Mbp running too hot too often.

hi there,
my mbp 2.5 has been fine for the first 4 months or so, but lately its been running fairly hot (between 60 - 70C) when all i have running is itunes and firefox. The fans spin up to 3000 rpm, and are pretty loud compared to how it used to be.
i have fan control installed, not sure if that effects anything.
any help would be much appreciated.

Hi tt: I would say that is your problem process. Any process using 99.3% of the CPU for extended periods will cause issues. It looks like you are using iAnti Virus, Yes? What happens if you highlight the process, then click "Quit Process"? I see there are some issues mentioned about this program in other forums. I don't use the program so I can't speak to how well it works.

Photos makes MBP run really hot since update 10.10.3 (14D131)

Hi
I updated to 10.10.3 (14D131) and each time I access the new Photos app my MBP now gets really hot, the fan runs constantly until the program is closed.
Any clues how to stop this or is it a wait for the next update to solve this?
Thanks

Thanks for the attention mate.
It's clearly related to the update. And checking the support article +*About the Mac OS X 10.5.6 Update*+ http://support.apple.com/kb/HT3194 , it says there:
AirPort
+Improves the reliability of AirPort connections, including improvements when roaming in large wireless networks with an Intel-based Mac.+
_Time Machine_
+Fixes issues that could cause Time Machine to state the backup volume could not be found.+
+Improves Time Machine reliability with Time Capsule.+
So the two things I have were supposedly fixed by Apple. I'm still waiting for a solution before I go back to my backed up state.

17" MBP running extra hot

First off; I did search, and I found http://discussions.apple.com/thread.jspa?threadID=1503027 however the issue appears un-resolved and I am unable to post in the thread due to it being archived.
Essentially even though my processor is 97+% Idle I'm still seeing temps in the 150F range both for the CPU and the Memory controller.
I do have SMC fan controller, it is able to cool me down to 135F~140F running at 5000 rpm Left + right.
Also have Istat-pro to monitor temps + processes.
This is a fairly new issue with this machine, I was satisfied before running the fan at 2500~3000 rpm while surfing with it on my lap.
Any ideas/ suggestions/ fives are HIGHLY appreciated.
FYI I'm out of my 2 year apple care
Screen shots availiable if wanted

Just repaired Disk permissions, I had several issues (see below, but still running hot)

Also here's a grab of Istat

MBP runs very hot, fans nowhere to be found.

I'm running windows on my 17-inch unibody macbook pro via bootcamp.
Currently, the only programs I have running are chrome and speedFan. Speedfan tells me my GPU is around 80 Celsius and both cores are around 65 Celsius. When I launch a game, the temperatures all exceed boiling and soon after the computer shuts down.
Google searching tells me that getting the fans to run was a real problem a few months ago but I haven't seen much discussion on the topic lately. Anybody know anything?

Apple has decreed that a NOISELESS MacBook/Pro with a long battery capacity is for more preferable than any overheating issues. Especially when running Windows and games. So it is our fault for running THAT OS and for wanting to play games. What is completely ignored is that if we want to play games with the wall adapter plugged in, there is still no attempt by the fans to correct rising temperatures.
I tried Speedfan — all it did was scare me. It did nothing for speed control, it only reported CPU temperature.
What I found VERY helpful was elevating the MacBook Pro off the desk and setting up a fan to provide a strong continuous blast of cool air under the aluminium case.
Probably long overdue is a Boot Camp driver providing effective temperature control for us gamers.

What would one have to do to have it run too hot?

I saw this advisory from Apple:
http://support.apple.com/kb/HT2101
What do I have to do to have it run toon hot and have this message appear? I live in Phoenix, in the desert, so this is a huge concern to me. Also, what happens to the phone once this happens? Is it like water damage where it is not supported by Apple and voids my extended warranty? Thanks for any input.

Copied from the link you provided:
+Some conditions and activities that may activate the Temperature warning message:+
+Leaving the device in a car on a hot day.+
+Leaving it in direct sunlight for extended amounts of time.+
+Using certain applications in hot conditions or direct sunlight for long periods of time, such as GPS tracking in a car on a sunny day or listening to music while in direct sunlight.+
This does not void the warranty, but if this occurs often, you should do something different to prevent it from occurring. I haven't received the message, but my iPhone has stopped charging due to the internal temperature being too warm at the time.

15" MBP too hot to handle, gpu artifacting in 3d apps

Just got a 15 inch / 2.16Ghz mbp the other day. Machine runs most programs just fine, but the cpu is idling at 57-60 degrees celcius, and peaking at close to 80C under any kind of load. The chassis (bottom and top rear of computer) becomes too hot to handle (yes, it burns, common problem with these machines, as I have recently discovered), and when I go to play games, I get absolutely massive artifacting.
I even tried (when playing games under windows XP) underclocking the GPU... even more than apple did at the factory. It won't even run properly at 200Mhz core / 180mhz vram. (Normal speed for the x1600 gpu is 470Mhz on the core, apple has it set at just over 300mhz by default, the thing generates too much heat for the cooling system and generates massive artifacts in games even at 200mhz...)
Being a system builder and overclocker in the PC world, I have seen these problems before... but usually only after increasing gpu speeds well past their factory defaults, not slowing them down.
Given that the machine gets too hot to touch under load under both Mac OS X and Windows, and I cant play any games, I am . <-- that close to sending the machine back to apple and getting it replaced (Heard several stories of people recieving Macbooks which overheated, and getting replacements that ran perfectly fine), but before I do, I was wondering if anyone here knew of any solutions to the heat problem OTHER than...
a) the SMC firmware update (its already installed)
b) the thermal paste change (don't want to void warrantee, so opening the machine is out)
Seems silly to cripple a machine like this- if the fans just ran at a reasonable speed, it would be plenty-cool, but they just dont seem to turn on enough. I understand that there's a tradeoff between the thin/lightness of a package and speed, and was ready to accept a warmer-than-your-average-notebook chassis and slightly underclocked gpu, but having the thing burn me and prove to be incapable of rendering 3d content strikes me as being slightly unacceptable.
Anyway, any solutions that don't involve RMA'ing my new machine or voiding the warrantee would be most welcome. Thanks.

Just for the sake of satisfying my curiosity, I tried reinstalling the Apple-supplied GPU drivers.
Still no-go. Here's what planetside (a 3-4 year old game, by the way, nothing super demanding...) looks like after about one minute of gameplay!
[img]http://img144.imageshack.us/img144/9518/artifacts002fo6.jpg[/img]
Notice the... well, lack of WALLS where WALLS should be, et cetera. Absolutely massive artifacting. Thats under XPsp2 w/ apples drivers. Same thing happens using Omega drivers for the GPU.
Im going to run some loops of 3Dmark now just to document the issue a little better. Oh, and in other news, when Planetside is launching there is loud fan noise and airflow, but once I launch the game and start playing, the fans seem to turn off. Since the fan voltages should vary based on temperatures as measured by various sensors on the machine (usually a diode built into the CPU, plus whatever other sensors apple chose to install), it seems illogical that the fans should run when I go to load the game, or sit at the main menu, and then turn off again once I start playing. Temperatures should either remain the same in-game as at the menu or increase during gamplay due to increased CPU load.
Anyway... yes. If it continues to artifact in a benchmarking program like 3dmark, I guess I'll have to send the machine back. Is it true that they (apple) actually take your machine, take it apart, replace the logic board, and send your machine back to you? If so, I wouldn't have to worry about the harddrive I guess. Would be nice not to have to spend a day installing software and copying media again.
As for the purpose of the macbook... I really dont intend on using it as a "gaming machine" since I already have a desktop for that (which has a 2Ghz dual-core Opteron cpu installed which idles at 3-4 degrees C above ambient air temps on plain air-cooling I might add... and it's very quiet). I really wanted a laptop that was smallish, lightish, game-able laptop without sacrificing things like a decent CPU or optical drives, and well designed functionally. The MBP seemed to deliver in all these categories, and if the GPU would run properly at its stock speed, it would be the perfect machine for me. Quick enough to handle modern games like BF2 and Oblivion on "medium" graphics settings with playable framerates, small, thin, light, and able to boot OSX when I am not gaming (I do love OSX-- its like linux, but hastle free!)
Anyway. Yes. Time to request send-backage I guess. Anyone know where I can do that? (This "support" site seems to be designed as the ultimate decoy to protect apple's tech-support email addresses and phone numbers... lots of "did you try restarting your computer?" and "Are you sure your computer is on?" and "but its supposed to burn you a little" and such, but I can't manage to track down an RMA request phone number or email address. Maybe I should look through my box and stuff. Perhaps on the invoice or something. *shuffles off to dig through paperwork and miscellanious web pages*
Thanks

How "hot" is too hot for new MBP?

What would you consider too hot for my new 2.8Ghtz MBP?
Istat shows temps around 150-165f with fans running 2001rpm most of the time.
It feels very warm to the touch underneath.
Thanks

something is wrong with the new MBPs cooling system!

My PB runbs always too hot: it burn my lap. & battery runs only 1 hour.

Hi.
As the subject, my PB runs too hot.
I found sombody asked the same question and downloaded software to measure temprature.
Battery: 35 C
Power Supply Bottomside: 55.8
Processor Bottomside: 62.5
Processor/Controller Bottomside: 64
SmartDisk Fujitsu .... 48
Trackpad: 40
I'm not running any games. don't know why so hot.
And my battery last shorter than before: I was surprised it lasted only 1 hour or so last time I used without AC.
Anybody any suggestion?

Hi Shiho,
It sounds like your Powerbook is stuck in turbo mode Have a look at the energy saver tab in System Preferences. Make sure that the performance settings are set to automatic. This will make sure that your processor scales to your performance needs and isn't at 100% the entire time. Doing so would cause it to heat up significantly and as a result drain the battery much faster.
Additionally, make sure that there is sufficient air flow at the bottom of the powerbook. If necessary, prop the back up by placing a book under it, or have a look at purchasing a Grffin iCurve or iLap to elevate the laptop. The other temperatures you posted are normal and within spec, and the processor temps look normal for one which is under a bit of a load.
Good luck!

Is it normal that my macbook pro cpu runs too hot?

I downloaded the smcfan control since my laptop was running too hot and I only bought it 3 days ago.
It says that my temperature goes up to 90c sometimes and it is too hot to even touch!!
I am a bit worried, I adjusted the fan settigs to higher rpm and it seems to help a lot, but why is it so the fans are not automatically adjusting when the temperature is so high? Is there something wrong with my laptop - I could still get it replaced with a new one since I just bought it..
My specs are:
MacBook pro 15" 2011
i7 proccessor
4GB or ram
Thanks in advance!

194º F / 90c is the typical temperature if your doing a lot of heavy CPU load.
Check your Activity Monitor in your Utilities for any runaway processes.
If you first boot your machine and it gets these sort of tempertures with nothing else running, you very well indeed have a problem.
The average temperture using smcFanControl with default Apple fan speeds should be about 120º F cold boot, at idle/light load (just a simple browser window no video) CPU in a 78º F enviroment.
Iv'e bumped my minimum fan speed to 4000 RPM, and thus my smc reported temperture is about 100ºF for those same conditions.
If you way above these typical conditions (others report about the same) then yes I would uninstall smcFanControl and then take the machine in for a evaluation, you could have a dead fan or sensor, etc.

[Solved] No grub installed. Now laptop running a little too hot.

I had fedora and crunchbang already running on my laptop so I had't installed grub. Now my laptop is running little hot even after installing Laptop Mode Tools
and there is no grub in /etc or /etc/default where I can change any values. If I install now and update after changes, will it affect my existing crunchbang grub?

derhamster At first I'd thought MatLab is the culprit. But then even with only leafpad running, the laptop was too hot.

GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.lvds_downclock=1 i915.i915_enable_fbc=1 i915.i915_enable_rc6=1"
made things a lot quieter. Hence I had asked.
DSpider and cfr You confuse me! I have intel graphics only. Don't have a dedicated graphics card.

IMac (late 2013) running too hot

Hello there
A colleague has one of the newer 27" iMacs with Haswell (i7 3,4GHz) and the CPU seems to be running way too hot.
When rendering the fans start to kick in (which I never heard before on the previous generation) and the CPU temp goes to 100Celsius.
When I'm rendering on the previous gen I'm getting temperatures around 80 Celsius and the fan never kicks in.
Any of you guys with the newer iMacs (late 2013) care to post some temperatures for the CPU?

Any of you guys have any experience with the newer models?
I would really like to learn what kind of numbers other late 2013 iMac users are getting.
The number definitely is high but I wonder if the next model that will come back will be the same.

660ti running way too hot.

I recently ordered a MSI N660 Ti PE 2GD5/OC GeForce GTX 660 Ti 2GB for a new computer I built. I downloaded a couple of temperature monitor programs and noticed that the GPU temp was getting as high as 80-85c under full load. Idle it's around 32c. This seems like it's way too hot. Even though it's brand new I used a can of compressed air to try to clean out any dust, which didn't help.
Any help would be appreciated, I'd really like to get back to playing games without fear of melting my GPU.

That is not way too hot as it's max temp specified for is 97°C: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-660ti/specifications
Also only use Afterburner to monitor temps of your PE (best with OSD): >How to use MSI Afterburner<
Check with running Kombustor out of Afterburner and if card does not exceed 90°C you are fine with any game.

When battery charging ,the left of MBP is very too hot to suffer

when charging the battery of macbook pro(101)that was bought in 2012, the left part of the computer is too hot to suffer，which is near the range of the connector between the computer and the recharge. is it normal? what I worry about is that the component of computer working under high temperature will be less life.

It will not harm the computer, That is where the dc board is, it can get very hot sometimes, especially since the majority of the heat producing components are near the upper right corner too. If its very very hot, I mean like enough to burn you then maybe there is a problem.

A305-S6845 Running Way Too Hot and Shutting Down

Greetings! Has anyone else had a problem with a Toshiba Satellite running so hot that it shuts down all by itself at least once per day? That is what mine is doing. The fan seems to be running fine and there is no dust or anything like that in the way.
How can I cool this thing down? Around 60 minutes after startup, it is so hot that it is uncomfortable on my palms to use it. It will normally run super hot like that for several hours and then shut down automatically, presumably to keep itself from melting or something.
Thanks in advance!

Could be hair and lint in the processor heatsink or perhaps the thermal compound between the heatsink and processor has dried out.
Have it serviced by a competent shop. If you are feeling brave, DIY following the instructions here:

My macbook pro 13" 2010 runs hot . How hot is too hot?

How hot should my macbook pro run? How can I tell? It's quite warm on my legs and the fan turns on soon.

They do run quit hot, however should not be so hot that it would burn you. If you feel your computer is running to hot, take it into your local apple store. They can check the running temperture of your computer, and will tell you if it is outside of the norm.

Mbp running too hot too often.
