PowerBook fan control software?

I know of this software for controlling MacBook and MBP fan speed:
http://81.169.182.62/~eidac/software/page5/page5.html
but it is Intel specific. is there something similar for PowerBooks, specifically the second to last 17" model?

As far as I can tell, no, there isn't. I've searched and haven't found any.
Actually, if you keep your PB on a cooling platform.....I use this: http://roadtools.com/) whenever using it, your PB should virtually never overheat. I've been using Temperature Monitor: http://bresink.com/osx/TemperatureMonitor.html and, currently, Hardware Monitor: http://bresink.com/osx/HardwareMonitor.html for the past couple of years and have NEVER seen my PB go beyond 142 degrees F.
The left fan cuts in when the PB's temp reaches about 140 F and deactivates when the temp drops to around 130 F.
The right fan will activate only if the PB's temp reaches critically high levels, perhaps 160F, but it's never activated since my PB has never even come close to critical temp.

  • Fan Control Software

    I am trying to install the new version of SMC Fancontrol on my Intel Santa Rosa MBP. When i try installing it tells me that there can be no other fan control software running. My question is how do I turn off the existing software, and/or what am I doing wrong. I want to be able to turn up the fans whenever I need to do model and image rendering.
    Thanks a lot.

    It should do that automatically depending on how hot it gets.
    If it doesn't do this run a hardware test to see if there are fan or sensor problems.
    As for the SMC fancontrol problem, no clue, maybe email the developer.

  • PowerBook Fan Control

    My powerbook gets super hot and I was wondering if there was a way to control the fan and make it turn on at a lower temperature and to a higher rpm. This kind of software seems to be available to intel based mac notebooks, but I haven't been able to find one for powerbooks.
    Thanks!

    Hi,
    You might want to take a look at the link for laptop cooling devices. I use one and it keeps my Powerbook's CPU around 50'c (120'F), which is a drop of around 10'c to what it operated at before I got it. There is a fan controlling app you can download, but I wouldn't recommend it because it will definitely shorten the life of your internal fans. Have a look at some of the coolers available.

  • GS70 2QE (970m)- Any Fan control software?

    I am looking for a Fan control utility that will work for the GS70 2QE, This is a brand new laptop of the latest generation.
    I would like to turn the fan speed up manually during heavy computing loads to avoid the bouncing of the CPU clock due to thermal scaling. (Cools down, clocks up, gets hot, clocks down).
    Thanks

    Wondering how it worked? Can share with us?

    I've just seen fan software for GT70 - no idea if it could work for a GS.

  • Fan Controlling Software Issues with K8N-Neo4-F

    My mobo is a K8N Neo4-F 3.0.
    1. Is there anyway to control the Northbridge and System fan using Speedfan? I searched so far without any solutions.
    2. I tried MSI Corecenter for a while (the last version), and it triggers the alarms and atempts to shut down the system without any visible reason everytime the PC comes backs from hibernation. I have the latest BIOS and latest drivers on my PC. What could be wrong?

    It could be the sensor is bad on the system fan or the header itself. Is it possible for the wire from the NBFAN1 to reach the CPUFAN1 and the wire from the CPUFAN1 to reach the NBFAN1?  That way we could test to see if it's the fan or MOBO header? I'm not sure this is possible, but it occurred to me as a test.  According to the manual, both headers have the same configuration and 12V feed. I think the amp specs are the same for both headers(someone that is better with electronics should speak up here). Make sure you have the CPU fan set to 100% or whatever as I'm not sure if the NB fan can or should be speed adjusted.
    According to page 2-16 of your manual, it only mentions control of the CPUFAN1 header:
    Quote
    Fan Power Connectors: CPUFAN1 / SFAN1 / SFAN2 / NBFAN1
    The CPUFAN1 (processor fan), SFAN1 (system fan 1), SFAN2 (system fan 2) and
    NBFAN1 (NorthBridge Chipset fan) support system cooling fan with +12V. It supports
    three-pin head connector. When connecting the wire to the connectors, always take
    note that the red wire is the positive and should be connected to the +12V, the black
    wire is Ground and should be connected to GND. If the mainboard has a System
    Hardware Monitor chipset on-board, you must use a specially designed fan with
    speed sensor to take advantage of the CPU fan control.
    MSI Reminds You...
    1. Always consult the vendors for proper CPU cooling fan.
    2. CPUFAN1 supports fan control. You can install Core Center utility
    that will automatically control the CPU fan speed according to
    the actual CPU temperature.
    3. Please refer to the recommended CPU fans at AMD® official
    website.
    But, In addition to finding out about this issue, I can't stress enough about getting a better PSU.

  • Fan Control Software for iMac G5

    do you know any software that makes me able to control the fans of my imac. I want to change the speed of my fans.

    You can control the fan speed to a certain extent by going to system prefs>energy saver>options>processor perfromance and selecting "reduced". This should slow your fan speed down, but I am not aware of any software program that will contriol your fans speed. It wouldn't be a good idea anyway to interfere with the settings the machine selects for itself, the iMac is very sensitive to heat and shouldn't have fan hacks.

  • 27" hot at the top. FAN Control Software??

    I've heard the fans on this thing go really high during startup. Is there any software I can download to have fun control over my fans in my 27"?

    I like http://www.lobotomo.com/products/FanControl/index.html as it is more complicated than FanControl.

  • Custom Hardware Fan Control - problem if speed pin not connected?

    Hi There,
    I am planing to install a hardware fan control (poti) to my MacPro 1.1 rear fan. (because I have a defective northbridge temperature sensor and the fan is running at maximum speed... so i thought of slowing it down with a fan control for the pci slots)
    I read that the pinning of the Fan is: Gnd, 12V, Speed, Control Pin (analog Voltage)
    So when i would attach a fan control (just a poti) between some +5v and the Control Pin I think I should be able to control the fan manualy - am i right?
    But then the speed signal is not the speed the mac pro fan control software think of... so would it be a problem e.g. if i disconnect the speed pin from the mainboard fan connector?
    what would happen then? is the mac pro powering up the other fans for some kind of failsafe?
    Or have you other suggestions how I can lower the speed of the rear fan manually?
    thanks in advance,
    Stefan

    Take a look at the project some have undertaken to go with water block.
    Send the motherboard in to have a 'skilled' electrician? repair the board perhaps.
    4 fans, 3 under the control of SMCFAnControl utility. Maybe disable the one fan and make up for it with your own fan and running the others efficiently.
    There are also VGA copper coolers.
    FBDIMMs bleed heat: maybe the RAM fan cooler kit in there to deal with large source of heat. New higher density DIMMs are better made and few DIMMs = less heat even if 4GB.
    Use ice packs, dry ice and liquid nitrogen to super cool :-)

  • No fans working withouth Lubbo's fan control

    Hi.
    I recently installed on a Boot Camp Partition, Windows 7.
    I installed correctly all the drivers using my iMac installation CD, in windows. However i can't get the fans working, if i don't use Lubbo's Fan Control software: this is the only way to get them working.
    But this software if for the macbooks, so i can't get the fans work properly.
    My iMac is a 2011 model, if you need to know
    Can someone help, getting my fans working correctly on Boot Camp?
    Thanks to everyone.

    Apple has a big weakness and this has always been an issue.
    I used InputRemapper for years also.
    Windows on Mac is less than 100%, enough so that while I still (right now) running 7 on Mac Pro, I ended up building a couple PCs too.
    For a long time - over a year - my hope was to get SpeedFan to work, but that never happened.

  • What Fan Cooling software to use on imac? (Leopard 10.5.1)

    Hello,
    I'm a frequent online user (online games, websites) and I would like to know what kind of fan control software can I use to cool my imac.
    If you suggest one, tell me what specific settings I need to cool my imac properly.
    Thanks,
    Michael

    Energy Saver in Apple menu -> System Preferences can manage performance of the machine within specs. No other fan control software does it within spec guidelines, and could without meaning to cause the machine to overheat if it turns off the fan when the machine needs to cool down. Please identify your iMac:
    http://docs.info.apple.com/article.html?artnum=301724
    and see if it is under one of these exchange programs to see if the power supply may need fixing so the fan operates only when necessary:

  • Battery and smc fan control

    will running that software do anything that would kill your battery faster than if you didn't?
    thanks!

    The design idles the fans normally at 2000 RPM which is sufficient. Fan software does nothing more than increase the idle speed of the fans. That simply means the fans won't increase in speed until the temperature sensors report a higher temperature than would have normally caused the fans to ramp up. For all intents and purposes all this does is keep the computer cooler during idle. Unless you keep your room temperature very high or do not allow proper air circulation, there's little need to use fan control software.
    I have both a first and second generation MBP and neither computer requires any fan control software and they both run normally. I've had both for two years now.

  • Does using a program like fan control damage my mbp?

    I heard good things about this program so I downloaded it and it cools off the machine wonderfully. However, I was wondering if it caused damage to the machine as the fans are running at about 3 times what they ran before? Does anyone know anything about this? Thanks.

    I would hazard a guess that if it did have anything to do with the failure of the hardware in any way, the manufacturer would void your warranty. Any repair needed would be chargeable.
    Mac OS X, Boot Camp and the EFI firmware all have system settings created by the manufacturer. Using a program which alters their recommended settings or changes the behaviour of hardware devices within the machine, goes against the terms of the warranty.
    I would ask Apple about Fan Control and get them to confirm that any damage which may be caused (or may not be caused) by a third party program willl not void your warranty.
    In some respects, it's like overclocking a PC. Whilst it may be more beneficial to the system and provide better performance, the maufacturer of the computer can not be expected to repair something which has been damaged by the end user 'tweaking' settings to get better performance.
    In the case of Fan Control, I have not used it so can not refer to the licence terms, the liability of possible damage done to the machine by using this program will either be at the end users own responsibility or the manufacturer of the software. This should be checked prior to installing and using the program.
    I would suggest any program which alters the running of the machine will invalidate your warranty in the event of hardware failure.

  • Fan Control

    I would like to control the fans on my Mac Pro. Does SMC Fan Control void AppleCare? Is there a way to control the fans without software?
    Thanks

    You can control the video card. I never had trouble in Vista with InputRemapper but that is getting old. Under Win 7, seems fine w/o any except eVGA Precison. There is a generic graphic tuner, and if you have ATI be sure to install their latest Catalyst.
    And use something like SpeedFan just to monitor temps.

    Can Lenovo enable the fan control option in the EM?
    I know I can install other versions of the EM software but, I won't have the yellow color improvements found in the Yoga specific EM.

  • How to use fan control?

    I just downloaded fan control because it sounds like a good idea to keep this puppy cool. What is a good setting that isn't going to be overkill. I don't want to compromise battery life too much. Anyone good with this program? This is for my MBP 15"

    I see nothing there about "firmware" specifically. "...non-Apple products" could refer to any third-party software.
    Some might argue that (e) applies, but these fan utilities don't "significantly alter functionality or capability". None allows settings below Apple's default 1000 rpm setting. Nor do they defeat the default Auto fan mode, which increases fan rpms as the temperature increases.
    Most of the people passing on warranty scares are well meaning, but the facts don't support their contention.
    These fan utilities in no way resemble the thermal paste mods that were kicking around these forums a few months back. Remember? And even then, some here maintained that mod (where you actually open the machine) did NOT void the warranty as long as there was no damage done.
    Heck, Apple doesn't even warrant their own software!
