Fan running indicate problem?
Hello!
I am a new owner of a brand spanking new iMac. Having just upgraded from the G4 model, I feel like I am riding the waves of the future. However, I am afraid I may have overdone it.
I was playing an online radio station through iTunes while running programs such as Photoshop, InDesign and FireFox when all at once, my computer just shut down! It didn't lock up or anything, just shut down. Once I restarted the machine, the fan was running at top speed. I did some research and was able to remedy that problem by unplugging the computer and plugging it back in while holding down the power button.
So, now the fan seems to be fine, but I am afraid that I maxed out the system and that is what caused my fan issue. Is that possible? I would think that this new system would be able to sustain that kind of workload... but maybe not?
Anyone have any thoughts?
Thank you!!
Ok... new issue. While running FireFox, Entourage and InDesign, the computer crashed again. Again, no freezing or anything, just a black screen. The difference is that this time once restarted, the fans did not kick on.
Could this crashing have something to do with running InDesign CS rather than the upgraded CS3? I just received the software for CS3 today, but have not had a chance to install.
All this crashing is a real disappointment.
Thank you in advance for any help!

G5 start up problem: stuck at grey screen with fans running full strength
hi, i'm new to discussions, so i hope this question and my technical knowledge and descriptions will be OK: problem: G5 20" stuck at grey screen with fans running full strength..
so far i've tried but did not work:
- power off by pressing the button for 5 secs,
- checked all cables connections etc, take out the power cable try again, etc.
- removed all USB connections, re-did
- tried to use it as 'target drive' connected to my macbook by firewire
- tried to start up and keeping C key pressed
- tried to start up with 'shift' key pressed
- tried to start up with command, options, P and R keys pressed,
- i had an additional RAM, i've taken it out and tried again, no luck
- i've put in Mac OS X install disc1, no luck, and now disc is inside my iMac, can't take it out
any recommendations? thank you!Scroto,
You may not actually have a bad processor. On the Dual G5's it's not uncommon after a few years for dust and corrosion to build up between the processors and their sockets. You can fairly easily remove the processors and clean the connections yourself if you're at all handy. Basically, snap off the heatsink covers, loosen a few screws and the processor and heatsink come out as a unit.
Clean the contacts on the processors (carefully). And clean the sockets. Be sure to put the same processor in the same place or you'll have issues.
I used 90% isopropol alcohol to clean mine last year. Let it air dry and blew both the socket and the cpu off after with canned air. That done, I reinstalled the processors, buckled everything up and no more "bad" processor... The machine worked perfectly from then on and I assume it still does today. Don't know, someone stole it last month:(... -
HP Pavilion a6110n Startup Problems, Fan Runs Full Tilt and then Shuts Down
We are currently running into an issue where our computer, when we try to power it on, turns on briefly with the fan running at full tilt. After a few seconds, the computer then shuts down and everything turns off. When the monitor is connected, we never do see anything show up there. We opened up the case and cleaned out the fan and the cooling unit completely, and then we even completely removed and then reconnected the unit. Still, the computer continues to do the same thing. Does this sound like a bad sensor? Like the computer thinks it is overheating and just shuts itself down?
Thanks for any help. We tried some of the advice we found on here, like stated above, and seem to have run out of options.Hi Big_Mike_180,
It is the same for the desktop or notebook. The one blink means that you are having an issue with the CPU, unfortunately. At this point if you are in warranty give HP Total Care a call at 1-800-474-6836 in North America or visit the link below if you are outside North America.

Or take it to a local tech to check the CPU.

My iMac won't start up, or wake from sleep. I've tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on, you can hear the fan run, but the display stays dark. Any ideas what to do? Thanks!
Mac doesn't boot
Can you hear the fans and hard drive and see the white boot screen? Flashing question mark? The circle just runs and nothing happens? Only black screen and nothing else? These can be very helpful to diagnose the source of the problem. [1]
Flashing question mark [2]: This is usually a sign of a failed hard drive. This indicates that boot up volume can not be found.
Black screen: This is usually a sign of a failed logic board. There is no single reason for this and this may be caused by failed GPU, screen, CPU or RAM.
Circle of death/no circle/blue screen: This is usually a sign of a hard drive failure. This may NOT be a dead hard drive, just broken permissions or something
Gray screen/Apple logo/spinning gear or globe/prohibitory sign/folder with flashing question mark [3]: This could be a sign of faulty hardware but more likely a software issue, i.e. broken permissions, failed software update, etc.
[edit]
What to do
First, hold down the option key (also known as the alt key) just after you've pressed the power button. This should show all the available options to boot from, so if you have Windows installed through Bootcamp or a disk in your SuperDrive, you should be able to see them along with your OS X drive/partition. Select the OS X partition with arrow keys and press enter. Startup key combinations
If that doesn't help continue doing the steps from below:
1. SMC reset [4]. Shut down and unplug all cables including power cord for at least 30 seconds and then plug in power cord and keyboard/mouse.
2. PRAM reset [5]. Hold down option, command, P and R while booting. Start it when you hear the sound and don't let go before it reboots.
3. Safe boot [6]. Hold down shift while booting to boot into safe mode. If this works, open Disk Utility from Utilities and repair your permissions and verify the disk
4. Hardware test [7]. Insert the install disk (disk 1 in Mac which shipped with OS X 10.5.4 or earlier, disk 2 if shipped with OS X 10.5.5 or newer) and hold down "D" before the grey boot screen opens. Follow on screen instructions
5. Boot from install disk. Boot from the disk that came with your Mac. Hold C while booting. Select Disk Utility from top bar and repair permissions and verify the disk. Reboot normally and see if it works now.
6. Boot from another Mac (Firewire target disk mode). Connect the machines with a Firewire cable. Power on your Mac and press T. Select the other Mac's hard drive. Download the current OS X combo update. Run the combo update installer and select the drive that won't boot as the destination.
7. "Repair" OS X. Boot from the install disk as in point 5. and reinstall OS X. This should NOT erase any data, just replaces the system files which may have caused your booting problem. Now install the latest combo update for OS X and repair permissions on your drive with Disk Utility.
7.1. Install OS X into an external hard drive and then boot from it [8] and try to copy your data from the hard drive before proceeding. If you have done a backup recently, you don't have to do this.
8. Restore OS X from Time Machine backup. Boot from the disk that came with your Mac and choose the Time Machine restore option. This step will lose any changes made since your last backup but the system and your data will be put back to exactly as it was on that date.
8.1 Reinstall OS X. Boot from the install disk as in point 5. and select Disk Utility again. Now erase the whole hard drive and install OS X again. If you had a Time Machine backup and step 7 worked you don't have to do this. -
Macbook Pro Fans Running At Full Speed When Macbook is Very Cooool
Ok, So now i'm pretty sick of the fan noise.
I've done PRAM reset, Power Management Reset to no luck.
So i decided to do some experiments.
As soon as the computer starts, Fans spool up to 6,000 and stay there. CPU Temp 42 Degrees Celsius.
Now My CPU temp does pretty well staying there. In Activity Monitor, No Processes of what so ever. Computer idles at 99% and only 1% being used by system.
So i decided to put the computer in the fridge. As soon as the temps went down 5 Degrees, to like 30 to 35 Degree Celsius, Fans idled at 2000 and as soon as the CPU temp is 40 Degrees, Fans spooled up and kept going all the way back to 6,000.
See as the temp drops on the computer, the fans do slow back down as the CPU temp drops from 40 to 35.
I called apple and the apple tech i talked to said that it seems the fan specs might be set out of whack. Meaning, the temps as which the monitor spools up the fans is set to low. He said it should be around 50 to 60 even 70 Degrees Celsius's before fans should spool up. He said the problem isn't the monitoring system since it does appear to be slowing down and speeding up the fans between 30 to 40 Degrees but it's spooling the fans up and to low of a temp than needed. He told me to take it to a Mac Genius sometime soon.
so before i do that, any apple geniuses what to take a stab on whats wrong and why it's doing this?My fan runs continually, BUT, with several monitors watching core AND fan exhaust temps I have noticed something strange. The core indicates 28C while the exhaust jumps from 42C DOWN to -128C and then the fan races. While this is keeping the book cool as a cucumber it is driving my wife and now me up the wall. NO I don't have any hung processes. NO the CPU is not caught in a cycle requiring massive computing power. Regardless of the temp the fan runs at the 6200RPM max. Zapping PRAM and resetting the System Management will soon be followed by gravity resetting through my 2nd story apartment window. One way or another this needs to stop!

G4 Wont Start Up No chime and fan runs fast.
Hi Mac Users,
I am at my wits end! My Mac won't start up.When I switch it on there is no chime and the fan runs fast.
I have checked the battery and it is OK.
Tried the reset button and no joy.
I have reseated the ram memory still no improvement.
I am completely lost without my computer would some kind soul point me in the right direection?
It is the hub of my recording studio and my life cos I'm disabled.
I have read a lots of posts on here and I feel I am getting confused with too much information.
My names not Dan but I am desperate?...........Dylan.The red LED indicates power to the logic board, which is good.
Try Resetting the Logic Board
Resetting the logic board can resolve many system problems. Whenever you have a
unit that fails to power up, you should follow this procedure
before replacing any modules.
1 Unplug the computer.
2 Press the Power On button on the front of the unit.
3 Open the side access panel.
4 Remove the battery from the logic board.
5 Wait at least 10 minutes before replacing the battery.
6 Make sure the battery is installed in the correct +/-
direction.
7 Reassemble the computer and test the unit.
Note:
This procedure resets the computer’s PRAM. Be sure to
check the computer’s time/date and other system parameter settings
Will your Mac boot using the Tiger install DVD (or another system CD/DVD)?

Why is my fan running continuously?
Hello,
I recently took my macbook pro to the Apple Authorized Servicer to get it worked on. Apparently the flex cable for the hard drive was bad, which caused my computer to not boot up when powered on. That issue was resolved, but literally 24 hours after getting my laptop back, it started having other problems.
My computer had many syptoms that were listed here: http://support.apple.com/kb/HT3964
Mostly these were the symptoms:
The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
The computer doesn't respond to the power button when pressed.
Battery indicator lights, if present, appear to behave incorrectly (on portables that use non-removable batteries).
The MagSafe power adaptor LED doesn't appear to indicate the correct activity.
The display would flicker while trying to boot up, then the whole system would turn off.
For a while, my computer would not even turn on at all. Now my computer seems to startup properly everytime. The battery indicator lights still do not function, but I can use the computer and all of my data is still as it was.
The main issue that still persists is that the fan runs at high speed all the time. My CPU usage is low, I checked in activities monitor, and nothing was out of the ordinary. I am not running any high CPU applications. And according to iStat, all the temperatures within my computer are running under 100 degrees.
I'm pretty sure I successfully reset the SMC, as when I held down the Shift-Control-Option keys with the power button, the LED on my magsafe changed colors, as noted it would in the instructions.
I would appreciate any and all help, as I am in Africa and another trip to the local Apple Authorized Servicer would be quite a hassle.
Thanks!The fan should always be running. Install another temperature/fan speed application to verify;

Running out of RAM & Fan Running
I have been having problems with my Mac Book since around Nov. 2010 which just continue to get worse. My system (now 10.6.8) continues to gobble up RAM though no programs are running. Had 2G of RAM that was using up 75% of the RAM so upgraded to 4G of RAM, within 2 days (& after restarts) am back to the system using up around 65% of the RAM. Fan runs & computer hot for no apparent reason, with just safari & this page open. Have added Privacy for my bootcamp partition in Spotlight, still seems to have the problem. Have reset the PRAM & SCM. Anyone else with this problem?
Looking at your Free RAM is a useless measure, as the goal of any operating system should be to take full advantage of all the RAM it can. Otherwise it is wasting your money because you paid for something the OS is not using, and worse, it is not taking full advantage of the best resource for allowing your system to run at its faster.
The operating system should be giving RAM to any process that needs it, and if the applications do not need it, the operating system should be using that RAM for a file system cache so you can avoid very expensive disk I/O. And by expensive, I mean expensive in time, expensive in power consumption, and expensive in wear and tear on your disk drive.
On Mac OS X, you want to look at both Free and Inactive memory to see how much memory is availble for processes to use. Inactive memory is often used a a file system cache. But Inactive memory may also contain the code for a recently quit program so that if you start that program again, it can quickly be re-activated from the cached code already in memory.
As Linc has suggested, you want to look at Activity Monitor and see if there is an app or daemon that is consuming lots of Real Memory.
If you think your Mac is using too much memory, then you might also run an Applications -> Utilities -> Terminal -> "sar -g 60 100" command, which should let you see your pageout activity once a minute for 100 minutes (adjust the numbers to suite your tastes). If mostly you have zero or very low numbers, you are NOT suffering from lack of RAM. If you have a few spikes, that might come from starting a new app, or switching between apps. If you have sustained pageout activity, that might indicate the work you are doing it stressing your available RAM and might benefit from running fewer concurrent apps, or getting more RAM for what you are doing.
It is very rare for the operating system itself to be the cause of excessive RAM usage. More frequently it is an app or daemon that gets memory hungry.
Also Linc's suggestion to boot in Safe Mode is an excellent idea, as that will eliminate any 3rd party drives, kernel extensions, or daemons. If the problem continues when running in Safe Mode, then that would increase your argument that it is something Apple provided. If the problem goes away when booted in Safe Mode, it tends to indicate there is a 3rd party driver, kernel extension, or daemom that is causing the problem. -
Mavericks keeps fan running all the time
I upgraded to Mavericks and every thing seems to work ok (except maps) but my concern is that now i hear the fan running slowly all the time. Even on battery power the fan runs. I don't remember this in mt lion, and wonder if this is normal with os x 9 or something i need to worry about. I would guess it would use more battery when not connected to the power supply. Any ideas as to this problem?
Some users have reported Dropbox is using an inordinate amount of power, but your system indicates nothing extreme. You might try uninstalling it to determine the result. Your Dropbox account won't be affected, and you can always reinstall it.
If you haven't yet updated Dropbox do so, because version 2.4 is required for Mavericks and a maintenance update was released only yesterday.
Also, there have been reports that an SMC reset has been beneficial. It is generally justified for any power - related anomalies including abnormal fan activity.
Follow all the steps, even if they seem unimportant. The power adapter indicator light should cycle off / on once when you reset the SMC.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer. -
My Powerbook will not power up, but I can hear the fan running...
Please help!! My Powerbook will not power up, but I can hear the fan running when I press the power button to attempt to power it up. I just received a new power adapter because it wasn't working properly and it was doing this before and then it worked for a week and now it will not power up at all. It just starts the fan but nothing else turns on. When I plug the adapter, with the battery still connected, it will look as if it is charging but then the light on the plug turns from green to orange then off and doesn't power up at all. If I take the battery out and plug in the adapter, the light stays on but it does not power up except for the fan noise. Does anyone have any suggestions? I also followed the two articles listed online in regards to resetting the power setting and the command + alt + P + R as well. Nothing works. Thanks in advance.....
Same here. If I start up with the power adapter attached, it starts up fine. If I try to start up from battery only, the fan comes on, the sleep light comes on but nothing else happens. I tried letting it sit that way for about 15 minutes and nothing changed. I tried attaching the power cord while in this mode and nothing changed. I tried the PMU reset a couple of times but nothing helps.
This computer is just over 1 year old and I have not had any problems with the power cord (3rd party), the battery, or any problem like this before. It started after a proper shutdown last night and attempt to start without the power cord this afternoon.
Any answers to this yet? I think I'll call on this and report any success to this discussion.

Macbook Pro fan running constantly and CPU running slow
So, I have a Macbook Pro 2010 2.3 i7 that has started running really slow and the fan is running constantly.
In activity monitor it shows a kernel_task running constantly at around or above 200%.
I have tried all the regular tasks. PRam reset, SMC reset and nothing seems to fix it.
I have also tried a system reinstall to no avail.
Maybe I'm on the wrong track, but from what I have read, the kernel_task might be trying to slow my CPU down because it thinks it is being overworked?
Maybe the fans are also being activated because it thinks the computer is too hot?
Anyway, if anyone has any idea as to what I can do to figure out what is going on, let me know. ThanksHere is the EtreCheck results:

Fan running at high when cpu not being used, Macbook not responding - Help!
Please help!
Quite often now when I leave my macbook for an a few hours (the screen goes to sleep but not the computer), I come back to the fan running at full speed and then when I touch the trackpad, I can move the mouse around, but nothing responds (i.e. when I move the mouse over the dock, the dock doesn't pop up...and I can't click anything on the desktop). So I have to hold down the power button to shut it off and then restart the computer. Then it works fine, but if I leave it for a while and come back, half the time I come back I encounter this problem again.
Any help?Check your activity monitor. Sounds like you have a program running in the back ground your not aware of.
You might also try to reset the SMC and/or PRAM. -
Will not boot up and fans run at high speed
will not boot up and fans run at high speed
after much head scratching I ran the hardware test disk from cd. The test showed a memory issue I eliminated the faulty one systematically. So it wasn't a hard drive or software problem in the end it was faulty memory. What was misleading was the computer telling me there was a fault on the hard drive. The machine works fine now. Thanks to people's comments I learned a bit more about the G5 that helped eliminate probable causes

24" iMac summer 2008. CPU fan runs at highest speed, some times goes to "sleep" mode. CPU t' is about 35'- 42'C. Run hardware test: 4sns/1/40000000:tlop-130.000, next time 4sns/1/40000000:tlop-128.000 errors. Tried SMC, NVRAM, PRAM. Reinstalled all softwere. Nothing changed.
I suspect you have hardware problem with a fan sensor. Doing a software install will not help the machine needs to be taken in for service. If you run Apple Hardware Test in Extended Mode it should reveal the error code. If it does not then run AHT an additional 2-3 times to be sure in Extended Mode. Each pass will take about 30-60 minutes.

Fan runs constantly (not my printer)
Hi,
I've had this problem for a while and it's really getting to me. The fan on my black MacBook (purchased April 2007 and treated very well) runs constantly. Not upon startup, but as soon as I open Firefox it's going until I shut down. I've read about people who had backed up print queues and clearing this solved the problem, but my print queue is empty and doesn't even show up on Activity Monitor. It also says that I have between 88%-92% of my CPU free. Any help is greatly appreciated.
I should also add that the CPU temp is between 66° and 69° C.
