IMac ALS gets too hot!

My 20" iMac ALS gets hot very quickly and goes to sleep. Looking at the system log after it happens shows:"Thermal Manager: max temperature exceeded for 30 seconds, forcing system sleep". I cleaned the fans intake on the bottom, opened it and cleaned the exhaust but that didn't change.
Does Apple have a fix for it?
Thank you.

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.

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.

HT3964 IMac, Mountain Lion- overheating and putting itself to sleep when it gets too hot.

I've tried re-setting the SMC on my intel core i5-2.66 GHz Imac 27" to stop the fan from running all the time. It started when I first upgraded to snow lepeard. I thought maybe Moutnain Lion would help this issue, but now it's overheating and putting itself to sleep when it gets too hot. Any suggestions? This happens after about two hours of working. Using Adobe Suite only and still overheats.

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
First off, there is nothing wrong with the fans running all of the time, they are the Macs cooling system and they would not run under normal conditions if the Mac didn't need them to run. So unless they are racing and your Mac sounds like a jet ready for take off, the fans are just doing their job.
That said, I think Apple's idea of how mcuh and how fast they should run does not always match the iMac's real needs. I, like many others, use SMC Fan Control and I set the speed at which my Mac's fans run.

Macbook pro retina display 15" charger getting too hot... any advice?

I have had my Macbook pro retina 15" since Jan 2014 and it has been working fine. Just recently, I have noticed that the charger block and the connector to the laptop gets extremely hot as does the actual laptop. I have looked around on the net and most of the discussions regarding this have been on earlier models. The charger block itself is so hot that it emanates heat and is too hot to touch! The plug into the laptop is pretty darn hot as well. When charging, I can't keep the macbook on my lap because it gets too hot.
I have checked all the connectors and the connections of all bits involved and they all seem good. I have also tried to minimalise all programs that are running.
Just wondering if someone can suggest anything, otherwise it looks like a trip to the store
Many thanks in advance

Bfore you run to the store try this SMC ret, it fixes

My iphone 4s gets too hot with ios 6

Hi Everyone. Just joined the community. I noticed since I upgraded to ios 6 on my iphone 4s it has been getting too hot when in using it. i noticed it would get hot when using maps and playing games. it would not get this hot too quiclky on ios 5.1.1. I also read that some iphone 5 users have the same problem as well as 4s users with ios 6. Can anyone give me some feedback and info. on this ? Hopefully there will be a fix for this soon.

Mines never did that until recently. It depends on your usage and apps.
It's basically normal to get hot, especially charging. Now if you talking about oven hot then you have a
Problem. All my friends iphone 4s does it, so it's normal. Streaming videos while multi tasking can cause it also.

Pin connector of ze2308wm notebook ac adapter gets too hot

My pin connector of my ac adapter gets too hot whenever I'm working on my ze2308 wm notebook. It doesn't whenever I set it on "Standby." Is this normal like that of ac adapter?

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.

So bring it to Apple for evaluation. Can you not figure that out by yourself?

My new 32gb iPhone 5 gets too hot during phone calls. Is this normal?

My new 32gb iPhone 5 gets too hot during phone calls. Is this normal?

Mine will get hot mostly if I'm in an area with poor reception. The phone will juice up the power output to lock onto a signal and will cause it to get hot and battery will drain much faster.

Having problems with phone getting too hot when not in use

Hi there -- I'm trying to figure out what I can do to fix this. Recently I had to get a replacement S3 because my original shut off mid-use and wouldn't turn back on. The replacement has been here for about a month and in the last 2 weeks I'm having issues with it getting too hot. The first time it happened, I had it plugged into the stock charger for about 1 1/2 hours - and I had picked it up expecting it to be fully charged but it was extremely hot and had a warning on the main screen saying that the battery was critically hot and was not charging and the phone was nearly completely dead. I unplugged it, took the battery out and let the main phone body cool down. After about 15 minutes, the body felt like room temperature again, so I put it all back together. It turned on, charged normally that night and all was well.
Now for the last several days, I'm having issues again with it getting hot at random times when I'm not even using it (and not charging it). The last time, I downloaded a temperature app and it said the phone was nearly 105 degrees, and it felt the hottest right at the home button. Later that night after it cooled down, I noticed that the battery wasn't charging at all and was depleting rapidly on the charger. I restarted twice with no change and then took the battery out and let it sit for several minutes. After that it began charging again.
With it getting hot so much more often now, I'm starting to worry about this happening when I need my phone for an emergency as I spend a lot of time on the road transporting my kids to school and activities. Is there a fix for this? It doesn't appear to be the battery because my husband and I have the same phone and I've already swapped batteries with him - same issue for me, no issue for him. Please help? Thanks!

Hello Micheliu813, let's get to the bottom of this together! Are you using the same charger that came with the phone or a 3rd party charger? We can also test the phone in safe mode to see if the device heats up again. Check here for steps: http://vz.to/1kb9LUM

My phone gets too hot Everytime I use it, why? I don't know what to do!

Everytime I use my iPhone 5s it gets too hot. I've done everything. Even while charging it gets too hot. It's been like this for 2 days straight and I am compeltely baffled. I barely have any apps on my phone so I dont understand as to what the problem is…any help?

So what does 'everything' mean? You've done each of the following 4 troubleshooting steps; restart, reset, restored from backup, restored as new? If so then you likely have a hardware problem and it needs to be examined at an Apple store.

My iPad gets too hot to handle! What's up with that?

I have the new iPad 3, and it gets too hot to handle... Is apple gonna fix that or what?

There probably is no fix for it. Contact Apple or if you bought the iPad at an Apple Store, make a Genius Bar appointment, show them the iPad and they will replace it if the device is faulty.
There is no way that it should get to hot to handle - mine barely gets warmer than my original iPad does. Take it back, get it replaced.

My Ipod touch 2nd gen. was working fine but when I tried to charge from my PC the Ipod start getting too hot and the screen turn black and doesn't work anymore.Maybe is burn?

My Ipod touch 2nd generation was working fine until I tried to charge again from my PC,when I connected the Ipod was getting too hot and smelling like burn cable,the screen turn black and doesn't work anymore. any ideas about what happen?

You can try here:
iPod touch: Hardware troubleshooting
However, from your discription, I suspect that something is broken. Maybe a dead battery. In that case. I would make an appointment at the Genius Bar of an Apple store and see what they say.

MacBook air get too hot

I have MacBook Air 11 Inch.
It's get too hot whenever I used MacBook. Also whenever it gets hot my Mac get slow.
It was not like that when I bought it.
I like to format my Macbook Air. Like I like to have my MacBook air like first time I got it.
How i can do it?

well you cant really fix that issue but if you run heavyt apps it tends to overheat but it will not damage the machine thats why they have fans to coll them off
if it gets really hot then take it to the apple store and there might be a problem with the cooling system

First mac, is it getting too hot?

Hi, I just bought my first macbook pro a couple days ago (15 inch 2.2 ghz, 4gb of RAM, 500gb @7200rpm) and was wondering if it is getting too hot. I have been playing a game on it and have been noticing it that it is getting pretty hot, so I downloaded SMC fancontrol to monitor the temperature. While I'm playing the game the temperature is anywhere between 80 and 85 degrees celcius at a fan rpm of anywhere between 2500 and 3600. I am just wondering if this is too hot or should be a concern to me. Thanks a lot.

I would say those numbers are too high. Considering you can coagulate tissue at 70C. If those temps (80+ celcius) were correct, you would probably have permanent grey patches of skin that would eventually slough off leaving holes on your lap. Ha ha. Seriously though those temperatures would coagulate your tissue.
If you're concerned, get a secondary surface thermometer. Also I think there are companies that sell lap covers to put your computer on while you work.

Mac Pro in Desk will it get too hot?

Hi I'll be receiving my Mac Pro on the 27th of March. I will be placing it inside my desk (not by choice as I have no other place to put it) It's surrounded on all three sides, there's no door, the front is completely open, Would it get too hot for my Mac Pro? Would it be best to cut an opening in the back of the desk behind the computer? Thanks

Would the computer be ok if I plugged in an external usb powered fan and have it blow the heat out?
Would something like this do the trick?
