UMBP excruciatingly hot running 9600m after 10.5.7

jeez i think i have 1st degree burns on my legs. For the first time after upgrading to 10.5.7 i switched over to the 9600M GPU I watched like 5 minutes of a dvd, then i was surfing the web and scanning a document I also had the Mail app running it was getting hot at this point but the real fun began when i started using handbrake to backup a dvd. the bottom and top of my MBP were like on fire. I've never seen it get this hot and the fans were going full speed. I think i looked at the temperature at one point and it was 142 F...... I dont know if thats really bad or not but it sure felt bad.
 
142F = 61C for everybody else

If that was the CPU or GPU temp (2 hottest components), then you have nothing to worry about, that's a cool temp under load. If that's your enclosure base temp, then you should get that checked out...
 
142c? Because 142F is only about 65c and that's cool... 142c is like 200 something F... Where are you getting your stats from btw?
 
i just brang up istat pro in my dashboard and glanced at it. I guess thats a normal temp but it felt really hot. Maybe because i'm a light user and dont really use anything heavy and intensive i wasnt use to it.
 
What is a suitable temperature under heavy use for the 9600M??

I was playing "Restaurant City" in FaceBook and my temperature would rise up to as high as 85C.. This is really disturbing..
 
Does the gpu make a difference when running Handbrake? Or is it the cpu carrying the load when ripping DVD?

My MBP was up at 120C and it really gave me a burn. Apple replaced that.

I really, really doubt that it hit 120C. The Core 2 Duo would halt at approx 100C (IIRC the max operating temp. is 105C, but thermal shutdown occurs a little before that.)
 
First degree burning is kinda....normal with a laptop from Apple. I have a powerbook G4 and under heavy load, I also have first degree burns if I have it on my lap. Alluminum conducts heat very well.
 
I must say my (u)MBP is running rather hot with 9600 since 10.5.7.... came home today and it had just been chugging away on Transmission all day and my room was really warm. All 4GB of ram were in use... Logged out/in and now only ~1GB free.... does seem a littttttle strange...
 
With an alluminium chassis you shouldn't necessarily put the Macbook on your lap with nothing in between when running CPU/GPU intensive applications. That's what alluminium does, carry away the heat from the inner to the outer.

The chips specs allow a maximum temperature of 105°C. Even after running stress tests for hours with a CPU temperature of around 100°C the computer wont crash. The GPU usually stays well below that anyway.

Besides, the fans are operated by hardware and thus run just the same on Windows as on OS X, at least on my late 2008 Unibody Macbook Pro. As far as I can tell they ramp up quite late and slowly after a longer Idle period. But after that they react quicker.

This is to make the computer quiet and nothing to worry about unless it gets too hot for you on the outside. In that case you're better off with using SMCfancontrol or some external cooling solution.

Just to mention it: iStat seems to read the CPU Diode instead of the Core temperatures. This usually is around 10°C higher than what's going on inside of the CPU.

Here is an example of the fans spinning up quite (too) late after when a "sudden" rush of load surprises them after a longer period of only small load:

 
Apple considers the MacBook Pro a notebook and not a laptop. At least that's what they I told me... Pretty dumb, I know.

Mine's also 85 C during load, which is a little hot imo. Can't decide if it's worth taking it back to Apple though.

That was my argument when I received my new computer. The computer burned some of the skin off my hand. Human flesh burns off at 130C. The temperature sensors weren't working correctly. The Core2Duos actually have an auto-shutoff at 125C.

85C "during load" is fine. Mine gets up to 85C when encoding movies or playing Call of Duty 4.

Does your 85C happen when using the 9400 or 9600? The environment also affects the temperature.. are you in a relatively warm room to start with?

Using the 9600, it was 85C after quitting 3D mark for 15 minutes... In a 20C room. It freezes after about an hour, sometimes two if I'm lucky, back in OS X. Fan Control can manage to keep it stable for a while longer, but using third party products just to keep it running ok...

Shouldn't be like that with a $2300 computer. I'm going to call Apple to try finding a solution when I can find the time to do it in a calmly fashion. I'm on my fourth already... 🙁

85C after 15 min of 3D Mark isn't that bad. You can try to call Apple.. ask for customer relations. They're the people who can actually get things done. I'm not sure what they'd do for you since your temperatures are pretty normal, but it's worth a shot.

You might want to tell Intel that. Their spec sheets say otherwise.

You could be right, but somehow I doubt that the thermal shutdown temp is 20C above the chips maximum temperature... 🙄

Almost all notebook manufacturers are taking the same stance given the heat signature of most modern notebooks. The term laptop will soon be phased out.
