IMac getting very hot

iMac, getting very hot at top left corner of machine if on for more than 1 hour. Smelled like something was smoldering inside.

Normally, on heat-related issues, one step would be to install iStat Pro to view what the interior component temps are. However, if you believe that something is smoldering, I would take the system into an Apple store right away.

My iMac gets very hot

Just got my new iMac which I am very happy with, but after an hour or so of use it runs very hot. The upper left and right corners are extremely hot-almost too hot to touch for longer than 15 seconds or so. Is this normal ?

Very normal. This usually occurs when doing intensive tasks. The back of the iMac acts like a large heat sink to dissipate heat. Mine gets very hot at times as well.

After installing Mountain Lion, my iMac gets VERY hot!

I installed Mountain Lion yesterday onto my mid-2010 21.5" iMac. Today, while running it normally, it got so very hot that I couldn't even touch the aluminum back. The heat could be felt through the glass on the screen.
The fans could be heard, but didn't seem to be going overtly fast. CPU, memory, and disk usage all appeared normal.
I had Firefox, mail, Excel, and 1Password open at the time; certainly the apps weren't taxing the system.
Anyone else have this problem? Any suggestions?
Thanks!

Although the specs for Mountain Lion say it will run on 2 GB of ram, you really need 4 GB to run well. You can look at Launchpad > Utilities > Activity Monitor to see the memory usage with software open. If there are a lot of page swaps, in and out, you need more memory.
Good sources are OWC and Crucial for guaranteed compatible memory.

mY IMAC GETS VERY, VERY, VERY HOT! IS IT THE CLIMATE IM IN OR MORE THAN THAT, I AM IN JAMAICA, USING IT IN A RECORDING STUDIO WITH A AC UNIT, PLEASE CAN SOME HELP.

If your Mac is running that hot, the inside and/or vents and ports maybe plugged up with dust, lint and dirt.
Are your Mac's fans always running and running fast?
To attempt to clean out some of the dust and dirt, use a vacuum cleaner with a hose and crevice tool attachment to suck, instead of blowing, the dirt out of your Mac. Power down your iMac, disconnect the power and all your connected peripheral devices, lay your iMac screen down on a soft cloth of heavy toweling and using the vacuum's crevice tool(avoid using the vacuum's brush attachments as this may cause a stic discharge issue) and lightly (to avoid scratching your iMac's finish) vacuum out the vents underneath the display. Also, unscrew the RAM compartment cover and vacuum the dust out of the RAM area. Vacuum the long upper vent the is across the back of your iMac. Vacuum out the CD/DVD slot and SD slot. Vacuum out all of the various connection ports on the of your Mac including the vent hole and grille that is visible through the iMac's support stand. Once done, re-setup and reconnect everything and power up your iMac and see if the temps go down.
If not, If you have Apple Store or other authorised Apple service or repair center, have them diagnose and, generally, check out the health of your Mac and have them clean out all of the dust, dirt and lint that maybe deep inside your Mac.
Once this issues has been corrected, to keep your Mac's heat issues down, run a small, high speed fan blowing on your Mac's back panel to attempt to keep your Mac even cooler..
Good Luck!

IMac is very hot top half of machine

I was wondering if anyone out there has a new 24" aluminum frame iMac and has noticed that the aluminum chassis gets very hot, and I do mean hot. I was wondering whether Apple intentionally went to the aluminum frame so that it would act as a heat sink. Unfortunately I'm a little concerned this heat will hurt the longevity of the electronics in this chassis.
Any comments on similar experiences would be appreciated.
Mike

on my first day of ownership) My new 24" 2.8GHz turned itself off during an Apple automatic Software Update…
I noted that (when on) there was no discernable fan noise! Oh bitter/sweet silence!
I downloaded "Temperature Monitor 4.2" and "smcFanControl 2.1.2" (both free).
With no real activity to cause heat build-up the Power Supply was at 82 C. and the CPU core 2 was at 74 C. (only 14 C. below Intel's CPU shutdown point)!
After setting smcFanControl at about halfway along the sliders tracks, sanity returned!
Temperatures are now sensible, with the Power Supply (under medium load) at 58 degrees C. and CPU core 2 at 52 C.

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:

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

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.

My iPhone 3GS will hold a full charge for only a short time, and gets very hot when not in use in my shirt pocket. Any ideas?

My 3GS iPhone will not hold full charge for very long. It gets very hot in my shirt pocket even when hot in use. Any ideas?

Double-tapping the home button does not show apps that are running. This is not a task manager, it is merely a list of recently used/accessed apps.
Basic troubleshooting of the device is reset, restart, restore. Has a reset or restore been tried?
Check to see if updates exists for the apps, this could be a simple issue of a badly coded or buggy app that needs to be updated.

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.

Battery gets very hot during use and doesn't last long, fan runs at high speed, computer won't shut down

Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off. Can someone suggest something please.
Thanks.

TS1713 my power adapter gets very hot on my mac book pro is this normal

my power adapter gets very hot to toutch on my mac book pro is this normal

Hot is normal for the charger but very hot is not. If it were mine It could be that your MBP is drawing too much current. I would take it to the Apple Store and have it checked out.

The power adapter gets very hot. Any suggestions?

The power adapter part that plugs into the computer gets very hot. I have replaced the battery and replaced the power adapter. It also has a hard time connecting and recharging the battery. Is it possible to change out the plug in part in the computer and is it expensive? Does it sound like this is what is needed to fix it? Its about 3 years old. Any suggestions would be appreciated. Thanks.

AC adapter gets very hot

I have a new Thinkpad Edge e530.
The adapter gets very hot when the battery is charging. Not so hot that I can't hold it, but still, very hot.
Relevant specs:
* Adapter: 65 W
* Battery: "the bigger one" (6 cell LI Bat-75+,62WH)
* Graphics: integrated, not discrete
With the bigger battery, am I supposed to have the bigger (90 W) adapter?
Is the amount of heating I'm experiencing (very hot, but not too hot to touch) enough to be of concern?

Hello dbuser!
Welcome to the Forums Community! How long have you experienced the A/C Adapter getting hot? Were you using a different battery before the 6 cell?
According the the e530 Personal Systems Reference the 65W Adapter is the correct adapter for the 6 cell battery. It is possible that you have a defective adapter. Does the adapter make any noise, buzzing or cracking sound? If it is making any noise there is a definete issue with the adapter you are using.

I got my 2nd iphone 5s brand you, it s getting very hot after 10 min of usage

I got my 2nd iphone 5s brand you, it s getting very hot after 10 min of usage

It means take it back to where you bought it from. If you don't want to do that you'll have to be more specific like how long you've had the phone and how you are using the phone when it gets hot. That kind of information. The more we know about the phone the easier it is to diagnose and offer suggestions.
