Macbook Pro overheating problems.

i have a similar problem. My MBP stop responding after something..... random. Sometimes with the browser open on youtube, sometimes viewing some hd vids, sometimes on login prompt. The display freeze with pink, green and blue artifacts across the entire lcd, after a couple of seconds it becomes flashing, keyboard won't respond, same for the mouse. I'm must press on/off button to a forced shutdown. After that, i try several attempt to boot my mbp without result. It stuck on apple logo on startup with the spinning wheel running clockwise for a couple of time before stop spinning. Have you find a solution?

Why dont you try taking a cooler? I felt overheating too, but much less with cooler.

A cooler isn't a real solution to my problem. My MBP worked fine until now. Never a heating issue in the past 4 years so i'm considering the idea of some sensor failure or worse, a faulty logic board. I've downloaded iStat to check my temps but i really don't have another user information to compare my data. Can anyone could post some data about those temperatures? (those are mines)

CPU 40°C

GPU diode 54°C

GPU heatsink 39°C

Heatsink A 41°C

Heatsink B 34°C

my mac is a macbook pro late 2008 2,5 ghz intel core 2 Duowith 4gb ram, nvidia 8600M GT.

after many attempt to start up mu mac, i've realized there's something video related issue. Sometimes the video freeze but the audio still goes on. (Another strange think is the excess overheating during the start up. If i touch the zone near the eject button during the Apple logo and the spinning wheel, i can feel with no doubt there's something overheating inside. The Cpu works well (to me)....in temp terms. Any idea?

of course, i know that Apple can solve the problem for about $1200..... but IMHO, with those bucks i prefer buy another machine instead reparing an old one. If i can do somethng myself, i'll do the job...

Add me to the list. I too have a 15" Macbook Pro with the Intel Core 2 Duo chipset running Lion with all the latest updates. While my usage has not changed one bit, in the last month or so I noticed my laptop was running extremely hot. After it shut itself down once I have taken to using an external fan which works well. It seems to get the hottest when watching flash videos, but like I said, this is not a new thing for me. I am considering taking it in to be looked at, but after noticing the similar timing to your complaint I am wondering if it is actually a software issue caused by an update.

On the plus side, I have been able to stop running the heat in my office, as the computer seems to keep the room toasty warm all on its own. 🙂

I have a brand new MBP 15" as well that is overheating! I just replaced my one year old MBP. The old one never even got close to this temp. I am a little concerned! The fan starts running quite soon after I begin to work. It's almost too hot to touch just below the screen!

Very similar problem with my mid-2010 MacBook Pro. It seems to be graphics-related, so I've checked the box for automatic graphics switching. Still a problem.... and the box doesn't stay checked. Also turned off anti-virus scanning and a few more manoeuvres recommended in the forum threads. The temperature in CPU A reaches 95 degrees Celsius, at which point the machine shuts down. On occasion it has been impossible to manually shut down the laptop, had to leave it for an hour or two to cool sufficiently. On another occasion despite the lid being closed, it didn't enter sleep but continued to generate heat. There was no problem prior to "upgrading" to Lion, so I now have a dilemma - whether to wait for the June upgrade, since there'll be no more mobile-Me Mail, or change my email provider and go back to Snow Leopard.

So far I haven't seen any official Apple acknowledgement that there is an overheating problem with Lion, so it may be too much to hope for that ML will solve it. Helpful advice would be appreciated.

Run an Apple Hardware Test and see what that develops,.

Ciao.

about my experience in kernel panics, mbp 17 no boot, freezes etc etc, i would recommend an Apple Authorized Repair Center as soon as possible. there are many thing that can goes wrong. Gpu and Cpu becomes very hotter during normal usage and if there aren't some slowing down performaces, it seems normal. A couple of week ago my mbp 17 core 2 duo start to freeze sometimes. Sometimes very often. My first think is an overheating problem due to intense cpu and gpu works but after a while, i realized that is totally random. my mac can stay on in idle mode for hours and freeze as soon i open firefox or safari to load a youtube vid.... and vice versa. Smc gave me an illusion but if there's an hardware problem, soon or late, it occours again. to be honest, ear fans at 6200 rpm most of the time is kinda annoying and noisy. So i decide for the apple authorized repair center. they diagnose a faulty nvidia gpu and after replacing the whole logic board, my mbp seems brand new. it becomes hotter as a brand bew one but it's absolutely normal. it's a laptop..no cooling fan like many others but only 2 fan to extract hot air from inside to outside.... it have aluminum chassis and this work like a big cooling system.

there are many little pieces on the logic board and a faulty one can be a problem. A broken thermal sensor or a broken diode can compromise some other pieces to work in the right way. So, don't waste your time searching a band-aid to your problem.... take it to an official repair center.. they know how to solve your problem.... at least, they do a try :)

This thread is over a year old, but it popped up #1 on my google search, so I thought I'd share my experience in case it's relevant for anyone else.

I have a mac book pro with 15" retina display and it was running cool as a cucumber until a couple of days ago. I also noticed the battery draining much faster than usual.

After researching I checked the Activity Monitor and sure enough there was an application reporting 200% CPU - not a typo... 200% CPU.

It was Open Office.

I killed it and 15 minutes later I'm back to running very cool.

Since people seem to be looking at this thread, I found something that seems to work for me.

It allows you to set a higher default speed fan, it really made a difference for me.

Summer's not a good season for computers T_T
