Is it bad to have the fans running?

Is it bad for my macbook pro to be playing counter strike source for long amounts of time which makes the fans run this whole time?

If the fans are running, then it is unlikely to overheat. I would be worried if it was getting hot and the fans DIDN'T come on. So I think they are doing what they were designed to do.
As the other poster observed, the real issue is WHY are the fans running all the time? Are you running some apps that are heavily stressing the CPU?
Open Activity Monitor (In your Utilities folder) and click on the CPU column so that the highest percentages are at the top. What processes are at the top, perhaps at 100%?
Cheers!

  • Is it bad to have the fan running loud all the time

    the fan on my macbook runs loud and long at times. is this bad for the machine?

    Is it possible to have 2 threads running at the same
    time at different times eg 1 repeats every 20
    miliseconds and the other 40 for example. Yes.

  • TS1433 I have tried to reset the SMC and still have the fans running. What else could be causing this?

    My iMac has been continuously running its internal fan. Sometimes with just the internet running, or upon startup. I put it into sleep mode and wake it back up, which turns the fan off, but sometimes it starts back up shortly after. I have tried resetting the SMC by powering off and unplugging. Anything else that could be causing this?

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.

  • 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.

  • TS1587 I 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 Maja

    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.

  • Ibook want start - only the fan runs full speed

    Hello to all,
    my problem, when i start the ibook only the fan runs in fullspeed, thats it.
    to shut down the ibook i have to remove power and accu, the powerswitch do nothing.
    pmu and nvram reset does´nt help. the first problem was that date/time will lost, than after view days he does not start. is the problem the Backup battery? And how to change?
    thanks to all for help

    Hallo Wein and welcome to Apple Discussions ,
    my problem, when i start the ibook only the fan runs in fullspeed, thats it.
    to shut down the ibook i have to remove power and accu, the powerswitch do nothing.
    pmu and nvram reset does´nt help.
    Well try this and see if it helps:
    http://www.coreyarnold.org/ibook/
    If so it's U28 on the bottom of the board. The shim fix will work for a good time but a permanent repair is to have the chip resoldered. $40 at Superior.
    the first problem was that date/time will lost,
    That's because the power is interuppted.
    is the problem the Backup battery? And how to change?
    There is no backup battery or PRAM battery like in the PowerBooks. There is a .22 Farad super capacitor that will hold settings for a while but not long. Meant to allow a battery change.

  • Often I will leave my office and return to find the fan running at max speed and the computer is unresponsive

    I also have a MacPro3,1 (2009) I believe and just started experiencing similar issues as described here.
    I have scheduled sleep and start cycles and often I will leave my office and return to find the fan running at max speed and the computer is unresponsive or I find the computer booted in to disk utility mode.
    I also often loose ethernet connectivity and have to try renewing DHCP lease several times before it will finally work.
    Has anyone found solutions for this. I have looked at the console errors right before shutdown and don't really see anything fishy. Here are the last couple of lines before it looks like it shutdown.

    Mac Pro early 2009 is Mac Pro4,1, anyway, I think you need to boot into recovery mode, launch Disk Utility, then select startup volume and run repair disk.
    Xcode is the latest one, by the way?

  • Graphic issue but goes away if I keep the fans running

    So I have a graphics problem where I end up with lines covering the screen and screwed up video, however I am now certain this is due to overheating however I am not able to get new thermal paste for a week or two because of shipping. I am asking you if there is a way to keep the fans running at maximum output as when I have booted up the mac from a firewire drive, the graphic issues go away, but as soon as the fans start to die down it comes back within seconds.
    Thanks

    The graphics issue may well not be lack of thermal paste, but a failing logic board. Have you run Apple Hardware Test or Disk Utility
    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk.

    I suspect you didn't reset it right.
    Turn off the machine, let it charge up and then try the SMC reset again.

  • Mega PC 865 Pro - should the fan run all the time?

    Samsung SpinPoint 250GB SATA II Hard Drive SP2004C
    1GB Kingston Hyperx 512 DDR400 PC3200 CL3
    Intel Pentium 4 630 3 Ghz Socket 775 800Mhz 2mb
    LG GSA4163B 16X DVD Dual Layer R/RW/RAM
    TV@anywhere-Master TV and FM Radio card
    I'm sure I read that the CPU fan should not be runniing all the time? The fan runs constantly even when I'm not working at my PC. Is that normal? The box does not feel hot at all and I'm not running the TV card.
    It's not that it's noisy but I had hoped it would be silent, like my Pentium M laptop. The fan on that only starts up when the computer is working hard, and then very rarely.
    Thanks for a great forum. Imagine relying on MSI!

    i don't know about the 865PRO, as i've never used one, or seen one in action
    but on the other Megas, the fan usually rotates at a slower speed, until the temp increases under CPU load, then it speeds up to compensate
    P4 Prescotts are hot CPUs anyway, and if they aren't installed correctly, they'll run hotter. try removing the heatsink, cleaning off all the old thermal pad, and using a good thermal compound such as Arctic Silver 5. apply a thin layer to the CPU die surface, and then refit the heatsink. make sure no stray cables are blocking airflow to the CPU heatsink fan.

  • Will running games that make the fan run loudly and the computer heat up damage my machine?

    On my Macbook Air running Yosemite 10.10.3, with 4 GB RAM, 251 GB storage (170 GB free), a 1.6 GHz Intel Core i5 processor, and Intel HD 6000 1536 MB graphics card, when I play games such as Batman Arkham City, I experience very smooth gameplay with high fps. The only thing that worries me is when I play, the laptop heats up very much and the fan runs pretty loudly. Even with old, less intensive games like GTA SA, the computer gets pretty hot and the fan runs loudly. Is this damaging the computer, or can I continue to play these games?
    Thanks.

    Yes you can continue to play games but heat is the bane of electronics and in time there will be a cost.  When is hard to say, but I can put it this way, a fan running constantly at high speed is more likely to fail sooner than one at a slower speed.
    Ciao.

    There is excessive swapping of data between physical memory and virtual memory.
    That can happen for two reasons:
    You have a long-running process with a memory leak (i.e., a bug), or
    You don't have enough memory installed for your usage pattern.
    Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
    In the Activity Monitor application, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the  Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
    View ▹ Columns ▹ Real Memory
    from the menu bar.
    If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
    The process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.
    If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
    The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command: 
    sudo leaks -nocontext -nostacks process | grep total
    where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.
