Default fan control

I installed fan control on my macbook pro 15''(late 2011). Can anyone tell me default fan control settings?And is there a chance that changing fan settings can damage my macbook? Thank you

Does anyoe know how to reset te SMC for a 2008 Macbook Pro if I dont have the battery? My original battery died and swelled up so I threw it away... I use the laptop like a desktop now.
I installed Fan Control for a couple of live sound mixing jobs because it was getting REALLY hot and I wanted to keep the fans on max for the whole performance...
Anyway I have deleted fan control now and I cant reset the SMC because part of it requires the battery

  • Lobotomo Fan Control

    Ok got my MBP 2 days ago.. installed Lobotomo's Fan Control. Read on the internet that once you install it, it messes with Apple's preset fan-adjusting option in the firmware?
    On the download page for this software, it even says "For safety, it leaves the original automatic fan speed control intact."...
    I followed the instructions on their page for uninstall.. how do I make sure that Apple's original thing is still intact? Should I just goahead and use smc Fan Control?
    I'm freaking out a little here... new 2500$ laptop lol

    I don't know about outsmarting the engineers, but I know these little facts:
    1. my new iMac 24" 2.8 Ghz with default settings is running in excess of 70 degrees centigrade for power supply (like 78 at high load) - and default fan control does not do anything about it - fan speed stays at lowest setting.
    2. When I raise the lowest default fan speed a little (from 1200 to 1500 or 2000 for CPU fan, which also cools the power supply) - I manage to keep my power supply within 60 degrees at all times.
    3. I don't have factual knowledge of how long my power supply is going to last if operated at 70C and above, but my guess is that keeping it below 60 WILL PROLONG ITS LIFE!
    also remember that smart engineers only care about 1 year warranty period, while I care a bit further into the future!

  • SMC fan control and default Mac settings

    Hi,
    I've started to play with setting fans speed manually on my Mac. So I installed Lobotomo FanControl 1.1 program. Then I've installed smcFanControl 2.1 for MBP.
    However it seems that Lobotomo FC changed default minimal Mac settings and now in smc, the minimal possible rpm setting for fans is much higher that it was before I started to play around with changing fan speeds. So I think the original Apple settings for fans has been lost. How can I restore them?
    Thanks,
    Michal

    I forgot to add that before installing smc I uninstalled Lobotomo Fan Control according to their website instructions.

  • User-devel​oped Fan Control for the S10(e)

    Hello and welcome.
    When you've searched the internet and found this thread, it's possible that you are an owner of a Lenovo Ideapad S10 or S10e which has a little problem with the behaviour and/or the noise of the fan. In this post you will get all the informations you need to handle this problem for yourself. It should also be the same on every S9/S9e.
    Just a few comments before we begin:
    This is not an official support or solution by Lenovo.
    We are just normal users as you are, but we get rid of the fan and wanted to find a way to handle it. So if you want to try anything of the methods described here you have to know that you'll do all this only at your own risk. We are not responsible for any damages of your device. You should only use these methods if you know what you are doing.
    Please note that this thread is only for discussing, improving, trouble shooting and perhaps extending the fan control utilities. Any general complaints about the fan problem itself should be placed in the original thread right here: http://forums.lenovo.com/lnv/board/message?board.i​d=IdeaPad_Netbook&thread.id=795. It already has 80+ pages (the link goes to the first page) and it is better to exclude all the fan control stuff because there it's very difficult to keep an overview.
    Here you may post all of your questions, ideas/brainstorming, concerns, thanks and so on and you are really invited to participate and be an active member. 
    In this first part of this post I'm going to summarize all information about using a fan control utility. For any newbie it will be enough to read this post to get all necessary information. The second part does the same for developement of fan control utilities as we still have no known or working fan control utility for Linux, Mac OS X and other OSs I've forgotten - for now.
    For getting started you need a S10 or S10e with an up-to-date BIOS. For the S10 it's the 90 67, for the S10e the 66.
    The battery issue
    Under very specific circumstances - that we haven't figured out yet - it might happen that your Lenovo S9/10(e) no longer detects the battery while using S10FanControl or S10Fan. It might occur after 2 minutes, it might occur after 2 months, it might never occur. It does not occur using Notebook Hardware Control.
    It can be solved by removing the battery, waiting 10 seconds and put it back in. Then the battery is re-initialized and the detection works again.
    S10FanControl - Windows
    The first utility is S10FanControl created by user dresslerc. The current version is 1.0.0.1, available here: http://www.mediafire.com/file/yd5xmnrnijf/S10FanCt​rl1.0.0.1.zip. After you've downloaded it you just have to extract it and start the .EXE in the "Release" folder. Here are the notes and the description dresslerc posted right here:
    Everyone,
    I've uploaded a version which everyone can use to test with.  Remember this is still a TEST version although I think it works for the most part.  It should work both on the S10/S10e.
    Please install the .NET Framework 2.0 or later first.
    Then click here to download the exe:  http://www.mediafire.com/?jlg2enkjdxn
    Once downloaded, extract the files and hit hte S10FanCtrl.Exe.  Once this program launches you should be able to control the fan.  Keep in mind that if you lower the fan speed then it'll take upto 30 seconds before the S10 registers the change, so be patient.
    I've only tested this on the latest BIOS 59.  I am sure it will work on the 57 as well but the individual speeds might not work properly on that version.  Please try it out and report back.
    The only issue that I heard so far is that occasionally the fan will kick in regardless if in Manual/Smart Mode.  Also the temp it shows may not be accurate.  If you find any other issues please let me know what they are so I can attempt to fix them.
    Once we have all the kinks worked out then I will release the source. 
    Heres a quick Video:  http://www.youtube.com/watch?v=_PKl70ZgmFg 
    REMEMBER: USE PROGRAM AT YOUR OWN RISK!!! I AM NOT RESPONSIBLE FOR ANY DAMAGES THIS PROGRAM MIGHT CAUSE.
    Application Use:
    BIOS Controlled - Fan is controlled by the BIOS
    Smart Mode - Fan is controlled based on the conifguration in the options.  You can set the threshold here at what temp you want the fan to kick in...
    Manual - Fan is controlled manually by the slider.
    If you want to have the program startup automatically, then place a shortcut of the app in the PROGRAM FILES -> STARTUP folder.  Then you may want to go to the options and make the application minimize at startup.
    Edit:
    It seems there are some issues with the app and the S10e or previous BIOS versions.  Will post a fix asap.
    The source code for S10FanControl is available here: http://www.mediafire.com/?sharekey=7a3fb99d33817c0​8c2b435915e8821d7e04e75f6e8ebb871, written in Visual Basic .NET 2008.
    S10Fan - Windows
    The second utility is a tool written by user slash:
    Hi guys,
    Well it looks like Lenovo dropped this matter after all. Anyway, I have here another fan controller to add to the bunch. I have been using it for some time now without any problems. It is for both S10 and S10e.
    What the program does is basically the same as others. The S10's fan speed is controlled according to the ACPI thermal zone temperature. By over writing the values which resides at offset 50h of the EC register at an appropriate timing, the ACPI thermal zone temperature is over ridden. The program is written in C and uses WinIo created by Sysinternals. The GUI version is available now.
    It should be noted that the fan speed temperature thresholds differs with BIOS version. For 14CN67WW and 14CW90WW  the fan changes speed at temperatures 60c, 65c, 70c, and 80c. Furthermore, the BIOS will automatically shutdown the S10 if the temperature reaches 90c.
    The program has a fail safe mechanism that automatically disables itself if the actual ACPI thermal zone temperature goes above 85c. This allows the BIOS to regain control and the fan will work as intended by Lenovo. If the temperature drops below 85c the program will take over control again.
    To run the program, you will need administrative privileges.
    Known working BIOS versions:  14cn58ww,  14cn60ww, 14cn67ww, 14cn90ww
    The program will work with any BIOS version as long as the BIOS uses the 50h EC register readouts to control the fan.
    build 2009.05.24
    Higher priorities for EC commands.
    Usage: The program will run in the system tray. Double click or right click and use the menu to open the program. To determine the BIOS temperature thresholds, use the 'Setup' button. To run at boot time, place a short cut in the startup folder.

    Notebook Hardware Control - Windows
    The third utility is a profile for Notebook Hardware Control. I've adapted it from a profile for the Lenovo N500 which I've found here: http://nhc.yourcopy.de/overview/. With the manual for creating the profiles that can be found here: http://www.notebook-treff.de/board/database/hilfsp​rogramme-f%C3%BCr-nhc/92-how-to-create-an-acpi-fil​... I was able to change the ACPI commands to work on the S10(e).
    Installation and setup is divided in two steps. The program Notebook Hardware Control (NHC) is available at http://www.pbus-167.com/. Install the program, but do not start it for now. Then you need my NHCConfig utility, available here: http://forum.eeepcnews.de/download/file.php?id=147​6. It detects your model number and BIOS-version via WMI and writes a proper S10(e) profile to the NHC acpi directory. The GUI is German if you have a German Windows and English if not. Additional languages can be added.
    After you've extracted the ZIP-file you have to start the nhcc.exe (requires .NET Framework 2.0). At first a message appears that you use the program at your own risk. Then you can choose if you want to apply your own settings (experts) or if you just want the program to run with my defaults (newbies). In the settings window you can see your system details on the left, you can set up your thresholds in the middle and you can set the fan speed you want on the right. Then click on execute. 
    Now start NHC. Go to the "Settings" tab and click on "Show all NHC options and settings". Then a few more tabs appear. Go to the "ACPI" tab and check if the "ACPI Control System" is running (if everything works, the message "ACPI Control System running" will appear, otherwise it says "ACPI control system is not yet configured for this system"). Now click on "Show ACPI Control System details".
    Here you can change the temperature values the fan control depends on (the settings from NHCC are the default values). On the bottom of the window you can see the "Current CPU temperature". That is the value you have to deal with. In general it has a value of around 60°C. In the middle you can see four user editable temperature values. You can leave the values as they are if everything works. The on/off values are responsible for the temperatures at which the fan starts running and stops again after cooling the device. The level values are responsible for the fan speed, for example you can set the off_level higher to let the fan run all the time at the lowest level, if the values do not fit for your device or whatever.
    You can switch between NHC and BIOS control by disabling or enabling the "ACPI Control System" or by closing NHC.
    Q:
    A:
    With every utility it is possible that it takes some time until you see an effect after you've started the program. Any failure of the programs should be no big problem because the only thing that should happen is that the BIOS controls the fan. Another issue that might occur due to the way the fan is controlled is that the fan may start running for a very short time and it looks like the fan control has lost control. The fan should stop immediately or at least after a few seconds.
    Keep in mind that running the S10(e) with a fan control means that the S10(e) has to deal with higher temperatures. That could mean that the device will not last for 10 years but only 9 years (who uses a netbook so long...?). In every case you need a tool for monitoring your cpu temperature. We know that especially Core Temp 0.99.5 and Real Temp 3.00 do a very good job. That is important because the temperature values you need to set up the fan control are different from the values reported by the cpu sensor, they are between 15°C and 20°C higher. A normal temperature reported by the monitoring should be around 40°C, with the NHC default values the fan starts running at 52°C and stops at 38°C.

    END using fan control
    BEGINNING developing fan control
    Controlling the S10(e)'s fan is a litte bit difficult because it looks like there is no way to control it directly. But it is possible to manipulate the temperature the BIOS fan control depends on. As long as the built-in fan control thinks that the cpu is cool enough the fan stays off. And that is exactly the point where we can attack.
    The fan control depends on a field called RTMP in the memory of the embedded controller. It can be accessed via "_SB.PCI0.LPCB.EC0.ERAM", the offset of RTMP is 0x50 (hex) or 80 (dec). It is a direct I/O read/write. The complete NHC command for reading the value is: ACPI.FIELD.ReadByOffset("_SB.PCI0.LPCB.EC0.ERAM", ref value, 0x50, 8) with "value" as the variable which gets the value.
    What program logic do you need? You need a timer or something else that conducts an always-refresh cycle. It sounds very easy: You read the value, manipulate it and write it back. And it is that easy, you just have to keep some things in mind.
    This refresh has to be done very often. The procedure must be very thin and quick. Also the bus that is used to communicate with the EC is a problem, but since the S10e BIOS 66 it became a minor problem for me because it looks like the built-in fan control now depends on some kind of average value over the last few seconds and it doesn't really matter if one write-cycle is failing.
    The read-event must be placed before the write-event. Otherwise you just read your manipulated value. The field is filled by the system regularly, so you just have to test if the read_value is different from the written_value, then you know that the field was filled with a "fresh" value. Like "if read_temperatue <> written_temperature then real_cpu_temperature = read_temperature else do nothing".
    About the values you have to write back... you will have to test and play a bit. My experience is that you can select three fan levels, starting at 59°, 62° and 70° - at least with the NHC profile and my S10e it's like that. It's some trial 'n' error. My fan stays off at < 59°, but you should select a very low value for fan_off like 30°. In my opinion it switches off much faster the lower the written value is. But it's just a feeling, I haven't measured it.

    Great opening post Carsten!
    The latest bios:
    http://www-307.ibm.com/pc/support/site.wss/documen​t.do?sitestyle=lenovo&lndocid=MIGR-71252 (BIOS 66)
    The FSB can be reduced from 133MHz to 100MHz using SetFSB, this also reduces the heat:
    http://www13.plala.or.jp/setfsb/
    clockgen = SLG8SP513V
    If you add a shortcut to the startup folder the program will start at startup. Under properties you can change the target to:
    "C:\Program Files\SetFSB\setfsb.exe" -s100 -b1 -cg[SLG8SP513V] -w20
    So it starts with a FSB of 100Mhz, in the background, with the right clock generator, after 20 seconds.

  • Enabling system fan control on lenovo s30

    Hi there, i am familiar with the BIOS setup for fan control, except, i do not know how to load a "user profile" vs factory default. Does S30 even support user fan control, my d20 would allow me to select several presets, however, the s30 bios only allows two options one of them being user preset? How do i load this preset (i want the fans running at higher rpm for additional cooling). Any insight is appreciated.

    There are a few differences in the fan control design between 20 series and 30 series.  In 20 series, you're correct that there were a couple of selectable presets available.  For 30 series, we took a different approach where the fan speed control was set to a standard profile for all users.  We did, however, have the ability for our BIOS team to create unique fan tables that would be meant for specific customer environments.  The only way to use one of these custom tables would be to work directly with our BIOS team as each table would need to be manually created.  So custom tables are not supported for general field use.  
    We chose that route on 30 series because a very large majority of our customers never changed the default fan settings (the thermals on 20 series were so good they rarely had a reason to do so).  
    Is there a specific reason you want to change the fan control, or is this just a tinkering-type question?

  • Fan control in notebooks

    Hi all,
    I am using Arch Linux since a few months, right after purchasing my new laptop, a Dell Precision M3800. Anyway I am a linux user since many years. I like very much the control that arch give to the user in terms of configuration possibility. My question is relate to fan control in notebooks. Even though I noticed this issue in my laptop now, I think similar observation holds also for other notebooks and linux distros. For fan control I use the fancontrol utility. Once properly configured, there is a min temperature value below which the cpu fan is off (default is 20 °C, I increased up to 45 °C) and a max temperature value (default is 55 °C and I placed 65 °C) above which the fan is running at full speed. The reason for the temperature limit changes is to emulate windows behavior in terms of noise and thermal handling. With a room temperature in the order of 25 °C, I get right after login a cpu temperature of about 35 °C. Then the temperature increases even in idle conditions up to the limit of 45 °C and then it is stabilized by the cpu fan. Chaning the temperature between 35 °C and 45 °C simply changes the time interval I have to wait until the cpu fan switches on and cpu temperature stabilizes with low load. The point is the the stable thermal situation produces a continuous switching of the fan state, let's say the fan is on for a few seconds every minute. The reason is that the fan switches off right after the cpu temperature falls below the value for which it turns on. Wouldn't be better to define two different temperatures for switching on and off? Let's say, fan on when temperature reaches 45 °C and off when it falls below 40 °C. Is there a way to do that with fancontrol or same other tool?
    Thank you in advance.
    Bye,
    Luca

    OP, what you're describing is called (at least in HVAC circles) hysteresis.  You may be able to find some fan control scripts that support it (googling fan control + hysteresis), or just write one yourself.  You can also control this behavior to some extent by adjusting fancontrol's polling behavior (the "INTERVAL" setting), but that has risks. 
    I think implementing hysteresis is not a particularly useful endeavor because PC temperatures can change 30 degrees or more in a few seconds when under load, which is completely unlike, say, a home thermostat where temp changes are much more gradual over time.  Realistically, you should expect to always be running at least the CPU fan at some speed, and set your "turn off" temperature for it to room temperature.  You can set different temperature set points for different fans, so you can have the CPU fan turning off at a lower temp, but have other fans off until the temp gets much higher.

  • SMFC Fan control

    I installed the SMFC fan control app to cool down my rmbp but im now paranoide about the defult settings so i deleted the program and shut down my mac and turned it on again hoping it's now at it's defult values... So i thought i'd reset the SMC too, does this make the fan speed defult again by resetting the SMC?

    smcFanControl may damage your Mac if you set up a very high fan speed for a long time. If not, it doesn't have to damage anything.
    I don't know the default fan speed for the MacBook Pro with Retina display, but 2000 rpm is a too high fan speed

  • Fan control questions

    Hi
    I have a mid 2008 2.8Ghz iMac with the stock 320 Gb HD and 4 Gb ram. It runs fine but I am worried about how hot the case gets at times, in particular the top left corner. I have iStat widget installed too which shows what I think are reasonable temps most of the time, but sometimes even after just everyday use (browsing etc...) some of the temps seem high (power supply is presently at 75c). The fan speeds don't seem to increase much at all from the factory minimums. I know about smc fan control and iMac fan control, but I have a couple of questions before I decide to use them.
    1. Do you think I need to be worried about this?
    2. What damage could I cause by running the fans harder?
    3. If I use these utilities to push the fans harder than Apple recommends, will I void my Apple Care?
    Looking forward to your answers
    Paul

    An utility like smcFanControl only changes the minimum fan speed setting. You are still running the fans well below its maximum capability. So the change is to the low end of the speed range, not the high end. You CAN set it high enough so that the minimum fan speed sounds like a small vacuum cleaner, but I would not set it that way for any length of time. I just tried it once to see what it sounded like with the fans running at a high speed (never heard them before). There is a max possible setting, so you can't set it to a crazy high number.
    I use smcFanControl and have the fans set about 25% higher than the default speed. I still can't even hear them at that setting, so I figured I wasn't doing any harm and it may help my iMac run cooler (not that noticed any issues with heat).
    I can't see how it would void AppleCare. Unless you set it to sound like a vacuum cleaner all the time (which would be really annoying), you are running the fans well within their normal operating range.
    Note: The adjusted minimum fan speed is only in effect while smcFanControl is running in the background. It does not change any system or hardware settings. To go back to the default settings, just quit smcFanControl.

  • Fan control reset

    hi how are you all i installed fan control and i forgot whats the factory fan settings as i have played around with it as aim a newbe to osx i have a macbook pro 13 i5 it wuold be great help if someone told the def seetings thank you

    "remove the fan control program you installed."
    And then reset the SMC, which will restore the default fan settings, in case simply removing Fan Control doesn't do it.

  • Fan Control Apps for MacPro 2.93 Mhz ....

    Ok, I figured out how to disable Fan Control.
    Now I only have smcFanControl installed. I can hear the fans running all the time now. Before I installed FanControl and smcFanControl I could rarely ever hear the fans, even during the hot summer.
    I have the slider controls set to the minimum, but the fans still run constantly, and my room is in the 50s F.
    I really don't think the fans should be running all the time. The only way I can find to stop this, is to delete smcFanControl.
    Is there any other FanControl apps that will allow you to adjust the fan speeds so the fans will not run all the time?

    the fans are suppose to and need to run.... all the time.
    but normal default is 499/599 rpm
    boosting the minimum default is useful
    you can have and should have profiles for low-medium-high if you push and use your system heavily
    sounds like you have
    too many cooks - spoils the soup
    corrupt preference file
    are not using the SmcFanControl for intended purpose and as designed
    most people do create multiple sets and have "my default' (for want of a name) @ 800-900 which improves air flow and thermal temps while still being quiet.
    older FBDIMMs are HOT and helps keep them in the 60's *C or if you have a hot GPU and need more air flow
    maybe you have dust or other issues or the Mac  Pro is recycling its own hot exhaust
    The thing to look at is WHAT is (hardware) Monitor showing for your TEMPS from the thermal sensors as to what is or is not normal
    And reset the SMC / and delete the plist files used
    Never use more than one background utilty for a job and keep all of such utilities to a MINIMUM for best fastest stable and for performance, they do add up, they do matter. "Less is more."

  • Is it bad to use Fan Control?

    So I was looking into running Boinc (donating CPU time to run science projects aka grid computing) on my computer and installed Fan Control so I turn up my fans to keep to comp cooler. I have hence been convinced that it isn't the best idea to run your CPU so high on an MBP since I didn't want to wear out the fan and/or damage any hardware near the CPU. I still have Fan Control installed. Is this okay? I have heard mixed things about manually controlling fan speeds? Should I go to the trouble of uninstalling, or can I just leave it on low settings? What settings should I put it on?
    Thanks for all of your help!
    And a shout out to all those students out there: Happy winter break! We made it!

    There really is no need for third-party fan controls. The OS is already configured to increase fan speeds in response to higher operating temperatures. So uninstalling the software is appropriate. However, you need to return the fan configuration to its original setting(s) which is an idle speed of 2000 RPM for each fan (if your model has more than one.) Once you do that you can then uninstall the software using the uninstaller, if it has one. Otherwise, see the following:
    Uninstalling Software: The Basics
    Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
    Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
    Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
    Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
    Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
    If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
    Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
    There are also several shareware utilities that can uninstall applications:
    AppZapper
    Automaton
    Hazel
    CleanApp
    Yank
    SuperPop
    Uninstaller
    Spring Cleaning
    Look for them at VersionTracker or MacUpdate.

  • 290x lightning bios for fan control?

    Hi, would an updated bios fix my 290x Lightning not having manual fan control?
    Serial Number: 602-v307-04sb1403020690
    Here's a link to the bios:
    https : //drive . google . com/file/d/0B0bFt35qm1QVeWNhMW55Nmk2Tk0/edit?usp=sharing
    The forum wouldn't let me post a link, so it has six extra spaces. Apologies.
    Two side questions:
    1) Afterburner (even after a reset) says +63 on voltage. Is that a display error and though it says +63 it's actually at +0 extra, or is it actually just defaulting to +63 right off the bat? So, for example, if I set it to +100 would that actually be giving it +100 or just +37?
    2) With Afterburner no longer being updated for new features, is there an alternative program that is continuing development?
    Thanks!

    For the vios:
    Use the attached UEFI vbios versions to fix the fan issue.
    TV307MH.101 is normal vbios, TV307MH.111 is LN2
    Create a bootable usb stick (https://forum-en.msi.com/index.php?topic=165175.0).
    Then unpack the previously provided archive (307_04s.rar) and put the included file (TV307MH.101 or TV307MH.111) on that stick.
    Rename TV307MH.101 / TV307MH.111 to 101.rom / 111.rom. Put the atiflash.exe also included in the archive on the USB stick too. Now boot from the stick.
    Type atiflash -p -f -noaper 0 101.rom (or 111.rom) [ENTER] and let it flash the vbios.

    It is +63 by deafult (without changing values)? With Normal or LN2 vbios or both? Did anything change with new versions above?

    I'm not aware of what you are talking as Afterburner is under development all the time. The latest version 3.0.0 final has just been released. >>How to use MSI Afterburner<<

  • Is Fan Control Safe for your MacBook Pro?

    Im just wondering if Fan Control is safe for your MacBook.
    does anyone here have an experience using it?

    smcFanControl works fine. It won't hurt anything. You can't slow the fans down below the factory default setting.

  • MSI Z77 mpower fan controll

    MB: MSI Z77 MPower
    In bios the auto option is avaliable only for CPUFAN and SYSFAN1 SYSFAN2. At the same time in ControlCenter it is possible to enable System Smart fan controll for each fan.
    Is there any way to save selected options in Controll Center and automaticly apply them on sturtup?

    Hi
    CC shows very first settings taken from BIOS. So whatever its set in BIOS, CC will show this by default. And sadly cannot be changed to be applied differently. Yet you can change settings in BIOS and you should not need to use CC for fan control.
