Macbook Pro getting really hot and loud under stress.

To put it simply, i use my macbook pro for game development. Some of the programs/games i run on it are high quality and make my macbook pro (with a 750M installed) incredibly hot. Judging from the app (iStat) the average RPM's of the fans are around 2000rpm. When i have to render something, the macbook starts to get really really hot, and the fans start getting really loud. I checked the fans RPM and it shows that they are going at 6000rpm.
The average temperature when not doing things of the CPU and other components is around 35-50 degrees celcius. When i'm working and it has to render something, and i have to play/test my creation the temperatures go up to around 90 degrees celcius.
Is this safe? I don't want the inside of my brand new laptop to melt under the stress. Keep in mind, i bought one of these because it was suggested that mac's are the better option for graphics and design rather than PC.
If you look at the picture and see that my OS is not Yosemite, that is because i've seen many bad reviews that it can cause overheating. I'm trying to prevent that as much as possible with the workload i have to work with.
Thanks for any help possible.

I just got mine a week or two ago and I also have noticed how loud and hot mine gets. Mine also has the GT 750. The heat is normal enough but how loud it gets is very annoying.
I think I know why its so loud but cant say for sure. I think its one of those fans on the gpu with side fins rather than a normal fan. Ive had graphics cards before with those fans and they are louder than the normal fans when under load. Now I go for a card that has a couple of larger "normal fans" to keep it cool. Also these side fin fans would be better for a laptop as they will shoot the hot air directly out the back.
Im still not sure why the fan spins so fast when playing a simple game. Its understandable with a more demanding game.
Hopefully you know what I mean though im not explaining it that well.

My MacBook Pro gets really hot when I open a video file of any kind and the video starts lagging and the image fades away, also with anything that starts the fan. Is extremely hot on the left upper corner. Is there something I can do about it?

My 13" MacBook pro gets really hot without extended or heavy usage

My 13" MacBook pro gets really hot without extended or heavy usage and the fan's noise is annoying, my friends say this is not normal
Is it normal?
It gets really hot especially when there is flash content

I am also having what I feel are excessive temperatures and fans while doing nothing tasks like web browsing.
Can anyone tell me what the reasonable operating ranges are for the various components?
There is a program called "Tmperature Monitor" which is free and gives even more sensor readings than iStat Pro.
Why does flash make it so hot? I have this problem too.
Also is it normal when connecting only one external display and just browsing the web for the GPU to be at 85-90C (194F)?
Any idea why iStat always shows a lower battery percentage than OSX?
Thanks

My MacBook Pro is really hot and the fan is on constantly. It didn't use to do this, does anyone know why this is happening? I have a very short battery life, so I have to keep it plugged in probably more than I should.

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

Macbook Pro gets really hot including the power adapter

Hi Guys,
Good day to you all!
I just have an inquiry about my recently purchased Macbook Pro 15-inch (non-Retina). On the first 2 days of using it by just running Mac Mail, Safari, and iTunes, it's temperature is really acceptable. However, on the 3rd day, the base of the Macbook Pro was really hot, including the Power Adapter. I even noticed that the fan was making a loud noise, just like a jet engine (just being exaggerated). But the fan activity is really unusually loud. When it got that hot, I was doing Skype with my wife, playing music in iTunes, copying photos from an external hard drive to iPhoto, and using Facebook in Safari.
What I did was I unplugged the power adapter, and let the battery reach 0% until it automatically goes to sleep. Then I will be charging it while it's off as part of the battery calibration link that I've found at the Apple support page. Also, I did the SMC reset.
I was just concerned because I don't know if I'm going to ask for a one to one exchange since it's still within the 14days return period for Apple Online Store purchase.
I hope someone can give me a suggestion and other recommendations to sort out the heat and fan issue.
Best regards,
Aris

It could if the camera wasn't properly wired and the camera was used a lot, or if the Skype software accessed the graphics chip a lot and the graphics chip was somehow damaged. A cooling pad is not a bad idea. But heating issues with Macs that present themselves with automatic shutdown are about the only one's I'd really get concerned about for the Mac. The notebook is not a laptop, and a cooling pad makes sense mostly if you are going to use it as one. Cooling it down would certainly help it regardless. If you notice a difference in performance with it, that might be worth while checking the hardware test mentioned on my tip and taking it in for. Do get AppleCare before it is a year old. That way you can bring it in and get the hardware fixed up to the third anniversary of buying the machine.

Macbook pro getting really hot

Newguy here. Not new to macs just the forum.
My question / observation is this. Since installing the thunderbolt upgrade yesterday my 13" macbook is getting really hot on the underside. It is nearly too hot to touch at times. The heat is centered on the rear corner near the power port and is there regardless of whether the ac plug is in or not.I'm concerned this may be a problem
Has anyone else noticed this?

So what I did was go into the utilities folder and open up the activity monitor application. Look for the one that's using all the cpu power then quit the offender and restart the computer.
In my case it was report crash that was doing the damage. If I simply quit report crash then went back to what I was doing it would do it again in a few minutes but quitting it then restarting solved it.
Hope that gets you going in the right direction.....

Whenever i play dota 2 my macbook pro gets really hot. is this ok?

I just recently got my macbook pro 13 inch with normal factory specs. i downloaded steam and got dota 2 which is btw a really fun game. but whenever i play it, about 10 minutes in my computer starts to get really hot on the bottom. it gets hot to the point where if i put my hand there to see how hot it is, it starts to burn and actually hurt my hand and it doesnt feel good to keep it there long lol. but im wondering if this is normal and if its ok to keep playing? When it gets that hot it makes me want to stop playing because i dont want to progressively fry the components overtime as i need to keep this computer for a long time. i almost forgot to mention that im playing on pretty settings as far as graphics. i have alot of things turned off including shadows and antialiasing and other stuff that i really dont care about and the game still looks great but the computer still gets really hot. any help would be appreciated and thank you!

Hello:
The Mac will shut down if the thermal parameter is exceeded (I don't know what that is). However, if it was me, I would stop playing the game.

MacBook Pro getting really hot when connected to a Thunderbolt display

Hi everybody,
I had this problem since I can remember, when I connect my MBP to the Thunderbolt display the laptop is getting hot and the CPU-Fan is working preatty laud.
I had to turn radio on because it is quite anoying
Here some technical data:
MacBook Pro 15-inch, Late 2011
Processor 2.2 GHz Intel Core i7
Memory 8 GB 1067 MHz DDR3
Graphics Intel HD Graphics 3000 512 MB
Serial Number C0******V7L
Software OS X 10.8.4 (12E55)
SDD: Crucial M4 CT512M4SSD2 2.5" 512GB SATA III
I don't have any haevy programs running but, I think, also the load average is a bit high. In most cases around 2.0 But when it is not connected to the display it's not getting that hot.
Any idea what the problem may be? Or maybe it's jus normal?
Regards,
Radek

I'm seeing similar behavior when I disconnect my TBD. My Retina MBP doesn't go to sleep. I get to work an hour later and it is very hot to the touch.
I'm not seeing lots of people complaining, so I wonder if it's something weird I do. Do you have VMWare Fusion or XQuartz running when you try and sleep?

When I'm streaming videos from my Macbook Air to my AppleTV, my Macbook Air gets rather hot and the fan works hard and is loud trying to keep the laptop cool. Is this harmful to the laptop? Is this normal?

My MBA fans start running when I play video too - the CPU's video processor is working pretty hard to decode the video. The fans job is to provide better airflow. The time to worry is when you play video and the fans don't run.

HT1688 MY IPHONE 3GS START TO GET REALLY HOT, AND AFTER THAT ALMOST EXPLODE...ITS BROKEN NOW.... THE BATTERY GETS FAT... WHATS THE SOLUTION NOW???

MY IPHONE 3GS START TO GET REALLY HOT, AND AFTER THAT ALMOST EXPLODE...ITS BROKEN NOW.... THE BATTERY GETS FAT... WHATS THE SOLUTION NOW???

Unfortunately it looks like your 3GS' battery has expanded so much that it cracked the whole case wide open. If you have AppleCare on your device then you're all set, just take it to your local Apple Store.
If not, then still take it to the store. Complain about the battery bursting, and make sure to tell them that it's for sure a defect (you'd think it's obvious, but sometimes you just need to drive the point in), and that it potentially could have been and still be a hazard.
Remind them that the phone has not been in any adverse conditions, extreme temperatures, or abused in any way but that you just merely used it normally. (I'm assuming that's the truth?)
If they're good about it they should replace the broken phone for you; but unfortunately there's little chance of repairing your current device.

HT1688 I am having issues get my email in one of my mail accounts so I tried to "DELETE" the whole account. But my phone will not delete a mail account. And the phone is getting really hot and battery was full 2 hours ago and now at 25%.

Well, you don't say what happens when you try to delete the account. So I don't know what else to recommend. However, if your phone is not charging, is that the mains charger or the computer USB? Also, if it not showing any change to battery percentage, then something is wrong with the software. The next step in user troubleshooting after the reset is a restore from backup. However, considering the condition of the phone right now, I would be more than willing to say your backup is going to be corrupt. But you can try. If that does not fix the device, then you restore as new, not from a backup. If the phone works, then you can try restoring the backup again, but if it messes up, you are going to have to restore as new again. If the restore as new does not work, then you need to make an appointment at the Genius Bar or Authorized Apple Service Provider to get the hardware checked.

IPhone 5 getting really hot and battery charge not lasting very long at all??

iPhone 5 getting really hot and battery charge not lasting very long at all??

Try some of these to save battery time:
Settings>Notifications>[Turn off any notifications you don't need]
Settings>General>Software Update (Make sure you're up to date)
Settings>Brightness & Wallpaper> Auto-Brightness on (And that your brightness is not to the max)
Settings>Privacy>Location Services>Turn off/Stop apps from using it
Settings>Bluetooth>Off
Settings>Mail, Contacts, Calendars>Fetch New Data>Manually
Settings>Wi-Fi> Off (When you don't need internet when you're out and about)
To stop overheating, note these:
Operating Temperatures: 0° to 35° C (32° to 95° F)
Non-Operating Temperatures: -20° to 45° C (-4° to 113° F)
Hope this helps!
