Powerbook 12 heat and constant fans

So apparently this is a common issue but there are not many threads on this and no solution at all.
I just wanted to ask other 12 inch Powerbook users.. are the fans on all the time (during basic tasks like web browsing) on your machine... and any solutions??

In response to both authors, mine does the same, but it doesn't stay on all the time. But it does happen say, if I put my laptop on a desk with no air to breathe in between the underside, or when I put it on the couch.
When used on my lap, which I shouldn't be doing, but anyway, it will vary.
What I've done to solve the problem is to buy a laptop cooler and it really does work. It actually works better than the PowerBook's internal fans because for one, it doesn't generate heat (when my fans are on, it's because of the heat issue, but at the same time, it seems to circulate the heat as well, making it an infinite loop-- pun intended!!).
And with the laptop cooler, yes those fans are on constantly, but the laptop does not heat up.
I first tried Targus's laptop cooler (via OfficeMax) but found it aesthetically unpleasing, even though it is similar in color (aluminum colored plastic).
The one I ended up buying was a Micro Innovations laptop cooler from RadioShack (please don't laugh people), because it was black and matched my desk top--as opposed to the silver Targus one--and the best part is it's adjustable, so it works with my 12-inch PowerBook and my old Pismo.

  • HT1338 Problem: My Mac Pro is heating and the fan produce a lot of noise, what shall I do? I got the new Montain Lion

    Dear best Users,
    What shall I do? My Mac Pro 2.53 GHz Intel Core 2 Duo/OS X 10.8 13-inch 2009= Is heating and producing a lot of noise with the internal Fan.
    Best,
    Dario van der Lündin

    If you can, open Activity Monitor and see what's using up all the %CPU.
    If its kernel_task, shutdown immediately and do a PRAM reset, like this:
    1. Power down the machine.
    2. Locate the following keys on your keyboard in preparation for Step 4:
    ‘command’ – ‘option’ – ‘P’ – ‘R’
    3. Press the ‘power on’ button.
    4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
    5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should and with the kernel_task process back to normal.
    If that's not it, try quitting whatever the process is by selecting it in the Activity monitor window, then 'Quit' in the task bar. If the process refuses to quit, post back with the name of the process.

  • Safari causing heat and excessive fan use, had to switch to Chrome

    Lately, every time I open Safari the computer heats up and the fan blows continuously. This doesn't happen for Chrome, so I've had to use Chrome exclusively lately.
    In Activity Monitor, Safari Networking has an energy impact of 100 and Average Energy Impact of 77, which Safari has an Average Energy Impact of 162. Chrome is at 11.
    Any help would be greatly appreciated!

    Usually due to Safari extensions and or plug ins.
    From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
    If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
    If it's not an extensions issue, try troubleshooting third party plug-ins.
    Back to Safari > Preferences. This time select the Security tab. Deselect:  Allow plug-ins. Quit and relaunch Safari to test.
    If that made a difference, instructions for troubleshooting plugins here.

  • I have Heat and high Fans Voice if i play games

    macbook pro i7 2.2 2011
    i have Heat and Voice of the fan is too high  if i play games on mac os x lion or bootcamp windows 7
    Is this problem is not good for macbook pro ?

    If you are askiing whether heat and fan noise affect the machine, the answer is no, as long as the internal temperature remains within the machine's safe operating range. Keeping it within that range is what the fans are doing and why they are making noise. If the temperature exceeds that safe range, the machine will shut itself down.
    If you are asking whether the heat and noise affect the user, of course the answer is yes, the user will notice them.

  • Powerbook G4 667 constant fan

    I recently cleard off about 5 gigs of various junk like old apps, files, etc. to free up space on the HD, and since then my Powerbook has been running extremely hot with the fan running constantly with only Safari running! I've repaird permissions and done fsck/ but nothing helps. Any ideas?

    Open System Profiler and check the Machine Model ID. If it says 3,3, then you may need to install a firmware update.
    I assume you have 256 MBs of RAM or more installed?
    It is possible your initial installation did not complete successfully. You might try the following (after making a bootable backup of your current 10.1.x system.)
    1. Boot from Tiger DVD. After the installer loads select Disk Utility from the Utilities.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Check the DU status bar for the SMART status report. Do not proceed unless the SMART status says "Verified." Otherwise, click on the Partition tab in the DU main window.
    3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
    After the formatting is completed quit DU and return to the installer. Proceed to install OS X.

  • GT 70 missing graphic card and constant fan noise Issues

    Not even sure if this is the correct place to post this thread if not could someone move it to a different section.
    So today for some odd reason my laptop decided to freak out on me. I get a bluescreen saying VIDEO_TDR_FAILURE, I have GT70 NVIDIA GTX 675m I was doing a scan on my computer and the lower right hand corner it said Application has been blocked from accessing Graphics hardware. So before it kept saying that over and over again. The computer basically just lagged out and I did a hard shut down to turn it off. I turned it back on and it started up to the BIOS for some unknown reason I didn't press any button so then I go over to Save & Exit and it said do you want to save the changes, I said no and it started up again to the desktop but very slowly.
    Then my desktop finally shows up but now I hear what appears to be my video card fan or the fan that turns on when you are overclocking or just when you hit the fan button on the keyboard constantly running. I am freaking again myself because I don't want this laptop to die on me. My NIVIDIA card is no longer even showing up on the taskbar, even when I go to control panel I click on the NIVIDIA control panel and it doesn't even come up. So I try doing a system restore, after it restarts the video card is showing up I do a couple of restarts to get things back in order again. Even the fan is no longer blasting like before which puts me at ease.
    I go to watch a YouTube video and then the video freezes then in the lower right hand corner I couldn't see what it was because it faded away something about the video card crashing so then after it crashes my fan starts to go off again and I am freaking out again. I tried to do another system restore but it seems that it's not working any more. Is my video card dying or do I need to install new drivers for it.
    How come it's no longer showing up on my device manager? Did it die or something?

    It has been acting very strange today. I turned it off last night and went to sleep, woke up a couple of hours later to turn it back on and it went to the desktop very slowly but my GTX 675m card showed up in the display under device manager also the fan was working normally like it usually does and not constantly going. I was sort of shaking my head not understanding how it showed up again.
    So I took it into a computer repair place to see what they might make of it. Won't get any word until tomorrow or Monday to see what it might be, strange enough when they booted up the system at the computer place it booted up quickly and he told me that the GeForce Experience thing opened up and all that. But I don't really trust the laptop, I told them I would still like for them to check it to see if my GPU is really dying. They said they will run some tests to see if it's a hardware problem or software problem.
    As for buying a new GPU I am not sure i want to pay that much, is there something more cheaper that might be better than 675m? I keep hearing people saying how bad the 675m is and how NVIDIA does not care much for that particular card. Also my 2 year warranty for the laptop just expired in January and I have no idea why this always happens to me once the warranty expires something wrong happens, not sure if it's a coincidence or just bad luck.
    Guess I will see what happens when I get the computer back from the repair place, paid $89 dollars just for them to check it which they say is a lot better price than Geek Squad cause they would have me paying $200. Ugh! This crap makes my anxiety go sky high. Hate to lose my laptop, I mean it seems to boot up to the desktop but that stupid cooler fan going full blast is what concerns me.

  • Heat and fast fans during gameplay...

    I can get about 20-30 minutes playing a game until my MPB starts to overheat at 170 F. The fans blast off to about 3500rpms and the game gets very bogged. The MBP is on a flat surface the whole time.

    Even though it helps out some people i'm not a fan of apps that take control of your fanspeeds, the MBP has it's own software built in to handle this and it works good for me.
    When idle my fans run at 1900 - 2000 rpm.
    When i make my MBP sweat and work hard the fan speeds can run up to 6000 rpm each and it will keep my temperatures well within acceptable ranges.
    The hottest it ever got was 79C and that only lasted a minute or two.
    With a Core Duo 2 MBP the minimal fan speed should not be less than 2000 rpm and the max. fan speed 6000 rpm. Running the fans flat out all the time will probably shorten their life.
    I'd say on normal use anything from 2000 - 3500 rpm is normal.
    The fans can take a beating and run at full speed for a few hours or in bursts no problem.

  • Heat and the fans not kicking in to chill things.

    So today i just hecked iStat Pro and noticet the temps and fans were not kicking in to cool thing down i made a screenshot here it is. To be honest its hot outside so that is why my Ambient is that high, i was sinking my ipod and waching some YouTube that is all.
    Opinions and Answers are verry much appreciated.

    Just run smcFan conservatively. I've never had any problems with it on this late 2009 21.5.
    Here are my settings. During the winter, I run at the defaults or just above. Right now, it's 97F outside. I'm often running on my second lowest setting, Minimum. The fan at the back helps a lot.

  • Hot Hot Hot. My Powerbook is hot and the fan never turns on!

    Hi,
    I downloaded the istat pro widget in order to monitor the heat and fan on my Mac. Currently the CPU top is 141 F and the CPU bottom is 140 F. The front and rear fan are not on and it seems like they should be.
    When are the fans set to turn on... can I change this?
    Are my fans not working.
    Give me your insight. Thanks!

    Look here:
    Apple Specifications
    http://support.apple.com/specs/powerbook/PowerBookG4_15-inch_1_67-15GHz.html
    Electrical and environmental requirements
    Meets ENERGY STAR requirements
    Line voltage: 100V to 240V AC
    Frequency: 50 to 60Hz
    Operating temperature: 50° to 95° F (10° to 35° C)
    Storage temperature: -13° to 113° F (-25° to 45° C)
    My computer temperatures are constantly on the upper end of the scale, as well as frequently going over the operating specs listed by apple. I believe these are environmental conditions for operation, but currently my cpu temps are 120/114 according to istat, so this should give us some ammo for repairs, a recall, or something, as the obvious internal temperature is not within Apple's operational specs. Even my powersupply is 109f currently...
    This has got to be wrong... Lets fix it apple!

  • I just recently did an update to my computer that the app store told me to update. And now my battery is draining and my computer is heating up and the fan is always on now. What do i do?

    Just did an update that the app store told me i needed to do. The computer had to be restarted and everything im running verson 10.8.4  i believe it was a RAM update. What do i do? I feel like this is bad for my computer and i dont want it to overheat and what not.

    Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity

  • Much better- and question about constant fan noise

    i couldn't start anew thread a few minutes ago. I replied to 2 threads, then the startanew thread iconmagically appeard! I am not making it up.
    any way- i posted a while back about noise. I thought it may be the hard drive. But definatley it sounds like the fan(s) in my MBP dual core
    my MPB was silen when i first bough it. then a few month in it got noisy. Now thw fans are on all the time.
    anyone else with a MPB that is just noisy? this *****! macs are almost always quiet. this is annoying acually. and it is non stop! i can't recal a moment when the fns were not winding like tiny air craft jet engines! LOL wel, it's not that funy actually.
    the noise does change in pitch on occasion. sort of like they slow down a tiny bit. other wise they just hum away.
    I had a G-4 I mac- SILENT! then a dual G-5 tower- it was quest until it roared up on a task, then it roared with power then got quiet again.
    but this tiny mpbis just noisy!
    Well, i hoope it is the fans, not the HD. It prettty much sounds like fans, and constant.
    but considering theroom temp is abou 68 in here, whywould the fans be on? and non stop?
    we live in a cold climate, so it's not a 100 weather.
    any help with the fans and perhaps a test or a way to turn them down? does my system think the core is hot?
    thanks for any help

    only about 13% is a peak ap. nothing major, nor a lot of stuff. but nothing consuming 30 40 or more percent or anything. Nothing running except safar in this case, activity monitor.nothingexcessive like 10 aps , whihc i have done in the past as we know the macs can handle it
    well, nothing seems out of the ordinary.
    I included a pic from that FAN CONTROL AP- well was going to, but not sure how.
    any way my stats from it are:
    base speed, 1500 rpm (on both actually)
    ower threshhold 122F
    upper 176F
    current temp at that moment was 101F
    can someone compare their fans to mine and their temp- i assume it is the cpu core temp.
    any way, not sure what is a safe range, nor why my fans are running non-stop.
    just noisy? but like i said they do occilate a little ans slow and the hum gets deeper then they go back to normal which is a slightly higher pitch.
    as for that iStat pro ap. i opened it and it just made my application dock bar flash then the dock came back. The Istat pro didn't open.
    Um- it looks like a widget. I may have taken my widget ap of some time ago. I hve yahoo widgets on. but not sure how to get that istat to work. I can't even recall the name of the apple widget program.
    thanksfor help on tracking this noise down-
    are any of your guys's fans really noisy? is this common? mine is just non-stop but if my settings are off or if there is areason, then I can adjust it from there. just want to know what the "normal range" or operation of the fans are. but man they are noisy for a mbp. and they WERE QUIET when i first got this laptop.
    thanks again

  • Pavilion dv7 - heating and fan problems, hinge broken - DO NOT PURCHASE THIS JUNK!!!

    This message is targetted towards people looking to purchase an HP Pavilion dv7 series of notebooks. Hopefully they are scanning these boards prior to purchase, something I (very) regretfully did not do.
    My system: Intel i7 Q720 @ 1.60GHz, 8GB, ATI mobility radeon HD5650 1GB, Windows 7 home premium 64 bit.
    Almost immediately, there were severe overheating problems. Even under normal use (1- 4% CPU, Word, Excel etc.) it became too hot on the left side to keep on my lap. My kids actually burned their hands on that part. I once used it on a table with a vinyl tablecloth. It actually melted the vinyl!
    Running any CPU/GPU intensive software causes a shutdown due to overheating, a real nuiscance with playing games or watching video in HD. Just as a test, I ran one computationally intensive program overnight while I kept the machine in my freezer. Even then, it overheated and shutdown! (I have not overclocked; just running my software on the hardware as purchased).
    Even in normal use, the fan runs very high, and is very noisy. It is so noisy that I cannot leave it on in my bedroom.
    Finally, because of the positioning of the vent, I am certain that the intense heat weakens the left hinge. I am very careful with how I open lids, always with both hands on the lid. Within two months, the left hinge cracked. I argued extensively with HP, but they insisted that it was my fault, and I was charged for the fix.
    I'm wondering whether the designers ever turned on (let alone stress tested) these units prior to selling this piece of !@#$.
    Added bonus: within 4 months, the hard drive failed, though I can't pin that on HP. While the drive was getting replaced, I went out and bought an Acer. It had better specs than the HP, was cheaper, lighter, and even with the CPU at close to 100 percent, the heat is hardly noticable, and the fan is barely audible.
    I bought HP because most of the scientific instruments in our labs is manufactured by HP, and it is truly high quality , high precision equipement, some of it running for over 25 years problem free. From that, I really trusted the HP name, I trusted that their PC division would have equal quality and standards. !#$% was I wrong! I'm glad they're getting out of the PC business.
    The only reason I'm keeping this junk is because I took the extended warranty at the store, and under it, after three major repairs, they will get me a new notebook of equal or greater value. I can't wait for that inevitable third breakdown!

    The dv 7 eg 4012  is the biggest disapointment:
    the hinge brakes, it has an overheating problem!!!
    Be prepared to replace it after 12 months or pay the bill for the repairs, hundreds of dollars.
    I purchased the laptop directly from the hp online store about a year and a half ago.
    First of all I had to install the latest drivers because hp is not making sure it comes with up to date drivers.
    To find out what the problem was I had to contact the costumer service about 6 times.
    After about 12 months the laptop startet splitting at the left hinge.  The HP Costumer Service looked at the photos and told me this, Quote:  "We have received the attachment of broken hinges and find it is an user damage hence, the service of the Notebook would be done on chargeable basis."
    Before you want to buy a hp laptop, please type into google:  broken hinge hp laptop
    And you will see hundreds of posts of disappointed costumers.
    Even class action lawsuit have been taken out against them.
    For me, this was the last time that I invested about a 1000 Euros( bought it in Europe) in a product which needs to be replaced after a year and a half.
    Please stay away from this product,
    except you have plenty of time and money to keep this machine alive.

  • HP ENVY 14 Heat and FAN issue

    Hello Team,
    I am having an issue with my new HP ENVY laptop.
    I purchased it because some of my application uses lot CPU and I found this laptop can fits my requirement.
    Now IF I use this application ,My laptop burns like anything and  heat is that much as i can not even touch the air wings .....
    (running dynamips application)
    Second issue is the FAN...Sometime its having lots of NOISE (without  running my apps) and its relay annoying to hear that voice(same like Datacentre server noise)
    I already bought cooling pad and i think my BIOS is also updated.appriciated your inuts ASAP.
    my config  is as below.
    BIOS Version:              Hewlett-Packard F.13, 27-08-2010
    System Model:              HP ENVY 14 Notebook PC

    Virtual Memory: Available: 9,027 MB
    Virtual Memory: In Use:    3,126 MB

    i may have just fixed it without even trying to!
    i saw the new mountain lion thing, and saw that there was a beta for Imessage on the mbp and i decided to download it, and since that download, it started cooling back down and the fan turned off for the first time in almost a day without me putting the computer to sleep myself!!!
    i dont know if it will stay like that, but hopefully it was just a freak thing!!
    EDIT: NEVERMIND... THE LOUD FANS ARE BACK...

  • World of Warcraft from Core 2 Duo to i7: heat and fans

    Hi,
    I've been playing World of Warcraft on my 2008 Core 2 Duo 2.93MHz for some time now, with moderate rendering settings, at 1024x640 in window mode so I could check mail and other things. I was very satisfied with the whole thing.
    I recently upgraded to the top 2.66MHz i7 with 8MB RAM. With exactly the same settings WoW now uses apparently more CPU cycles and brings CPU heat between 70° and 90°. Therefore fans quickly jump towards 6000rpm. I tried to lower the settings, to no avail.
    And I thought with that new machine I could use WoW with full resolution and settings...
    Is there something I should be aware of?

    Hi
    My i7 macbook pro also runs very hot, i.e. 90 degrees when playing Championship Manager or Dragon Age Origin with all settings at max.
    Mind you, the i7 in the macbook have turbo boost speed around the same as you old macbook, also it have hyper threading which increase the core temperatures.
    So overall, the i7 have more transistors than the core 2, so it will produce more heat and require more air flow to cool it therefore faster fan speed.
    for me, I've stooped play games on the macbook for the reason as I don't want the CPU to operate so close to its maximum temperature for long period of time.
    I'm don't think its harmful to the macbook to play games continuously. But I don't think the macbook is not designed as a game laptop, and no other applications I use stress both the CPU and GPU close to 100% at the same time for any long period.
    But I do have a PC if I want to play games.

  • Heat and fan on new MacBook Pro:

    I got a new MacBook Pro. This is my second. The first never had this problem.
    The new one differs by having a larger hard-drive 750GB and 8GB of memory but
    is otherwise very similar.
       But with the is new one, it get very hot on the bottom (below the keyboard) and the
    fan keeps running, probably trying to cool it doen.
      Is there anything I can do to keep the machine cool (short of leaving it in the refridgerator
    overnight)? and can I reduce the fan noise?
    Thanks in advance

    The only thing that takes up more than 10% is firefox, which has gone over 50% on occasion.
    I like to keep many firefox windows open. But I guess I shouldn't do that.
    What is interesting is that if put the computer into sleep mode and then wake it up, it turns off the
    fan for a few minutes.
    But something is different between my old 4GB Macbook Pro and this new 8GB one.
    It is alot noisier and hotter.
