More mbp heat issues.

hi,
I recently (about a week or two ago) got a 15" mbp 2.4 Intel version and it seems to run a bit hot. weather this is something to worry about or just paranoia I don't know. I installed istat pro and fan control and when im running off the battery the temp seems to run around 30/40 celsius with the fans ranging from around 2000/2200 rpm. When its running off the power cable it seems to get hotter right now with safari open and streaming a video my cpu is at 57 and my fans around 3000. The hottest is the gpu dioed that is at 66. Also where the lead is plugged in its gets a bit hot around that area. Basically what i would like to know is if this is normal or should i get it looked at?
thanks

All perfectly normal, although I'm surprised the fans are running so fast; my CPU is currently running at 68° and GPU at 57° and the fans are idling at 1000rpm. The left hand side of the machine will get hotter than the right, and the hottest point of the case will normally be near the screen hinge just above the F1/F2/F3 keys.

How I got my MBP heat issue resolved...

Like many MBP users, I too was having heat related issues. I decided to change a few things to see if they actually worked.
1. When I don't need the full power of the processors, I change my power source in the battery menu to "Better Energy Savings".
2. I don't run as many dashboard apps and when I find one, I make sure it is an Intel native binary.
3. I updated the SMC firmware on my Mac.
All three of these chanages have dramatically changed how my MacBook Pro works. I can now place it on my lap without any issue whatsoever.
I hope this works for you too.

Thats a great idea,
why do purchased the MPB, if you reduce the power rating?
Under this conditions the MPB is now slower as the good old one.

More MBP Display Issues

OK. SO I know this subject has been posted on a number of times but I can't seem to find any definitive answer so apologies in advance for bringing it up again. I have had my 15" MBP for almost 20months and all was well until today when it decided not to display anything. The problem seemed to happen after a sleep when it wouldn't come out of sleep mode.
However, I can boot the machine up and even though there is no display, the machine is active - I've connected to it via Desktop Sharing. I've attempted a Firmware recovery but I'm not convinced this is working since I follow the instructions but the machine simply boots in to OS X almost immediately.
I have tried an external monitor but to no avail. I have also tried following some instructions that suggested deleting the old sleep file but again, no success.
One odd thing is that when I run up the system profiler via screen sharing I see the graphics adapter as GMA X3100. This is odd since surely this should say NVIDIA xyz? My MBP is a 3,1 model from early 2008. 2.4Ghz with 4GB DRAM running the latest patches.
Could this be the NVIDIA card issue that Apple have posted on their front page?
Any other troubleshooting tips?
Many Thanks!

Have any heat issues been fixed in the new MBPs

I'm interseted in buying a new MBP. Does anyone know if any of the heat issues been fixed in the latest MBPs? And are the GPU's still underclocked?

Nicolas, I've got a week 12 MBP and have never considered it to have a heat problem.
Just made another 15 minute run of System Load with both CPUs at 100%. The CPU temp momentarily hit 78 C, then the fans kicked in (quietly) and the temperature stabilized at 73 C.
The current CPU temperature is 51 C, which is normal for routine writing, Web browsing and downloading to my database. When I'm doing database work that frequently but for only brief bursts pegs the CPUs, the temps run in the high 50s to low 60s C. On battery power, the temps drop several degrees C.
The computer remains comfortable to use at all times. Note: I use it on an aluminum tilt stand, whether on my desk or in my lap.
Haven't done the "grease fix" and don't plan to.

Anyone have heat issues on 2011 MBP, WITHOUT the CPU being used at 100% ?

I hear many people having heat issues with the 2011 MacBook pro. All have mentioned some process using 100% of CPU. I wonder if anyone has heat problems even though the CPU is not being used at 100%. This would shed some light as to whether the problem is related to software or hardware.

Mine too. Get a inferno hot, and i cant use Firefox anymore, because the fans stars in less than one minute.
Everything started after the instalation of the OS X LION.

Macbook Pro 13-inch, mid 2009. Heat Issues

Hi!
What can i do?
I have a macbook pro 13" from 2009.
The fans are always on 1999 RPM, they never go faster, not even when the computer reaches a temperature of 80° Celcius.
As soon as I go to youtube to watch a video, the temperature goes up alot, but the fans stays at 1999 RPM and they refuse to go up. So the computer just gets warmer and warmer.
So I downloaded a program called smcFanControl, and when i watch usually any video on youtube, the temperature goes up to around 64° Celcius with the fans running at around 3500 RPM.
I can forget about watching ANY HD 720p video on youtube, because then the computers temperature reaches at least 70° Celcius even with the fans running at 4000RPM.
I am SO sick of this heat issue.
What can i do?
The room I am in, isnt even warm. My sisters Sony Vaio is at 40° Celcius when watching the same HD 720p video.
And this problem doesnt only occur when I watch HD videos, i get it no matter what video I watch on youtube. Highly annoying.
Why cant my macbook pro control the fans automaticly? Is there any program that i can use so it controls the fans automaticly? Because I am SO tired of controlling the fans all the time, i need to control them when I go to youtube, when i go to expressen.se (Swedish news online), I need to control them when using videocall via skype, yeah almost all the time!
Does anyone have the same problem? Or any idea what to do? It doesnt even matter if I'm downstairs in the livingroom where its really cold, I cant watch videos on youtube without the temperature reaching sickingly 80°celcius, or 64°Celcius with the fan running faster, which I have to do manually by the way.
I would just love for my macbook to control them automaticly, I hate that i have to do it.
Please help.
I run Mac Os X 10.6.3 (Snow leopard), I have a 2,26 Ghz Macbook Pro 13 inch from mid 2009.
SMC-version 1.47f2
Please help,
Kind regards

Hi again PatrikK,
The temperature that SMCFanControl reports itself is the CPU A temperature diode one from what I can see. As a test I ran SMCFanControl alongside Marcel Bresink's excellent shareware program "Hardware Monitor" , which provides much more detailed information about temperatures , speeds, power demand, etc etc, than SMC is able to do, to test this and the CPU A temp diode was certainly the closest to the Hardware Monitor readings. On the video pages of the Swedish newspaper site it was generally about 10ºC hotter than the CPU core temperatures, which were generally in the 60'sC, while the CPU A diode was in the 70'sC.
So, with your CPU Diode temp at 80ºC the CPU core temps were probably only at about 70C, which, as I said, is about where the fan speeds actually usually start to increase under normal MacOSX control. (The algorithms used to determine fan speed in Macs aren't actually based on CPU temperature alone, but depend on the readings from various temperature sensors, together with measurement of electrical current draw etc, so no single CPU temperature is responsible)
All in all, when I look back at your earlier post as well, I think your MBP is probably simply operating normally in the situations you mention. It certainly won't be doing it any harm (the maximum CPU core temperatures allowable for the 13" model are either 90ºC or 100ºC, depending on the actual procesor fitted, and this equates to a CPU A temperature diode - the one your software is measuring - of over 100ºC.) At 80º CPU A temperature the fans should only just be starting to increase, and you will find that they cut in quite aggressively from then on in, making sure that the core temperatures are not exceeded.
So I don't think you need to worry about this situation in terms of the computer itself, though you should certainly be able to reduce the temperatures somewhat if you follow the approaches I mentioned with respect to Flash etc in my earlier post.
If your concern is mainly comfort when using the computer, all I can suggest is that you follow Apple's own instructions about these computers being "notebooks", not "laptops", and when using it in a comparatively "high demand" situation such as watching flash videos use it on a desk, or do what I do and simply stick it on a thin plastic or wooden board when it is resting on my knees. There are all sorts of fancy "laptop cooler" devices out there that you can spend money on if you wish, with everything from powered fans to chemically based cooling processes, but I've always found that a light weight $2 plastic chopping board from Ikea does the job perfectly well in such situations!

Do latest macbook pro's still have the heat issue? (7/10/06)

wondering if the latest revisions of macbook pro still have the heat issue.. i heard the issue of the fan going off/on causing that 'whine' is gone and now the last thing holding me back from making the 'switch' is this heat dealy.

My week 12 MBP has never had heat issues. It's fast, stable and comfortable to use.
The case bottom of my 5+ year old TiBook gets hotter than the MBP. I've used a tilt stand for PowerBooks for years, both to reduce heat and because I prefer the typing angle.
People are not getting burned. Really. If I were to charge a battery at the same time I'm running processes that load up both CPUs, the metal strip behind the function keys would get quite warm. It might be uncomfortable to touch (but doesn't have to be touched to use the computer). But it will not result in a physical burn, unless one loves discomfort enough to keep touching it for a protracted period. Even then, not a serious burn. A cup of coffee or tea is far more dangerous than a MacBook Pro.
I've encountered several hot-running MBPs owned by people that I know in my local area. In each case, the problem was caused by software that was loading up the processors at full blast. One case was a runaway process that was initiated by software that was incompatible with the Intel processors. Another was caused by a stalled startup item -- again, software incompatible with the Intel CPU. In both cases, Migration Assistant had been used and the applications had not been updated for Intel compatibility.
And still another case was a large collection of Widgets, some of which are badly written and load up the processors. Deactivating all but 3 or 4 Widgets made that computer run cool and quickly.
Complaints about heat on this forum dropped dramatically after the last firmware update.
If you want the most powerful notebook computer Apple has ever designed, get a MacBook Pro. I'm delighted with mine. No fix necessary, thank you.

Whats happening with the 2011 macbook pro heating issue?

Hi guys,
I have a 2011 mbp 15" 2.2ghz and i am wondering if the heating issue is affecting me?
I tried seeing what my max temperature was...
I played taken in hd and bourne ultamatim trailer at the same time with 2 youtube video playing while plying modern combat.. i had around 85 celcius mark
Is this normal?
Do i need to get the Thermal Paste changed? whats the deal with this?
Also I heard that apple disabled turbo boost, is that correct or false?

one of the benefits of a laptop
Laptop is a misnomer often applied to notebook computers.
have Apple say their computers should not be used on my lap
Notebook computers violate all basics of ergonomics to facilitate portability. Many users require more comfort than is achieved when using a notebook, which is why stands, external keyboards and mice are all offered by third party vendors to enhance the user experience of their notebook computer.
No human being that has reasonably good posture habits should consider using their lap as a top for a portable computer.
It makes my neck hurt just thinking about it........
I can't believe that OSHA, Workman's Comp Insurance, etc., doesn't have rules against the improper use of notebook computers.....
is supposed to be the ability to not be at a desk.
One of the benefits of these computers is portability. Whether or not that is involves a desk is up to conditions at hand.
Misuse of this portability does not negate the positve attributes that abound.
If you don't want red marks on your lap, use the machine properly....

April 2010 MacBook Pro Heat issues.

My first post and first Mac, so please be patient....
MCP 15" HiRes glossy, Intel i7, 500G 7200rpm HD, (you know the rest)
I had bought my MBP in late April, the machine is great had no issues at all outperformed any comparable machine I put it up against. After having it a couple weeks I decided to push the video card a bit to see how it handled gaming. I reopened my World of Warcraft account and noticed a great deal of heat being put off by the machine(too hot to touch above function keys). For days I read forums on both Apple and World of Warcraft to see if the heat output is normal or not.
Things unclear to me are what exactly is Apple, Nvidia, and Intel claiming to be normal operating heat levels? (Exact temps please, I monitor using istat)I am running World of Warcraft between 160 F and 170 F and occasionally in the 180's with the frame rate dummied down to 30 fps and some other settings reduced. I should not have to do that. Its used on a flat surface, no obstructions. I refuse to buy an extended warranty for a built in system killer such as heat(would rather return and pay less). Did a hardware test everything passed. Fans running normal between 2000 and 3000rpms during use. Like I said in the first sentence this is my first Mac and think this is a little too hot in my opinion, but I am no expert so if i am wrong please tell me. I love the notebook but am worried about the heat, and cannot afford to shell out another $2200 in a year or two for a notebook that over time failed from heat issues.
I am coming from an HP ZD8000 with a 256mgb ATI video card that had only gotten a little bit luke warm at maximum settings and 60 fps in World of Warcraft, but that desktop replacement had 4 fans.
Should I have Genius bar do a GPU test? or is this heat acceptable?

Nate, welcome to Apple Discussions!
In short, your temperatures are perfectly normal. In fact, they're a bit on the cool side. I assume you're reporting the CPU diode ("CPU") temperature using iStat? If so, the temps are completely and perfectly normal.
170ºF is only 76ºC. The CPU is rated up to 105ºC (221ºF). If you've got the fans speeding up at that temperature then it is running perfectly normally. You've got a lot more room there before anything ever becomes damaged. And, rest assured, if the temperatures ever climbed to a point where damage is possible (I've never heard of that and I've been on these MBP forums for 2 years) then the machine will automatically shut itself off. There is no way that you could do damage to it with heat.
Like I said in the first sentence this is my first Mac and think this is a little too hot in my opinion, but I am no expert so if i am wrong please tell me.
You're wrong. It's perfectly normal. You don't need to be worried. They're designed to run warm under heavy load. People use these things for rendering and encoding video all day long. Yours will be just fine if you play Warcraft on it once in a while. Bump up the settings a bit too; I don't see why that would generate any more or less heat.
I am coming from an HP ZD8000 with a 256mgb ATI video card that had only gotten a little bit luke warm at maximum settings and 60 fps in World of Warcraft, but that desktop replacement had 4 fans.
Well, that's the problem. That thing was plastic, correct? And probably 2" thick? With huge fan vents on the back? The MBP is exactly the opposite of that. Metal conducts heat much better, and helps to cool the computer too. However, you also feel the heat more. The MBP is half the thickness of that thing, and doesn't have the vents either or the huge fans. All it means is it will heat up a bit more, but it's been designed just fine with that heat in mind.

After several repairs, still having heating issue with MacBook Pro (mid '09)

EDIT: this post got removed the first time for not being constructive enough. I've now edited the post.
This is going to be a lengthy post, so bear with me.
2 months ago, I suddenly noticed my MacBook Pro (medio 2009, 15", 4GB RAM, GeForce 9400M) heating up a lot harder than usual. I'm familiar with the heating issues these laptops have, but this wasn't normal. Looking at iStat Pro, I saw my fans almost taking off like an airplane at 5700 rpm, while watching only a livestream on my browser. I know Shockwave Flash takes up quite a chunk of your CPU, but I had never encountered this problem beforehand.
The biggest problem wasn't just the heat or the fans, but the fact that my computer also started reacting rather slowly. Sometimes I'd even get beachballed, or the whole browser stopped responding for half a minute...
So I tried to see if gaming was still an option. Of course not. I had been playing League of Legends for several months without any issues. Whilst playing, I'd kick up my fans manually to about 4000 rpm, and they'd stay there throughout the whole game. Now, when I start up the game, it plays smoothly for the first 2 minutes. After the temperatures rise to a critical level, the fans start spinning up to 5700 rpm, and the whole game plays like a powerpoint presentation.
On a sidenote: it sort of 'lags' every 1-2 seconds, and sometimes, after a long period, the game acts somewhat normal again (20 mins). This game uses wine to run, which isn't the most optimal way. So I tried playing Team Fortress 2, too. Probably even worse results! (but again noticeable 1-2 second interval lags)
Before anyone starts screaming: "Don't use your Mac for gaming!" etc., I wish to point out that these two games had been running perfectly for the past few months/years. Something's definitely wrong.
After looking for some solutions myself, I decided to go to an authorized Apple Service in my city. A few days later, they told me my logic board was broken, and I had to pay almost 700 euros ($ 900-1000) to replace it. So I did. I got it back, but it wasn't fixed. Brought it back in. Got it back a week later: "Your new logic board we got from Apple was already broken, but we hadn't noticed. We put a new one in it. It's fixed." Again, same problem.
We're almost 2 months later and 700 euros poorer, still no result. I've brought it in about 6-7 times now, here's a list of what they've tried so far:
- In total 3 new logic boards
- New MagSafe (because they discovered it was giving too much power too my laptop)
- Fresh re-install
- Replaced RAM
- Checked fans etc. (they do this by default)
- A few tests which proved that it was repaired (but I have my doubts with these tests...)
They told me now that it's fixed, and they basically won't look into it anymore. I must contact Apple myself, if I wasn't satisfied. The tests they performed showed no signs of heating issues. (One of the tests was playing 4 1080p movies at the same time. When I watch a 1080p movie on Youtube, my laptop is taking off like a plane) They ran a stress test all night long, showing no temperatures above 98°C. I got it up to 105°C in a few minutes according to iStat Pro.
They advised me to install Mountain Lion, which would make the issues with "high-performance sites" go away. I haven't seen much improvement, though.
This whole experience has been quite frustrating, especially now that I'm gonna need my laptop for University again. Isn't there anything I can do? I've paid almost 700 euros and missed my laptop for 2 months, without any results.
I've got more information regarding the issues if needed, ask away. I'm getting desperate.
I've been browsing around the support communites, and found that a lot of people are having issues since they upgraded to OS X Lion. Could this be the case? Should I try downgrading to Snow Leopard?
I've also found a few topics on refreshing the cooling pasta on the heatsink. Would they have noticed any problems with this after replacing the Logic Board several times? Or should I check it myself? I'm not too keen on opening up my laptop myself...
Nick.

Thought of buying Parallels? Fusion?
Might want to see if this gets moved to the MacBook Pro forum.
I'd think Windows 8.1 is smart enough (what I use 90% time since the Dev Preview came out couple yrs ago it seems like) to find the driver.

This is a workaround for the MBP wireless issue

There have been many topics on the MBP wireless issues already, but I thought some people might find this workaround helpful.
Firstly, my system is a 2.2Ghz MBP, running 10.4.10, and also airport extreme update 2007-04. I am using an airport express base station. My previous Powerbook never had any wireless problems, so I really couldn't blame the basestation for the MBPs poor wireless.
Warning - The workaround requires a little bit of work in the terminal. A little bit of understanding of how networks work is assumed here as well. So it is probably not for everyone ...
What I have observed - whenever the MBP loses connection, the airport basestation IP and MAC addresses are missing from the ARP table.
- To view the ARP table, type (in a terminal window) arp -a.
So, when the MBP wireless hangs, open up the terminal and type that in.
Do a Cntrl-C if the arp command is hanging and not returning anything.
In normal situations, a list of IP addresses and MAC addresses will show up.
As others have already noted, clicking on the airport icon in the menubar, will magically bring the wireless back to life. When this happens, the ARP table also gets magically populated correctly. Coincidence? I think not!
So, the workaround is to store a PERMANENT entry in the ARP table for the airport basestation IP and MAC address. In my case, I can use the Airport Utility software to confirm what the basestation IP and MAC addresses are (note MAC address = Airport ID in Airport Utility). I found the basestation IP=10.0.1.1 and the MAC=0:11:24:07:d7:f
To create a permanent ARP table entry for my airport basestation, I opened up a terminal window, and did the following -
1) login to my administrator account
2) type in the following command sudo arp -s 10.0.1.1 0:11:24:7:d7:f
3) type in my administrator password to authorise the change
4) type in (to confirm the changes have been made) arp -a
5) logout of my administrator account (from the terminal)
Ever since I did this, my MBP wireless performance has been flawless.
Note, if you shutdown or restart your computer, the arp entry disappears. This is ok for me as I hardly ever power down my MBP. As insurance I have added an account startup item to remind me to do the arp table entry.
This workaround is great for me because I don't have a need to use multiple wireless networks. It might not be practical for people who roam around onto different networks.
Give it a go and see if it works for you.

OK, after some further experimenting, I changed the multicast rate on my airport express. It was set at 6Mbps, and I changed it to 2Mbps.
I have read that the default multicast rate for previous 802.11g versions of Airport basestations is actually 2mbps. Excellent results so far !! I have set up a terminal command to continuously ping my airport router address every 15 sec, and there have been virtually no dropped packets so far over many hours.
ping -i 15 10.0.1.1
Interestingly, in Apple's Airport Admin software in my MBP there is no option to set the rate at less than 6Mbps (!!!!), so I had to use the Windows XP version of Airport admin software to make this change using a windows machine. Using the XP software you can set the muticast rate as low as 1Mbps.
If you are using Apples airport admin software (Tiger and Leopard) and you commit any sort of change in settings, the multicast rate will be re-set at a minimum of 6Mbps. My understanding of the multicast rate is that setting it too high is similar to shrinking the coverage area of the basestation, and limiting access only to clients who can transmit at the required multicast rate.
So my new theory is that the dropouts are caused by the MBP dropping off the airport due to not being able to achieve the set multicast rate. (this could be due to factors such as low signal strength, excessive interference or noise).
If you are using Apples more recent Airport admin software, you are having a minimum 6mbps muticast rate set, and this might be too high for your particular environment.
Just a theory.
(oh yeah, I enabled interference robustness on the MBP and the basestation just for good measure)

Fixing the macbook heat issue

Hi,
There is a fairly simple solution, to at least reduce the risk of damaging your macbook by letting it run at high temps. I bought my 2.0GHz macbook over the weekend, it was idling around 70 - 75 C. Thats a little high in my book.
I put the macbook on the vantec lap2cool laptop cooler that I have for my AMD64 HP laptop. Within about 30 minutes of running, the macbook was running between 42 C (idle) and 60 C (being taxed). Now the vantec is pretty cool, but its a little bulky for the little macbook.
I picked up a targus cooler for about $24 at the local walmart, its keeping it idle around 48 C, and under normal conditions (text mate, iTunes, Firefox, Thunderbird) its running around 54 C. The targus cooler is pretty quiet, slim, but a little cheap. They sell some high-powered solutions on newegg.com with better CFM and higher RPMs.
Now I'm sure a lot of typical mac users are going to have a fit about using a laptop cooler that makes the macbook a little bulker, but its way better than the damage your going to do to the macbook by running it hot on a daily basis!!

Intel processors (at least recent ones) are well known for having heat related issues. AMD processors offer better price/performance with reduced energy consumption and output. My HP zv5000z which is AMD64 based, has two large fans on the base, and kicks off a fair amount of heat exhaust. That however is heat thats NOT in my system. If I use it for games, then I'd be crazy not to have it hooked up to the Vantec Lap2Cool.
Apple in my opinion are taking a bit of a gamble. They've had to trade-off heat issues, performance with keeping the system quiet. To me, kicking the fans in on the macbook is a last ditch attempt to keep the system from keeling over, hence the loud noise (high RPM fans). What Apple is likely gambling over is that most users will run the machines in a "cool place" and the average user won't tax the system. Your business, designer, etc types aren't going to be playing games on it. They are gambling that the system will hold up to the level of heat abuse until the warranty runs out, or you purchase AppleCare. Either way, I assume they don't lose money.
In terms of melting, I seriously doubt you'll see physical melting of the system. What you are more likely to see is heat related damage to electric components (either the processors themselves) or surrounding components, resulting in system failure (or odd issues like display problems, random crashes etc). Lets just say its in the best interest of the health of your system to keep it cool.
The fact that Apple has corrected this on the MacBook Pros with firmware / hardware changes, would suggest there is some teething issues with the move over to Intel, and perhaps a shift in the type of customers buying the macbook.
With the market being so competitive, do you really think Apple is going to say -- "Hey these Macbooks look nice, but they overheat, you need to get Apple Care because they'll fail sooner than expected, and you should buy a laptop cooler to extend the life of the product". This adds what $300.00 to the price of the laptop, thats already slightly higher than lightweight options from vendors such as Dell, HP etc. When you go to the Apple Store and the person working there insists that you should buy Apple Care because the system is going to fail sooner rather than later, that tells you something right there.
Now if a laptop cooler keeps the system running between 43 C and 60 C instead of 60 C and 90 C, then aside from your own comfort with the thing on your lap, keeping the system cool is a good idea. Unless you like to return things to the Apple store?

Heating Issues for MacBook Pro (early 2011)

Hi
Am facing heating issues and am looking for what should be the ideal fan speeds for CPU Temp range
My Mac Details
MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)
Processor : 2.8 GHz Intel Core
Memory : 16 GB 1333 MHz DDR3
Storage : 750 GB SATA Disk
Graphics : Intel HD Graphics 3000 512 MB
My standard use is Mac with one VM (Win7) running.
What I have observed is the Fan speed is generall ~ 2000 rpm for CPU temp range of 55 - 70 Deg C.
Should the fan be spinnig faster as the base of the machine does become too hot for comfort to be working on Lap.
Are there any apps that can help me run some tests to montor performance?
Please help.
Thanks
Brijesh

A MBP should not be used on your lap since your body will act as an insulator that will inhibit heat dissapation.
Heat generated will be a function of the stress placed on the CPU/GPU by the number and type of applications you have open. Skype, video, games, and the like can result in temperatures that approach and exceed 100 c. There are internal sensors that will shut down the MBP if it starts to over heat.
The temperatures that you have reported are not unusual and are well within acceptable parameters for the MBP. The fans will start to speed up, when the heat increases, as required. Some users install fan control software, but I am of the opinion that what the Apple engineers have installed is satisfactory and need not be altered.
You may encounter a runaway application as described in the following link. Usually a restart will solve the issue.

Hello Everyone. I just purchased my first MAC this past December. Its an iBookG4. It was brand new. I am having some problems though. It heats up something wicked. If I let it run for about an hour and touch the bottom its pretty hot. The longer I let it run the more it heats up. I dont think this is normal. Also it makes a pretty noticable humming sound. Does anyone got an suggestions as to what I should do or what these issues may be caused by. I am very concerned here. Thanks, Rick

Hi Enflame87,
Welcome to Apple Discussions
Your iBook will heat up, it is the nature of the G4 processor. The problem is when it becomes too hot. Does the fan turn on? You might want to download Temperature Monitor so you can see and record how hot your computer is getting. There is not much to worry about when your iBook heats up unless you notice changes in the way your computer acts. If it begins to freeze or become sluggish you might want to get it checked out at your local Apple Store/Reseller.
I like to use the iCurve to elevate my iBook off my desk (for ergonomic reasons). They do claim that the iCurve will let air flow better around your computer so that your iBook cools off. I can't say for sure that it does that, but my computer doesn't get real hot. You might want to look into a "lap desk" or something so the iBook is not sitting directly on your lap.
I hope that helps,
Jon

T61p heat issue.

Hi, tried to find a search button on here but i couldnt find one, point me to the correct thread if there is one. BUT...
My t61p burns up whenever i run any 3dprogram, the gpu shoots to ~80C. when i was on xp i could use the power manager to scale everything back and keep it under 75 but now that i am on windows7 this is not an option. It will often **bleep** off due to (what i assume is) heat issues. and wont restart til i unplug and do a battery pull. I use tpfanControl and the smart2 profile helps a little bit but not enough to be useful. I dust the laptop regularly, im all out of ideas. Ive heard that there was a fault batch of t61p's that came out, not sure if it was rumor or not.
Any help would be great, thanks.

Solved!
Go to Solution.

I had this problem before, here is what I did:
1. Disassemble the keyboard to expose the fan and memory. You need to dust off and use a blow dryer and air cleaner to blow the dust off the board and remove the fan and memory to clean everything surrounding it and more.
2. Clean the fan by blowing air cleaner (those use to clean the camera), You should get the idea that the dust around and inside the fan and on the system board is blocking air flow. Clean the memoery by remove and use a pencil eraser to clean the contacts.
3. Check your BIOS on CPU to run on automatic and balance mode. Do not force the CPU to run at full throttle at all time. Let the step technology manage it for you. I know you want to get your money worth on the CPU speed, but, the trade off is longevity of the system.
4. Maksure in the power management software configuration that you do not have CPU running at maximum performance at all time.
Good luck. BTW, I found the Windows 7 drivers and system management reduce the libility on the CPU and manage the resources well. Move to W7 will help because of it's system management.
Good luck!...
