Mac mini appears to be shutting down due to overheating fan is running, but not strongly

late 2012 mac mini shuts down after running several minutes in a streaming task environment. Fan is running, but not very forceful. wondering if the fan itself has a temperature sensor that causes the fan to engage in higher rpms or if that sensor/command comes from somewhere else in the computer

Install a temperature/fan speed app.. I use the free Macs Fan Control app downloaded from the internet. Yes, there are temperature sensors that contorl fan speed

Older Mac Mini Shuts Down due to Overheating

After researching this issue extensively and trying every suggestion, I finally began placing icepacks underneath my Craig'slist purchased Mac Mini to keep it cool. I must also keep the blinds shut to minimize solar heating and sometimes run the ceiling fan in my office. I also must watch the temp on SMC FanControl to make sure it does not rise above 130°. I'm now looking for an external cooling fan which I hope will keep this situation more permanently under control. Does anyone know of a good one? Remember, external fan, not internal. My hardware info is :
Hardware Overview:
Model Name: Mac mini
Model Identifier: Macmini2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: MM21.009A.B00
SMC Version (system): 1.19f2
Serial Number (system): YM824031YL2
Hardware UUID: 00000000-0000-1000-8000-0016CBB0A806

To diagnose this, one really needs to know if the Mini's internal fan speeds up (and gets noisy) before the thermal shutdown occurs.
Not sure why you brought up "liquid cooling systems": the Mini has a standard CPU heatsink. There is no liquid cooling anywhere in the Mini.
Sometimes the contact between the CPU and heatsink gets compromised and the Mini can no longer keep the CPU cool. This is more likely to have occurred if the Mini has been modified or upgraded by the previous owner.

Mac Mini LED blinks and shuts down at startup, takes 2-3 tries to boot...

I have a Mac Mini PPC 1.42GHz. When i boot it up after non-use (cold), the LED blinks once per second and it boots all the way into MacOS and shuts down several seconds later. It will usually do the same thing the second time around. On third boot its usually fine. Not thinking its related, I have reinstalled MacOS anyways. No good...
Thanks,
Rich

Welcome to Apple Discussions!
The flashing LED is usually indicative of a power-on self test failure, normally leading to the system failing to boot at all. Once per second would indicate the system fails to recognize available RAM.
The fact this happens when the system is cold (with an implication that it doesn't happen when the system is warm) might indicate the RAM module is no longer firmly inserted, or that the contact face on the pins has oxidized slightly. In this situation, I'd begin by opening the system and removing and then reseating the RAM - in the G4 minis this is relatively easy since there is only one RAM slot, and it is exposed with just the top of the casing removed.

Macbook Pro i5 2.4Ghz shutting down due to overheating

I recently upgraded my 5yr old Macbook Core Duo to a nice, shiny new Macbook Pro i5 2.Ghz. I'm absolutely in love with it in every way possible except for one issue I'm having:
When I play Company of Heroes on Windows 7, I've had the Macbook shut down three times so far. After the first time, I felt the area just above the F1 / F2 keys and it was extremely hot to touch. I downloaded CoreTemp and Hardware Monitor to test for temperatures and discovered the Macbook is set to auto-shutdown once CPU temperatures reach 105C.
Is this normal? I've had the Macbook for four days now and wondering if this is a common problem. I've since gone out and bought a Coolermaster NotePal U2 notebook cooler, but I am a little reluctant to do any heavy gaming on this now.
Should I take this in to an Apple Service Center to be checked?
Just to clarify, in an airconditioned room with ambient temps of 24.5C, using the Coolermaster stand, the Macbook is idling with temps of:
CPU #0 53C
CPU #1 57C
Low 50C
High 97C (during Company of Heroes 5 mins ago)
Thanks in advance

Hardware Monitor had them running at 5517 rpm or something close to that. Perhaps Windows 7 has less effective power / fan management than Snow Leopard, I don't know. I've been wanting to try out a game from Steam for OSX so I may post back with more results.
What I'm worried about is the fact that it is shutting down at all. Safety mechanism or not, I would rather my computer not shut itself down while I'm in the middle of doing something.
Just on a side note, I found that sliding the Macbook down off the rubber pads on the Coolermaster stand so that the bottom vent is directly over the fans of the stand dropped the idle temps in OSX to 36C. Pretty impressive. If the Macbook is placed as it is shown in the instruction card (on the rubber pads) the idle temp goes up to 41C.

Tecra S3: Notebook shuts down due to overheating

Whenenver I run CPU-intensive processes on my laptop, the computer's base and the table become untouchably hot and the laptop shuts down without any warning after a certain time.
What can I do?

Hi Kersten
May I ask you how long do you use this notebook??? Did this issue appear in the past???
Mostly such overheating problems happen and are present because the cooling modules dont work properly the dust and debris inside the notebook prevents the fans from rotation with full performance this rises the temperature to the critical level and the notebook shuts down automatically to prevent the hardware from damage.
So in such case its advisable to check the cooling modules and to clean it. The vacuuming could help but be careful such procedure could damage the fans!!!
So maybe you will ask a technician or a Toshiba service partner for a help and for a professional cleaning
good luck

TS2446 If my iTunes account was shut down due to fraud activity why can I not use the same credit card if I choose to when I have no other way to pay

When I turned in my iTunes account b/c fraud activity had been detected while my iPhone was not working so they disenabled my iTunes account but I got my new apple id back to download free games but I can't use my debit card anymore and want to use the same card as that is the only access I have as a form of payment

You can give feed back to Apple from the iTunes drop-down menu in the iTunes menu bar..
You can also contact the iTS Customer Service from the links on this page - http://www.apple.com/support/itunes/store/

Anyone else seeing their MBP's shut down due to overheating and no fans?

I have a 2 month old MBP that overheats and locks up when playing World of Warcraft in OS X. The processor temp will get to 100-105 and the MBP locks up and requires a forced hard boot. The fans don't spin up - they stay at 2k.
Also, on the Windows side (64 bit Vista), the upper left hand corner of the chassis gets extremely hot - again no fans spin up.
I have resorted to using smcFanControl to manage the fans in order to prevent overheating. I have seen many people post about this exact same problem on these boards - does anyone have any advice? I am concerned that I am frying the hardware over time!
I called Apple tech support and they say they have no knowledge of this being an issue.

No problem here, at first my fans were stuck at 2k regardless of the temps. I reset the SMC and that (at least for me) fixed the problem.
While I use and advocate the use of smcFanControl, I recommend that you get your laptop repaired (or replaced). Now with that said, there seems to be quite a number of threads of WOW users who complain about the heat being generated from using that game and likewise, it seems pretty evident that using Vista means your laptop will be running hot for what ever reason.
If your fans are not ramping up beyond 2k in OSX, then that's not right, if its running hot in vista or playing WOW then that might be another issue.

Mac shut down due to problem; I rebooted fine. how do I determine what the problem was?

mac shut down due to problem; I rebooted fine. how do I determine what the problem was?

When shut down and rebooted, the Mac OS X does background maintenance on the system. That can solve minor issues.
Beyond this, it is a good idea to run Disk Repair yourself just to make sure.
Reboot with the option key held down. On the screen that comes up select the Recovery disk icon and Continue.
On the next screen Clcik Disk Utility and Continue.
In DU, in the list on the left select the drive to be repaired - click the item that is indented to the right, not an an item whose name starts on the far left.
Click First Aid, then Repair Disk.
After that is done, quit DU and restart as usual.

Mac book pro trys to shut down while downloading?

my mac book pro trys to shut down while im downloading for some reason..

Hi Monroeeugene,
I'm not sure if you mean shutting down or going to sleep ... but this article will explain how to change your sleep settings so your downloads don't get interrupted.
Mac Basics: Set your preferences
http://support.apple.com/kb/ht2490
Change your Mac's sleep settings
To conserve energy, all Macs have the ability to sleep. When you haven't used your Mac for a set amount of time, it enters a low-power mode until you wake it by pressing the keyboard, trackpad, or moving the mouse. Sleep doesn't turn off your computer; it merely puts it into an inactive state that consumes less power.
Open System Preferences
Choose View > Energy Saver.
Choose the Power Adapter or Battery tab. If you're using a desktop Mac (a Mac mini, iMac, or Mac Pro), the Power Adapter and Battery tabs do not appear.
Move the sliders for both the computer and display to change the times in which they go to sleep.
Select any other options you want, such as sleep and wake.
Hope this helps ...

Mini Server won't shut down/won't start up until power is pulled

I am running OS X 10.9.1 on a Mac Mini Server 2.6 GHz Intel Core I7 / 16 GB ram. I have been having issues shutting down my Mac. I start the shut down process but it gets to a gray screen/beach ball and will sit there forever until you hold the power button down. I tried shut down again with all external drives disconnected and get no change.
Also, if I leave Mac on sometimes I can login normally and sometimes I find out that it has actually shut down completely by itself. It is not sleeping. I can't seem to turn it on unless I pull power cable.
I have checked temp of unit and it appears to have plenty of ventilation felling only slightly warm to touch. My keyboard is wired and I have a Bluetooth touch pad.
I re-installed the latest "Mavericks" just to make sure but no change. Seems like the shut down issue may have started 1st before I upgraded. When I do get Mac to start back up everything seems normal, no errors. The only thing barking is Google Chrome stating that I can start where I left off. I have not caught it shutting down so I thought it had something to do with the Energy Saving settings but it is at the "Default" setting.
The Mac is definately off and not sleeping, no light on front.
Any tips or help would be appreciated.
Thanks

OK, I tried setting Energy Savings to 1 minute. The Mac shut down and would not power back up via the power button, had to pull power plug. So it seems to be tied to the Energy settings.

Now the macbook will not turn on at all

If you're able to boot, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.
If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.

IPod shuts down due to "low battery" even when fully recharged

OK..
I got big problems with my iPod battery.
I've already sent my iPod to Apple once, but they returned it saying nothing is wrong and giving "helpful" tips about turning the backlight off in order to make the battery last longer..
Well, I sorta disagree about there not being any problem. And I did feel a bit insulted about the claim that my iPod is not malfunctioning as well as the hints about me being a retard who needs to be told that using the backlight continuously might have an affect on battery life.
(but in case my retardedness is to blame for all my problems with my iPod, please let me know. )
During he last 2 months or so, the iPod keeps shutting down due to "low battery" even though it's been connected to the USB port for, like, 20 hours straight.
Tried different ports and computers without any luck.
The recharging-icon is usually moving while connected to the computer, but I don't get the "battery is fully loaded" message (or icon?) anymore.
Sometimes when the iPod has shut itself down due to low battery, it can still be used for ~10 hours by turning it on/resetting multiple times. When that happens, the battery icon is at first "empty", but then bar suddenly goes to half full.
I also suspect that resetting it 7 times before plugging it into a USB-port helps. Occasionally.
No way to tell if there's 15 hours or 15 seconds life left in he battery. I just got got home from a 2 x 8,5 hour flight and the iPod shut down right after the first take-off So.. yeah.. I'm ****** off atm.:/
I've tried all the tricks I've found on the net (resetting, software updates etc.) but nothing helps.
Don't know if it could have any relevance, but it seems like the problem appears more often when playing audio books - long mp3 files, that is...
Help, anyone? Pretty please?
PC Windows XP

I have the exact same problem. About 2 weeks before the end of my 1-year warranty, I contacted Apple about the problem. They sent a box with prepaid shipping (I paid for it) and I sent the iPOD back to Apple. Today, I checked the status of my repair and the screen reads:
Step 1 - Request
Product received (05-Apr-2006)
Step 2 - Service
No trouble found (11-Apr-2006)
Step 3 - Return
Original product shipped (11-Apr-2006)
I contacted Apple Customer Service and was told that they ran diagnostics and nothing was wrong with the unit. I asked them if it mattered that I noticed problems with the iPOD that they don't seem to see and they said no. They said the problem could be with my charger, but I told them that I recently lost my charger and had used several different chargers that work with other peoples iPODs just fine. I even left it to charge overnight and the next day I could barely play one song. The woman I spoke with told me that if I had any problems with the iPOD after it was returned to me, I would have to send it back (they would not provide the box) and pay $225 since it is no longer in warranty .
My problem is that the unit was in warranty when I sent it, they didn't fix it (they couldn't find this very obvious problem), and now it isn't in warranty. The only way I can listen to music is to plug it into an A/C outlet while it is playing. My other option is to buy another mp3 player.
Has anyone else had this problem? Have you found a solution? Thanks!

Just updated my RAM and now iMac shuts down "due to error" when in FCPX

Hi there,
So, I just purchased FCPX last week. Edited one of my projects only to find that my RAM is overloaded and isn't allowing my computer to handle to workload. Therefore I upgraded my RAM today to the max (16GB). Get my iMac home and up and running, everything looks good. I start up FINAL CUT PRO X, load my Library.....then boom.....shut down "due to error". THREE TIMES. Below is my system and info on new RAM. PLEASE HELP ASAP AS THIS IS TIME SENSITIVE! I upgraded my RAM due to the suggestion that it would solve my slow rendering/choppy video playback in FCPX.
Thanks. Ashley

My 5th ten iPod is basically doing nothing but trying over and over again to start up. I've tried to restore it, but when the logo apple appears, it simply shut down.

my 5th ten iPod is basically doing nothing but trying over and over again to start up. I've tried to restore it, but when the logo apple appears, it simply shut down. Then I've connected it to my macbook pro, and I've seen the script "Please Wait - Very Low Battery", but, after some time, the iPod tries to start up again, and nothing happens. It's a kind of noise, I'm thinking about the hard disk, (it's a 80Gb version), and I'm listening to it; every 30 seconds seems to try to open and then shut down again. I can't see the iPod in iTunes too. Don't know what to do. Can someone help me? Thanks a lot, it's my first forum

It sounds like the battery could be going bad as well as the iPod's Hard drive. You'll want to have the iPod serviced either by Apple or a third party repair company. Here is Apple's pricing:

Google for "iPod repair" and you should get a ton of results to work with.
