IMac getting hot!

Is this normal after 1 hour only surfing the web:

I disagree; I'd say you're on the hot side. Nothing that's imminently dangerous, but, long term, temps like that will kill hardware. However, with an ambient of 31C, that might be somewhat expected. smcFan Control can help bring those temps down. When necessary, I also run a small clip-on fan attached to a bracket on the wall behind the computer. The entire back acts as a kind of heat sink, so cooling that down will help keep the internal temps lower. Take a look at my posts in this thread for using smcFan and a snapshot of my temps.

Ideally, you want to keep the HD temp lower than 45C, although this may not always be possible. 53 is a bit too hot for my taste. I really don't like going above 49-50C. Your power supply is running very hot.

Why is it that I have to install a third party software to control my fan speeds when my iMac gets hot. Should't the system manage this. My iMac is over heating because of this. Is there a way to let me iMac manage the fans?

I've read many posts talking about using a third party software to manage the fans in my iMac. Can the iMac not do this on its own?

You don't have to do anything. The fans will run when the temperature gets hot enough to trigger them.
My new 2012 iMac isn't like my older 2007 iMac in terms of fan noise. I knew when the 2007 fans were running, I could hear the sound of rushing air and under heavy load they were load. Because the new 2012 models are very different in construction I don't hear that typical sound. In fact, until I saw a teardown I wondered if it had fans. The fan sounds more like a hum and I just never associated it with being a fan. Yes, the top of the computer does get hot, I think part of Apple's design is to use the alumnium back as a heat sink.

Imac gets hot while gaming

My relatively new imac gets very hot and the fan comes on while gaming. I usually don't play the games but my grandchildren do and I would like to know if this use can damage my computer and what if anything I can do to protect the computer and still allow gaming. Thanks, your input will be most appreciated.

Thanks Dave. I did notice that once the fan came on and I shut down the game, the computer cooled down and stayed cool. The fan ran continously until I shut the iMac down including while I was gaming (well over an hour). It occurs to me that perhaps the fan should kick in sooner? Is there an add on that would be helpful or perhaps a small fan aimed at the computer?
In searching the web I ran across something called "smcFanControl2.2.2." ... your thoughts please. As you may have guessed, I am in way over my head here. Again, thank you.

Is it Ok that newly purchased iMac gets Hot not just Warm, and smells sometimes like burnt plastic?? Just by using safari for mails And playing Radio??? Or i must throw it!! since Can't get any Direct contact to Apple!!!

IS IT OK that a newly purchased iMac -intel Lion- gets So HOT That it smells like Burnt Plastic,Not Warm but Hot!!??.. Just only by using safari-reading mails or newspapers- And playing Radio with VLC??!!!!...Or i must throw it away before it explodes??!!...Since Not possible to contact direct Apple to replace it !!!!..-they send me automatically from one adress to the other And No reply!!.THANKS!!

I don't know where you live or what you're talking about being sent from one address to another. Your iMac has a 90 day warranty with tech support and service, if needed. Apple has toll-free phone numbers in the US. You call that number, get to speak to a tech, give that person your computer's serial number and describe the problem. I suspect that there are similar arrangements in other parts of the world. That is "direct contact" with Apple. Have you tried to do that where you live? Wny are you trying to communicate in writing (by e-mail?)? In addition, if you don't have Apple Care you should immediately purchase it if you're still eligible. It'll extend your warranty to 3 full years.

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.

When i play dirt2 my iMac gets super hot to where the top will burn my hand is that normal

is this normal

When your computer gets to hot it will shut down. Your numbers after playing a game for 30 minutes are about right and isn't putting to much strain on your computer.
In the summer months I have seen my iMac get above 180. If I'm compress a HD video and using all of my cores my fans kick in at over 2000 rpms.
The above image the iMac is not really doing anything... nothing to worry about. I've never had my iMac shut down from being to hot.

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!

Why is the new iMac so hot to the touch????

Was just at Best Buy checking out the new 27" iMac pentium i5's. Why are they so darn hot to the touch? Is this normal? How can that be a good thing?
I need to know because this is the only thing preventing me from purchasing one.
Thanks.

Hi.
If the heat you notice on one machine at Best Buy is the "only" thing preventing you from purchasing, then my best suggestion to you is to let it go.
You know that every computer produces heat. Some dissipate it better than others... some just differently.
Some create more heat than others because the processors demand more energy to perform their intensive tasks properly. The 27" iMac is such a machine. Not only is it required to do all the things any other iMac might do, it's designed to do it faster AND to while driving a big, beautiful 27" display. Any processor that can do that is gonna get hot.
Relax. If you like the machine and what it offers, and if you can afford it, buy it. You know Apple will stand behind it for a year... and if you want the added comfort of 2 extra years of support, you can drop the $ for AppleCare.
Are you happy with the iMac you have? The new one was designed by the same great team of engineers.

27" iMac running hot, loud fans, restart each day

I have a current model 27" iMac 3,4GHz Intel Core i7 with 16GB Ram, Dual Drive (250 GB SSD, 1 TB SATA) with a second Thunderbolt Display. Each day I run Safari, Mail and Chat along with itunes (Music) or Pandora, and 1 possibly one or two other programs (Photoshop etc) but nothing overly taxing. Without fail, the fans start running and within 30 - 45 minutes the computer starts running slow and freezes up. This happens once a day between 1 and 4 PM.
The temperatures are climing into the 170 range. (I would put more specifics but it is actually starting to freeze up as I type this and I dont want to start over.
Any assistance would be greatly appreciated.

UNINSTALL FLASH PLAYER AND USE CHROME!!
I've had this problem for the past 3 weeks. I've taken it into the apple store and an apple certified technician.
I've done SMC reset and all the things you will find when you research this issue, besides opening up your computer.
I noticed the CPU fan would go crazy 30-40min into using safari. I would put it to sleep, wake it up, it would stop but then start back up in 30min. When I took it into apple, the technician said that flash uses up a lot of processing power, tricking your computer into thinking it's getting hot. (don't quote me on the "tricking" part, that's just how I sum it up.) He said for web browising he uses chrome because it has a built in flash.
My computer was running fine otherwise, apple even said so. The CPU fan was just going crazy.
I uninstalled my flash player, restarted the computer, I now use chrome, and it hasn't happened since.
Not saying that this will solve everybodys problem, just saying this is what worked for me.

Why is my 27" IMac so hot on the upper area of the monitor?

Why is my 27-inch desktop iMac 10.6.8 OS Snow Leopard OS running so hot while in use?
My Hardware Overview:
Model Name: 27-inch Desktop iMac, Model Identifier: iMac11,3
Processor Name: Intel Core i3, Processor Speed: 3.2 GHzNumber Of Processors: 1
Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB
Memory: 4 GB Processor Interconnect Speed: 5.86

How hot is hot? For example is it that hot you can fry an egg or it literally burns your skin? If it's neither of those it's safe to assume the temperature you're sensing is actually warm rather than hot. The area you're referring to is where the hard drive is positioned. This can and sometimes does get warm in normal operation.
If it truly was getting hot to the point where you're in danger of burning your fingers the Mac would switch itself off which is not something you're describing.

IMac running hot (21.5-inch, Mid 2011)

Hi
I just wanted to give a heads up on my new intel iMac running hot when the monitor is brighter than half way or (newer) games are set to high graphics performance.
I was concerned from the back of the computer feeling very hot so I popped off the front glass and LED screen and took a couple pictures of the logic board where I assume capacitors or on the other side:
You can clearly see where the logic board is getting hot with a little scoring.
to resesolve this issue, I simpy run my games (which are newer ones btw) at lower graphics settings and keep the monitor level below half way. . .
anyway, just thought you should know.

Ok panic over
I found this http://www.derman.com/iMac-Fan-Control
I set the minimum fan speed to 2000, machine is much cooler now. I suppose so long as the fan does not wear out I'll be fine now.
You know picures like you have taken are very worring, iMac is VERY expensive and I expect quality and I don't expect to see what you have. I feel your pain bro...

Why is my imac getting overheated?

My Imacs one week old and it gets overheated really quickly. Is there any way to stop it overheating quickly?

Don't worry.
The case of the new iMac is made of aluminium. Aluminium not only looks "cool", but actually keeps your iMac cool. It is a very good conductor of heat.
So it transmits the heat from the inside, where if it built up, it could cause harm, to the outside, where it is dissipated into your room. So long as your room is not uncomfortably hot, then everything is working fine.
If that part of your iMac feels hot, then the aluminium is doing its job.
Don't bother shutting your iMac down unless you are going away for many days. Just put it to sleep if you like. But be aware that OS X does some maintenance tasks late at night, so it's not good to sleep it every night.
Hope this helps

IPhone gets hot on long-ish calls

Talked to my sister yesterday - about an hour - using the iPhone. Call quality fine, but the back of the device got seriously warm, not burn warm, but definitely uncomfortable warm. A) has anyone else run into this? B)this makes me a little wary of buying a cover, as I don't want to overheat it.

The phone also gets hot while surfing the web and while charging too.
I bought one of the silicone back covers for the phone and made the mistake of leaving it on while using the phone for calls, surfing the web, viewing images, listening to songs and charging the phone the whole first day I got it. My iPhone worked fine at first, then all sorts of weirdness broke out.
Now calls almost never have sound coming from the earpiece, WiFi is unreliable, enabling bluetooth freezes the phone in its tracks, screen re-draws and menu navigation freeze when entering or exiting Settings.
We live and learn.
I took the silicone cover out to the workshop and drilled 87 holes in a grid pattern across the whole bottom of it. Hopefully this will help dissipate some of the heat. I'll use the cover if I'm going somewhere, but not if I'm using the phone or it is charging. A phone repair is in the works.
All the best

Back of iMac extremely hot, temp check anyone?

Hey everyone,
I bought my iMac in Sept. of 2011. Specs are:
2.5 GHz i5
4 GB ram
Mac OS X 10.6.8
and other specs as well...
I don't use my DVD drive a lot, but when I do, it's normally when I play The Sims 3. I've noticed the back gets EXTREMELY hot, and lately my game keeps shutting down for reasons I cannot figure out. If any of you know about The Sims, I've already gone through almost every troubleshooting solution I can think of, so all I'm coming up with is that my Mac is overheating.
I downloaded the iStatPro deal to monitor my temps and they are as follows:
HD: Macintosh- 53
CPU- 45
Ambient- 31
GPU Diode- 65
GPU Heatsink- 63
Mem Controller- 60
Optical Drive- 48
Power supply 2- 54
(these are the current reads about 30 min. after the game crashed, so essentially the DVD drive hasn't been used in 30 min.)
I think these are all higher than "normal" (from what I've seen on a few other posts). Is my mac in danger of overheating? I really don't want to damage this, it's just over a year old and I can't afford to go buy a new one or even get this fixed. Any comments or advice is appreciated! Thank you so much!

Welcome to the Apple Support Communities
Your iMac works properly. Those temperatures are normal for the iMac, and games need full performance, so that's why your iMac is hot. Also, your iMac has got fans in the back
