Macbook can get very hot!!!

Ok I've been having this problems every single day. Everytime I used my Macbook for about 2 hours, it gets very hot. Is it because its summer? What do I have to do to stop this?
Also, when it gets really hot, my macbook just starts freezing and the fan is going very fast that its very very hot.
Should I have my AC on or at least my fan next to my macbook?
KK any suggestions please... Thanks

Go to System Preferences - Applications - Utilities - Activity Monitor and check what app is using CPU. Try to quit this app and check the difference.
Also,what size of RAM do you have ?

My macbook pro gets very hot when running anything like games or videos

I just bought a macbook pro 2.3 GHZ i7 with retina display. It gets very hot when running just about anything of substance. When I run a game like candy crush, the temperature can get to 167 or more. I installed istat menus and started monitoring it. I did notice that the fans never went on but after istats I was able to make them come on. Without having a game going, the temperatures hover around 100. Once the game starts, it goes crazy.
I don't really know what the problem could be or if this is normal (it really can't be....This is way too hot). I have owned the computer for about 2 months and I need to know what to do.

MacBook computer gets very hot and hurts to touch

I have the last 17 inch MacBook made.
Lately my fingers have been burning and very sensitive from using the MacBook.
I thought maybe I had some nerve problems with my fingers but this doesn't happen when I use my iPhone or even an iPad, although I have not tested another MacBook.
I believe the problem gets worse when the computer is plugged in which leads me to believe that it is from the heat of the battery under the trackpad area sometimes my fingers also get heated from using the keyboard.
I have resorted to using an external keyboard and the magic mouse and I have been fine.
After almost 2 weeks of not using the computer keyboard and trackpad I went back to it and within 10 minutes I felt the heat in my fingers.
is there something wrong with my MacBook? is it overheating? I did replace the battery about a half a year ago
Or is it me?

heres is the ac info

In my macbook pro 15 inch mid 2012 model, my cpu and gpu will get very hot, when gaming or rendering sometimes over 200F. The fans only spin at max about 2900 rpm, when their max is 6400. I downloaded a fan control app, but how can i fix it?

Hi rhaughan,
I see that you have concerns about your operating temperature of your computer while using resource-heavy applications such as gaming applications. I have an article that will address some of the concerns you have mentioned:
Mac notebooks: Operating temperature - Apple Support
http://support.apple.com/en-is/HT201640
While there are third-party utilities that measure the temperature of a notebook computer, it is important to understand that these utilities are not measuring the external case temperature. The actual case temperature is much lower. Never use third-party applications to diagnose possible hardware issues—instead, contact Apple or go to an Apple Retail Store or Apple Authorized Service Provider.
You should also see this article for even further information about your fans:

thin horizontal lines appear occasionally across window of firefox, if i switch to finder, not there. appears to stay with windows of different programs.
lately above the keyboard along back edge in the middle under monitor gets very hot almost to hot to touch, uncomfortable on lap.
i have no idea what the memory cards are. some have suggested i should replace memory cards?

I don't really know about the new models as far as typical operating temperatures. The ones you mention are not meaningfully high to me. My 2011 13" MBP with an i5 CPU typically idles near 50º C.
As for the speed issue that is hard to evaluate on the basis of personal opinion. You can download and run GeekBench benchmarks and compare the results to those reported for the same model configuration. You can use CineBench to benchmark video performance.

My macbook pro retina gets very hot and slow

whenever i use my macbook pro retina for an extended amount of time 1-2 hours watching videos online or playing games it gets very hot, starts lagging and gets unresponsive, i can only use it with a fan underneath basically, my old macbook pro had a similar problem, it took like 3 weeks of them checking it to find a problem which took them another couple of weeks to fix, i cannot be without my laptop for any extended period of time. fans inside seem to be working fine, but it still get incredibly hot... please help!!!

Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity

MacBook not going to sleep and getting very hot

I just purchased a MacBook and have been using it for a few days. I have noticed that it does not appear to go to sleep correctly and gets very hot in the process. I finished working on my MB about 45 minutes ago. At the time it was connected to the mains and I disconnected to catch my next train. I shut the lid and after a few minutes the sleep indicator light at the front dimmed once then stayed on permanently. I could not hear the drive spinning (though the drive is quiet on this machine and there was a lot of background noise) and assumed all was OK. Anyhow, I have just taken the MB out of its case some 45 minutes later and it felt extremely hot (almost too hot to touch, I would guess around 50ºC). The sleep indicator light on the front was solid white. I opened the lid and the machine woke up. Something not right here....Also power remaining was down to 72% so something has been using up a lot of energy and heating up the aluminium!
Tony
ps. Whilst writing this email the MB has cooled down considerably but still warm.
ps2. Probably not related, but I have firmware password protection enabled
null

I did see some of the other posts, but nothing about the MB getting so hot.
I tried sleep from the menu and this seems to work (though I have rebooted the machine since the above report).
What worries me is the potential fire risk/damage to the MB, the case was extremely hot.

I am using a white 13inch 2009/10 macbook, purchased in the US. Am currently using it in the Philippines, where it is 220v. I know my adapter says it works from 100-240v, but is it okay to use longterm? I think my mac gets very hot now? thanks

All Apple power supplies work world-wide with the proper plug adapter.
I have my MacBook plugged into the grid all the time, 24 hours a day w/o any problems.

Macbook Pro Retina 13" Gets Very Hot

Hi, I noticed my Macbook Pro Retina 13" gets very hot after 30 minutes of usage, practically "burning" on my thigh (it left burning mark a few times actually, especially in the summer). I usually put a book between the laptop and me to prevent the heat. Is there a better way?

What are you doing on your MacBook when it gets hot? I have a retina and it gets hot when I play games like Team Fortress 2 or Garry's Mod, watching videos on youtube, and using the iTunes visualizer. What's odd is it doesn't get hot when I watch movies on iTunes. If it's getting hot just sitting around, you may have a problem that needs to be check out as soon as possible. I had a 13" mid 2012 non-retina pro that had three logic boards replaced in less than a year of purchase. Every time the board was failing, it would freeze sometime after it was put to sleep and it would get really hot and the fan would be screaming trying to keep up. Then it would freeze as I'm using it. The screen would flash pixels of all colors in random spots all around the screen. If Apple didn't cover the repairs, I would have paid $530 per repair.

My MacBook Pro with Retina display is getting very hot, is this normal?

I recently downloaded Counter-Strike Global Offensive and Minecraft on my Mac, and after about a minute of playing one of these games, my Mac would get very hot right above the keyboard. The fans get very loud and it seems a bit unusual, Is this damaging my Macbook pro?

Use it and keep it on when it gets very hot take it to your local Apple Store you might be successful and receive a new one, because the unit has to have some type of defect. Take your receipt if you still have it.

Macbook Pro Retina 15" Getting Very Hot

My macbook pro retina display 15 inch intel i7, 512gb flash hard drive 16 gb computer is getting hot. When playing a simple flash game like pocket planes (not in fullscreen), and without the battery plugged in, the computer gets to 64 degrees celsius, and the area near the battery plug location gets extremely hot to the touch. While playing youtube videos and such, the computer also gets hot, but generally reaches around 48 degrees, and it will not cool further. Is this normal? I just bought it 3 days ago and the salesperson told me that it would not get as hot as the 13 inch late 2012 macbook pro. Any ideas? Because it is very similar as heat, even though the older model was hotter.

I have the similar issue on my MBP 15" 2012. The top left corner area gets very hot after watch video for a little while.
I think it's the video card that is overheated. My current solution is to use a laptop cooler underneath my MBP. It does help reduce the lock ups in daily uses.
Does any one know how to fix it?

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?

Iv cracked my glass and only had my iphone5 for 4 days, it is also getting very hot when I call so can I still claim for a new phone if iv got a crack

For a manufacturing defect then yes.
If you drop your phone and broke the glass then no, you would have to buy an out of warranty iphone
