Imac 27" gets very hot. Is there any solution

I'm wondering if I should be concerned about the excessive temperature of my imac.

Install a utility such as Temperature Monitor 4.94 or iStat Menus 3.22 or iStat Pro 4.92.

My iMac making rattling sounds. Is there any solution?

My iMac (Intel Core 2 Duo, 2.66 GHz) started rattling noise even at the low temperature. It started suddenly and I tried SMS reset, installing fan controller etc but it does not work. It sounds like shaking a spray paint can before using. It is quite annoying and more than anything else eating out my affection for Mac. Please help me out!!

My I touch gets very hot when charging, and it won't turn on. I've tried all the resets/fixes and it does not respond. Any Ideas?

I have tried charging my itouch on the computer, in a docking station, and it gets very hot. It won't turn on, even after trying all the resets I've read on this site. Any ideas what the problem is? Is it fixable?

Hey Halefarm, What happens if you connect directly with the charging source with your cable, no docking station? Since resetting did not help, try connecting directly with the cable to your power source and your iPod. Next try a different cable, there could be a short in the one you are currently using. If still will not charge correctly, I'm leaning in the direction of a failing battery. Set up an appointment to have your iPod evaluated by Apple. Have your iPod evaluated for possible battery issues. Take the cable and dock and have them tested as well. If it is a failing battery, you choices are; replace the battery, either through Apple or third party shop. Replace it yourself, if you can. Or, you look into getting a new iPod. I don't have the cost of a new battery for an iPod 3, but I'm sure it's under $100. Check with Apple for exact pricing. Good luck, Cheers.

The case of my 7 month old mbp has started to get very hot within minutes of switching it on. Is this normal and is there anything I can do?hing

The case of my 7 month old mpb has started to get very hot within 2 or 3 minutes of switching it on. Is this normal and is there anything I can do?

The heat generated by the system is directly related to the load put on the system and the speed of the fans.
The former (high CPU load) generates heat, the latter (fan speed) dissipates it.
If your machine is getting hot then either some process is consuming lots of CPU power, causing more heat to be generated, or your fans are not working properly to dissipate whatever heat is being generated.
So the first question is whether your fans speeds kick into high gear or not? if they don't then it could indicate a hardware problem, either with broken fans, or with broken temperature sensors that control the fan speed.
If the fans do come on but the system is still getting hot then I'd look for a software issue - some process that's running rampant. It should be easy to spot with something like /Applications/Utilities/Activity Monitor. There should be a lot of processes listed, but most should use just a few percentage points of CPU power. If any process is using a lot of CPU power then it warrants some investigation - what is that process? should it be running? Is it failing in some way. Post the results of your Activity Montor report and I'm sure someone can chime in.

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.

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.

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.

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.

When I turn on my Macbook pro retina display i get a black screen and i noticed that the machine gets very hot, any clue how to make it work?

If the Mac is too hot to touch, take it in for service.

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.

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.

HT4060 When I charge my ipad on some occasions the plug gets very HOT. the ipad still charges but slower.????

When I charge my ipad using the small UPSpower adapter, the adapter gets very HOT on about every third use. It still charges but more slowly. Is any one having a similiar problem?? An sugstions as to how to correct it???

Not staff or owner by a long shot.
I just know that anecdotally I have seen people reporting issues with their mini's charging. Is there a real issue or not? I don't know. Not a day goes by that a person doesn't post here complaining that their iPad won't charge and it turns out that they're trying to do it via USB or with the iPhone block.
But while there are a lot of user fixes sometimes it's good to have the pros take a look at things,and at the very least document that there has been an issue.
the four main reasons an iPad won't charge (beyond being plugged into a USB port)
Bad cable
bad outlet
bad brick
rule those out and it leaves issue with the iPad.

Just Purchased MBA; the Charger gets VERY hot

I just purchased the Macbook Air. When I plug it in, the Charger gets very hot after a few minutes and if I listen closely, there is a faint hissing. I assume this is not normal, correct?

I plugged my late 2010 MBA 13 in recently and then after about 20 minutes, needed to move it and the charger to another outlet. I had never paid any attention to how warm this charger can get. It was so hot, I could barely hold it. I checked it a few minutes later and it wasn't any hotter, but not any cooler either. It's will be a year this month since I bought this computer so the warranty is set to expire.
Good thing for AppleCare...

The fan must work hard mirroring from MBA to ATV and the computer gets very hot, solution?

I bought an Apple TV (3) for watching web tv by mirroring the screen. The picture is good but the computer gets hot, very hot. The fan on the computer is working hard and the sound of the fan interferes my TV watching. Is it normal that the fan is running as much as it does? It starts just after 3-5 minutes. Is there any solution?
My computer is a Macbook Air 13" i5 (mid 2012)

Hi Rudegar
I found this to be an interesting post... so...
I just ran a 13 min Youtube video from my Macbook Air (mid 2012) i5 on Air Play Mirroring to Apple TV3 and I didn't experience any appreciable heat nor any fan noise.
My MBA is encased in a clear Speck case, and my house temperature is about 21C (72F).
I just wonder if Hejmattias has something else going on or are we just seeing manufacturing variation?
cheers

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:

Does the iMac G5 get too hot?

Greetings to all.
I would like to start a thread about the iMac G5 and heat. I found a few old threads, but I would like to bring that topic up again.
I have a 1st Generation iMac G5 (purchased end November 2004). For the second time since November 2004, it was defective and the Logicboard was replaced (so my Apple Dealer told me).
First time, in November 2005, the screen went pink. Second time, earlier this month, my Mac didn't boot anymore.
The full amount for the repair (including shipping to Apple (Belgium), work hours, etc.) was over 500.00 euro (about 700 USD for you, Americans).
I believe that the iMac G5 (at least: my 1st Gen one) is simply getting too warm.
The day before, I installed "Hardware Monitor". It gave the following (average) temperatures:
CPU: 60.6 - 63.8° Celsius (141-164° F)
HD: 57.5° C (135.5° F)
It is my opinion that the (my) iMac is getting too hot to be "healthy". I have 2 PC's, in which I installed extra fans (at the back and at the side). One of these, with an Athlon64 3000+ (1.8 GHz) and a 120 Gb Seagate Barracuda gives (average) temperatures for the:
CPU: 36.5° C (97.5° F)
HD: 26° C (78.5° F)
My second PC, an old (modded) HP Vectra, with an Intel P4 at 1.6 GHz and a 80 Gb Seagate Barracuda, gives as average temperature (HD only):
HD: 37° C (98° F)
It may not be correct to compare my iMac with PC's - but harddisks are harddisks, wheather it is a Western Digital (250 HD in my Mac) or a Seagate (PC HD's), and it is only logical that a(n average) HD temperature of 57 degrees Celsius (128° F) in the long term can not be healthy, while the harddisks of my PC's are a lot, lot cooler.
The PPC, too, gets much hotter than my Athlon CPU (and the P4 most likely too).
Therefor: is my suspicion correct that the/my iMac G5 in general is getting too hot for its own good? Even though it may be summer here (Belgium), I still find such a difference in heat values between my iMac and my PC's not "right".
Both the times that my iMac was defective, the Logicboard was replaced.
Is it possible that in both cases heat is the problem (directly or indirectly) of the defects of my iMac?
Basically we have a desktop computer constructed like a laptop, with all the hardware stuffed together in a very tight space. Why did they not keep the heat issue more in mind, when the iMac G5 was designed?
I believe that the heat is a very negative factor in the/my iMac G5. If I will have to pay such a small fortune, every time my Mac breaks down, being a Mac owner will become quite expensive.
iMac G5 (PPC), 17-inch, Superdrive, Mac OS X (10.4.10) 1.5 GB RAM, 250 Gb Western Digital HD
iMac G5 (PPC), 17-inch, Superdrive, Mac OS X (10.4.10) 1.5 GB RAM, 250 Gb WesternDigital HD

Your Mac should have been repaired under the Apple power supply or video and power issues as long as your serial numbers were covered.
As far as normal operating temps are concerned, my Rev A is at this moment, running at CPU T-Diode 144∘and my Hard Drive is at 128∘so your temperatures seem well within normal ranges.
Yes, the machines tend to run a bit hot, but as long as the ambient temperature is not too high, they are fine. The failures were originally cause by a bad batch of capacitors but since those have mostly been replaced, the machines are much more reliable.
Some people train a small fan on the back of the computer to keep it cool, that may help you.
