MacBook Pro Overheating [FIXED]?

I think i found a solution and the reason to why the macbooks are overheating. The cause? The CPU is doing all the work.


I watched the cpu and gpu temeratures. My GPU never got too hot(50 c at max?), basically just the heat from everything else heating it up. Meanwhile, my CPU will be up at 80-90 degrees celcius.


System Preferences > Energy Saver > Uncheck Automatic Graphics Switching.


What happens (from my understanding) is that to conserve power, it uses the CPU to do the work of the graphics card, and of course is rediculous when running HD flash vides and such. Unchecking it will force it to always use the GPU. Which, takes a heavy chunk off that CPUs load.


Try it out, see for yourself. All it is is a simple box to check or uncheck if it doesnt do you any good.


For me - It seems to be a lot cooler now that I unchecked that.

MacBook Pro, Mac OS X (10.7), 2.66 GHz i7 (1st gen) 4 GB RAM +SSD

I have tried al the mentioned above tricks.. but no benefit....


After searching the whole interenet and apple community forum, i am surprised to see that there is no response from anyone in apple.. dont they periodically check what apple users are facing.. ?? dont they monitor the community so that they can fix the issues before it gets out of hand.....


I had a very good impression abt apple. until before upgrading to Lion...


NOTE: My MacBook Pro 13 had been thouroughly checked in apple serivce centre and no hardware issue had been found for the heat issue... so its LION only... crap my MONEY IS GONEEE

Sorry to tell you man (or lady) [no offense 🙂] but...

I'm running a Macbook Pro 2.4 GHZ i5 (the model that came out right before the one with thunderbolt).

and I'm running OS X 10.6.8........... Snow Leopard.


And I am having the same overheating issues.


I've been using smcFanControl to control the fan speeds, but it's getting a little rediculous lately. I noticed that using VLC streamer (to stream to my ipad 2) uses up a LOT of CPU power for some reason and the temps on my macbook go through the roof.


I tried the OP's solution above but it didn't help with the streaming.


I've searched this up before. it is a hardware issue. It has to do with the heatsinks or the CPU. (BTW I'm totally making up terms because I'm too tired right now to hunt that thread down, sorry) basically the coolant (cooling) glue / gel stuff that goes on the CPU is super cheapo shtuff that looks like bird do-do. crack open your macbook pro, scrap it off and apply some high-end stuff and your macbook pro won't over heat again. (thats what people were saying anyways)


so I just wanted to give you a little good news bad news. However, since this is techically my fiance's laptop, she won't let me crack it open to fix it.


So I'm still looking for a software solution myself.... I'll try to report back here if I find anything.

AFter reading this discussion i have to assume all the lockups ive been contending with are due to overheating. I got my 15 mbp in december 2010 from an apple store in tysons corner, VA. this was the second one i got in a week. The first one was devastatingly defective with a graph card on the fritz. Called ac yestereday they had me do an smc and that other reboot thing, holding down keys. Did me no good, no surprises. Typing this on my ipad, since the mbp has become useless most of the time. Will call ac again for the next rounds of tests and report back. This Overheating issue (and the apparent lack of a purposeful response may call for a user-wide response against apple computers. They have deceived us and we need to do something about it. Apple lies. Look at the foxconn event. Theyre no better than an exxon mobil or a nike. Cheapest manufacture for biggest profits. Sorry to be politicizing this but dealing with lockups on my work mpb for one year. My quality of life suffers since i spend 90% of my day with this mpb. 15 years on dells before, never had a single problem. Thinking of powering up old dell again.

After my last post I decided to download that smcfan software, switch off the automatic graphic switching again, not the MPB plugged into the power all the time (I guess that causes overheating, too? please confirm) and see what happens and not be such a cry-baby about it. Defects happen; what I get angry about is that Apple never ordered a recall or made any significant overtures to resolve this situation on a grand scale.


i'm just saying

Thanks for this super-tip.

I have a 2011 MBP and have been experiencing this overheating issue way too much. The computer is fast with a SSD, but still hangs too often.

1-2 hrs after applying your tip, I found that the CPU (measured with iStat Pro) is down to 65-68°C from a before 79-85°C. The worst parts are always the flash animations/videos. The come up with almost every website and consume way too much computing power.

Since I use the MBP mostly on my 27" Cinema Display, it plugged in 90% of the time. Only 1-2 a month a use it not at my desk, so I wouldn't even need it for now....(this feature)


Thanks again!

I have been having similar problems with my 2010 MBP 13". It always ran a little hot and I had to place something between it and my lap. Recently it started shutting itself off randomly. So after reading several discussions about similar problems, I downloaded Fan Control 1.2. After you install it, you can find it in the System Preferences. Amazing results! My computer immediately dropped in temperature. The CPU Core Temperatures went from 85-90 degrees celcius to 39-43. My laptop is nowhere near as hot as it was. I also followed the advice of one poster who adjusted the settings slightly, but it honestly fixed the problem immediately and without any tinkering. I'll repost it my problem reappears, but at this point I think I spared myself a trip to the genius bar and several hundred dollars.

hi...


i have resolved it by downgrading to Snow leopard..


It seems apple doesnt care to reply our issues or Fixing it with upgrades also..


seems Lion is more resource hog that the Macbook pro cant handle..


also to consider Lion doesnt have much features that will stick u to it....


just some extra animations /interface for normal users like us.


i had downgraded my MAC to snowleopard some months back and its running very fine.. no heat issue ..


just dump LION... i paid for LION but seems like waste since APPLE doesnt care abt fixing issues that users face with it...


best of luck.. if u need any advice reply.. 🙂

I have same issue. I have a late 2009 MBP unibody. When I purchased this it was the highest 15 in model you could buy. I've already had the Motherboard ( I forget what apple calls it) replaced while still under apple care because the usb and network ports stopped working. Hard drive has been replaced due to crash while under warrenty. Now I am out of apple care and the issue is still not resolved.

I have been reading here and I did not see any mention of other probs I am having. My MBP powers down automatically very frequently after being awaken from sleep mode. It also goes to gray screen telling me I have to hard restart. And it runs very slowly almost always. I have just ordered upgraded ram to see if this will help but I am lost if this does not help. I spent almost $3000 on a mac that has only lasted me 3 yrs. Not a great return on investment. Any suggestions would be appreciated. Thanks


I also forgot to mention Genius bar has no idea what to do. They run test and it all shows ok so they say I must be wrong. Great customer service.

I have a MBP 2011 i7 2 2 years now i have working with it. I have experience heat issues since then but never when i first bought it, based on the heating problems i had in, i think the mayor issue is with the fans, and air flow inside the MBP, its not overheating is just getting dusty and the fans not able to dismiss the heat genereted by the CPU- please not here that a processor that powerfull is not something alot people can undestand. Anyways all i have to say is very straight forward.. All you have to do in order to avoid heating problems on your MBP is 2 mayor thinks :1st dont use programs to monitor the behavior of your system and 2nd when your MBP gets hot just close it and leave it for 10-15 min.
For me at list this works fine.
