Mac is behaving the same as millions of other MBPs out there.
 
Well to me it was a big surprise that cpu runs at around 90+ degrees, it is actually my first mac that does same thing.

What is really interesting then is that the Apple guy who talked to me would strongly disagree that it is normal and he also said then it is not normal when fans run at 2000rpm when at 65C.

I am not gonna go for a replacement for now, 'cause if it fries itself, it is gonna be replaced anyway, but I still think it is a good idea that more people are gonna contact Apple and let them know that their fan control software sucks as of now, well at least for i7.

It is within the specifications (up to 112C) but it is still harmful temperature for electronics.

Ok, so it's a big surprise. Doesn't mean your unit is defective.

Still harmful for electronics? Says who? You?

Apple designed the MBPs. I'm pretty sure they understand how hot the internals can get before it's dangerous.

And you do realize that every MacBook Pro ever has had a resting fan speed of 2000 RPM right? The "Apple guy" has no idea what's going on if he granted you a replacement for a MacBook Pro that has its fans running at 2000 RPM as its default setting.

Lot of craziness over nothing in this thread.

Its not China's fault about the thermal paste problem. Apple even shows a absured amount in their service guide. Other manufactures like Dell, Sony, gateway, hp make their gadgets in China, and while they use poor quality (Apple included) thermal paste, these other manufactures apply the correct amount. My Latitude D620 was built in China by Foxconn, and so was Apple's MacBook Pro. One had thermal paste applied correctly. I've never seen a PC with mis applied thermal paste. Only Apple computers.

After reading that, I did some testing using handbrake and it was indeed hitting 95+ degrees and no indication of the fans speeding up automatically.

Downloaded SMCfancontrol and manual turned it up, on max fan speed, the cpu never peaked over 64 degrees under 94% CPU utilization with 6000rpm fan speed.

a COUNTRY that is willing to kill children and adults??? cause a few greedy people at a company were corrupt? I thought we were just talking about heatsinks here. Thats like saying the U.S is a COUNTRY that (insert well known crime committed by someone/a small group).

As mentioned in my previous post I think the problem is that apple has set the fan speed to kick in a bit late, maybe with a new update it will be fixed by software. :rolleyes:

my MBP i7 15" is fine! it runs cooler than the previous 2,8 C2D MBP...

That's interesting. I was just about to post the opposite. The April/10 i7 15" MBP that I've had time with runs hotter than an '09 MBP, 2,8 C2D, 4gb ram, ssd.

I'm talking about doing light tasks, web surfing, emailing.... there's no question here the new 2010 is much warmer on the bottom and the fan runs more continuous that the '09 2,8.

Anyone else have the same experience?
 
@ koruki, Kizzmansky

It would be great if you could post your findings on here
https://forums.macrumors.com/threads/908210/
That way we can get more data on how MBPs behave

As you can see, a whole page of i7 users who experience the same temps as you. If you search on these forums you'll also find people who see the same thing on i5s, C2Ds.
