Imac Top hot to touch

Hi Peeps,
I have an Imac and I have just noticed that the top of the casing is very hot to touch. Verging on burning your hand if you leave it for a few mins.
I have seen this is normal???
If this is the case, is is still safe for it to be left on all the time... also I'm only using email and internet so i'm not pushing the processor or other components to the limit.
Thanks
Gary

The internal fans should be keeping the temperatures within spec. If you are concerned about the temps, want to view the fan speeds, or want to increase the fan speeds to make the computer run cooler, try downloading SMC Fan Control. I began using it after the NVIDIA graphics card in my 24" failed. By running the CPU fan faster, I was able to get another 3 months out of the card before it totally died. Now I run all the fans a little bit faster than stock, in an effort to prevent the card from failing again, and keep the rest of it cool also. Not like jet engine fast, but a few hundred RPM above normal.

The back of the iMac is meant to get hot. It acts as a kind of heat sink. But if it's really too hot to touch that's not good. This is probably in the upper left corner of the back as you face the screen; it is where the power supply is located. Get Temperature Monitor (free) and post all the results, including the power supply temperature. It looks like you've been running something graphics intensive, perhaps a game or something with Flash content. This will always raise the temps.

Actually, I don't see anything terrible in those temps, at least those you posted. But they might be lower. You might want to get smcFan Control.

Not including the default, I have five fan settings increasing in increments of about 20% to around 2K. I give them different names such as "minimum," then "minimum plus" etc.
From experimenting, here's the way I use smcFan (you may find your own preferred method): I would start out at the lowest setting above the default. This will be approx. +200 rpm. See how the temps are looking using that setting. If needed go higher in steps. But you don't want to run the fans constantly at 2K. That may shorten their life.
When needed, I also run a small 6" clip-on fan mounted to the wall just behind my 21.5. It helps dissipate the case heat.
Make sure you keep the air intakes free of dust. I vacuum mine periodically, with the computer shut down.

To Hot To Touch

I just got my MacBook Pro with retnia yesterday. Its my first mac. I am extreamly unknowlagebale about macs. Last night when I went to bed I plugged it in to charge. This morning when I went to get on it, it was incredibly hot, both the top and bottom, to hot to touch. Is this a normally prob.? It cooled off rather fast. Im just really concerend about my computer well being.

The machine should have gone to sleep overnight, unless you changed the default Energy Saver settings, and when it's sleeping it won't generate any heat. What was it doing this morning when you first discovered it was hot?
It's important to understand that a MBP can get quite hot when doing very processor intense tasks, or if it is used on an inappropriate surface. If you leave it running for a long period of time while it's resting on a soft, insulating surface (like a bed), this can not only trap excess heat on the bottom of the machine, but it can also cause the vents (hidden in the hinge) to be at least partially blocked.

IMac runs hot after Mavericks upgrade

after upgrading from Mountain Lion to Mavericks the machine (mid 2010 IMac 27 inch) runs much hotter than before. I was hoping the power management would rather be better than worse. The upper part of the enclosure get too hot to touch comfortably without excessive load e.g. just some office programs and safari running. This even now in winter time when room temps are only about 20 deg C = 70 deg F. The fans are running higher than before.
As no topics like this are found, a general compatibility issue could most likely be excluded.
What should be checked?

Do 2-3 SMC Resets, or it also may simply be re-indexing Spotlight. Check Spotlight to determine if that is the issue by hitting Command + Spacebar and see if it's reindexing.

I want to bring over music from my iTunes library on iMac to an ipod touch with another apple id. please help

I want to bring over music from my iTunes library on iMac to an ipod touch with another apple id. please help. Is this possible. In former versions of itunes this was posible. I can't find the solution is iTunes 11

Perhaps those apps require a newer version of iOS than is compatible with your iPod.

How to I get my Canon MX700 to scan to my new iMAC top? Currently the Canon will print from the iMAC. They are on a wireless home network. The Canon use to scan to the PC using software called MP or Navigator.

Hot to touch and battery drained

Has anybody's Iphone5 is ever hot to touch and battery drained at the same time.

Too hot to touch

My PowerBook often gets too hot to touch on the bottom. Is that because of a faulty battery? My batteries' serial numbers don't match those of the recall.

You might be interested in reading this thread:
http://discussions.apple.com/thread.jspa?threadID=602676&tstart=0
It's possible the heat is coming from something other than the battery. 3rd party RAM or defective RAM will commonly cause overheating problems. Try to figure out exactly where the heat is on the bottom and run the diagnostics suggested in the other thread.

Sleep and to hot to touch problem

I'm reading all these problems about the MBP getting to hot to touch while sleeping (not).
I haven't seen anybody put all there specs down. I think it is a graphics card driver problem but can't be sure because not everyone has said if they're using "Better battery life" or "Higher Performance".
We never have this problem with our two new MBP's unless we are using "Higher Performance" If we remember to change to "Better battery life" our MBP's never get too hot to touch. However, the few times we've forgotten to switch and left them on "Higher Performance" they've gotten too hot to touch while sleeping. I say sleeping but not really, as they never really go to sleep in this mode.
One of our MBP's is a 2.8 the other is a 2.53.

sounds like you have a hardware problem I would take it into a apple store

Dv2500 notebook - extremely hot to touch

Running Vista, no error messages but notebook is very hot to touch within a short time after it is on. Has anyone else experienced this and what to do about it. This has been happening for a long time now - no significant software or hardware changes before or after first happened. My optical drive stopped working and I think it has something to do with the heat of the notebook. It is not the battery as same with or without battery installed.

Shuffle hot to touch, won't hold charge

But it will play if connected via USB post. May one safely assume the battery is toast (and thus the device itself)? No Apple store or service here, so off to the tip if my suspicions are correct. Comments/advice welcome

ipod shuffles do get hot when charging normally
Really? My 2nd generation iPod shuffle (silver, but from the neon color revision) does not get hot at all when charging. It warms up so slightly that you can barely feel it on touch.
but not to hot to touch. Yep too me it sounds like yours is dead for good.
Maybe it isn't broken, but the firmware got corrupted somehow. I'd suggest an attempt to restore it (preferably with the iPod Reset Utility) before giving up on it.

IPhone hot to touch

Is it normal for a iPhone to be hot on the back side? Cause mines sure does.

I have had an iPhone since June 30th. It has been enclosed with an iCase skin since the middle of July.
It should not get hot with or without the skin on. Normally when the iPhone heats up it is due to one or two things.
1) You may have a malfunctioning battery. If the second item listed below is not the cause, you should take the iPhone back to Apple for an exchange. This can be accomplished through the store or AppleCare.
2) If you have too many functions operational at any one time, such as YouTube, WiFi, internet, it is possible for the phone to heat up. If the iPhone, as you say, is too hot to touch, that is not normal. Too many functions will warm the device. Make sure that you have stopped those functions that you are not using and then see if it warms up as you indicated.

Iphone hot to touch when removed from holster

After a couple days of carrying my iphone around in my pocket I needed a case for my belt. I went online and ordered a case that stated “iphone” with a magnetic flap which is what I used with my blackberry. After a few hours in the case I took the phone out and it was HOT to touch. It also had no service and gave me some error stating I should contact Apple support. I powered the phone on/off and everything was back to normal. I tried the case again with same results. Is the magnetic flap causing a problem?

It sounds like your case may not be the culprit.

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...
