Temp/Fan Control

My blackbooks temp hits about a high temp of 190 degrees F. Of course this is when it has been running for a few hours. Is this bad or normal? I installed an SMC fan control utility and it allows for optimal fan usage. Would you reccomend it?

Hi,
I'll be getting my 1st Macbook in about a week, but I have had a few laptops in my time.
They all run hot when they are being used. I ended up buying myself a Laptop Cooling Stand. You sit your laptop on them and they have 1-3 fans running to cool your laptop. They work great.
A computer Tech, told me to always use a laptop fan as this extends the life of the laptop.
iBreeze make a cooling stand, its on a slant for your laptop. Plus as they are USB run, it has a passthrough USB port so you don't loose a port when using the fan, like other fans.
I hope this helps.

User-developed 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.id=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/S10FanCtrl1.0.0.1.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=7a3fb99d33817c08c2b435915e8821d7e04e75f6e8ebb871, 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/hilfsprogramme-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=1476. 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/document.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.

848P Neo-LS Fan Control

As said - no control of the damn fans (Case/CPU) on my 848P Neo-LS. On the CoreCenter the button lits up on mouseover, but when pressed, nothin' happens (as said in manual, press to toggle user/auto modes for fan control).
Also CoreCenter doesn't show the Case fan's speed, but Northbridge (NB fan) fan's speed, which is obviously 0. Also NB temp is N/A. Also +12V is N/A. Also the FSB stays always at 101 Mhz, not 100. No overclocking done.
Today upgraded the CoreCenter to the most recent vers (1.7.0.0.), and the button doesn't lit up anymore...?
When I installed SpeedFan 4.17, it allows me to control the Case fan's speed from 2300 - 2700, but nothing more. Interesting.
CPU - Celeron 2.0
RAM - 256 MB Kingston
CPU Fan - OEM intel fan A80856-003
Case Fan - MJ 802512
Both fans with speed sensors, of course.
Should I update the bios?
Help somebody!

To be sure I opened the case and stopped the fans by hand (I don't use the corecenter prg - piece of crap), to see that i have mistaken both fans (in SpeedFan prg). The one who varies by 400 rpm is the Cpu fan.
Doooh.
The bios health screen doesn't show +12V at all - just aint there...
The MSI tech support sez - flash the bios, and if anything doesnt change, the CoreCell chip has gone (faulty, whatever).
Flashed the bios (1.0 - 1.9 now). No changes.

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.

IStat Pro, SMC fan control and tempuratures

I've been watching the recent temp. problem threads with great interest.
My Imac has had no operational flaws *knock wood* but I'm a bit concerned with the temps which iStat Pro is reporting. For instance;
CPU A 103 F.
CPU diode 133 F.
Ambient 79 F.
Memory Control 112 F.
HD Bay 1 103 F.
Optical Drive 94 F.
WDC WD1600 etc etc, (the hard drive I presume), 99 F.
Most of these temps seem pretty darned high to me. OR, am I mistaken and they are not out of line?
Running SMC fan control at about 1/2 way up on all 3 sliders brings these temps down considerably, but I hate to "over rev" the fans and hasten their demise if I don't have to.
I'll appreciate your thoughts.
Thanks; Jon

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.

Extended fan control v.1.2

Can anyone tell me why this version of fan control does not detect sensors on the GPU despite having an apparent facility to do so? The temp for the GPU always reads zero degrees, which suggests it's not picking it up. As my macbook pro overheats when the capture window is open and working, I presume a lot of the heat is being generated by the GPU, so it would be useful to monitor and fan-control it.
Nick

Not all MBP models are supported. You'd better check with the maker of EFC:
http://www.derman.com/Download/Special/MBpFanControl.html
But he'll probably tell you to get the source code and do the necessary modifications yourself.

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 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."

Dell Vostro 3560 CPU Fan Control Tips

I'm in the process of configuring my brand new Vostro 3560 and one of the things I noticed was that the CPU fan was blasting full speed all the time even when the machine was idle. After some researching I came up with the following solution using i8kmon and I'll post it here for others:
Disclaimer 1: In this configuration, you will be setting up thresholds on what fan speeds are used at a specific temperature. If you use this config, this assumes that your machine is a) reporting the correct temperature and b) the fan speed setting works for your specs. Always monitor your laptop and change the configuration if your laptop feels too hot.
Disclaimer 2: I've only had this laptop for a couple of days now, so no long-term stress testing has been performed in this configuration.
This is a link that helped me a lot. It's Ubuntu specific, so be aware of the differences: https://answers.launchpad.net/ubuntu/+s … ion/204193.

/usr/lib/systemd/system/i8kmon.service
from
[Service]
ExecStart=/usr/bin/i8kmon -nd
to
[Service]
ExecStart=/usr/bin/i8kmon --daemon --nouserconfig

Dell Vostro 3560 no automatic fan control

Hello,
I own this laptop and i am able to set the fan speed via
This shuts down the fan.
i8kfan -1 0
This make the fan go on full blow.
i8kfan -1 2

This:

Keeps running, but the fan is on full blow no matter what.
I have added this service to systemd and it gets loaded okay,
but it runs the i8kmon --daemon, which does nothing.
Any hints?
Thanks

I have a dell vostro 1710, no fan running at all!
I have opened it, and saw it spinning for a while on notebook power on, so it looks like it works
Do not remember if this is happening a long time ago, or maybe after a Syu... but now temp is on 62 doing stuff, 74 watching a video..... it will be more than 80 in summer? lol
Will install and configure i8kutils I guess....

Is anyone using SMC fan control on their late 2009 iMacs?

I am very concerned about the heat from my iMac.
I have a late 2009 27 inch model.
I noticed a lot of posts of GPU and HD failures.
I bought this iMac used through a certified Apple reseller and I can't afford any problems with this for awhile.
Computer components do not Ike heat.
And despite everything I have been reading in this forum aluminum can retain heat. Not simply vent all of it away from the back casing.
Excessive heat is what shortens the life span of any components In a computer.
Heat in a computer is the enemy!
I do not care what I am getting for temp readings from my iMac.
It's very, very warm and I don't like it and feel it will cause issues in the near future.
I just bought this iMac three months ago and, at least for awhile due to personal health issues, I can't afford to repair a potential failure that might occur in the near future.
I posted a similar thread not long ago but only got one response I was not happy or confident with.
I want to know if anyone is running SMC Fan Controls on late 2009 iMac models and if it has helped and whether anyone had issues with it.
I want my iMac to run cooler than it does now.
I am in a living situation where I have limited means to cool the place I live. The room I am using has no air conditioning only a large ceiling fan and I am running a floor fan. I have a small fan blowing air behind the iMac's case to help with cooling it, also.
Room temps can get into the high 80's.
Also, if you are running SMC Fan Control on a 2009 iMac, could you give an idea what RPM setting you are using for the various fans.
I am a freelance graphic designer, Illustrator, and audio/video guy. Plus I have doing 3D CGI model work for the last few years. I run Photoshop. Final Cut and Blender quite often.
Any real help with this issue would be greatly appreciated!
ThanX.

Even if I had one, I wouldn't run SMC Fan Control. Apple has not released the limits of temperature for any of its Mac model interiors. As such any temperature management is purely guesswork. If you are having serious trouble maintaining an enivoronment suitable for computers, you probably should consider at minimum a window air conditioner unit. http://www.apple.com/imac/specs.html are very particular about the outside environment. If that is not able to be maintained, you seriously need to consider a different working environment.

Mpower Fan Control

My cpu fans are going at 100percent @1300rpm the whole time, its driving me crazy. Tried to set in down in control centre, no luck. Any way I can set it down to luck 50percent?? thanx

Im not sure phantek fans are true pwm fans, from what i heard they were 3pin with a converter that simulated the pwm signal, then again i might be wrong, as i dont own any phantek fans at all.
Try something, drop the command center and try the bios fan control, on CPU header will be PWM control so you need 4pin pwm fan,
Increase the min temp to 50C (this is just to have a bigger margin to lower the rpms), and put the max in 80C. Now change the min % to 50%, and the max move it to 75%, save the setting on the bios and reboot to BIOS again see if the rpms are lower now, if they are tweak them to what your fans can tolerate or what you can tolerate on noise, i would try another boot on 37.5% if it rpms are lowering, i would try 25%, if the fans stop or dont lower just retun to the last preset you had.
Personally i love MSI bios fan control, but their software imo isnt that good, at least compared to what other offer, but in bios, i love msi.

Z87 Gaming Boards - Questions regarding fan control / soundblaster cinema...

Hello everyone,
I'm thinking about switching to MSI Z87-G45 Gaming (currently using Asus Gene-Z V), however there are three issues that I've been unable to find information on:
1) Fan Control
The new msi boards seem to have new bios fan control which enables you to set a low temperature and corresponding fan speed, aswell as high temperature which marks the temp when the fan will reach 100% speed. However I've read that this is only available for the CPU_FAN1 header and not CASE_FANX or even CPU_FAN2 (if available). Is that true?
2)Audio Solution
The middle boards seem to feature Realtek 1150 in combination with the software solution Soundblaster Cinema (Xpower as X-Fi MB3). Now the soundblaster cinema really confuses me, is it better than the X-FI MB2 (thats the software solution of the asus Z77 rog boards)? Does it have the "soundblaster console" in addition to thx true studio pro or is it just the thx utility etc.?
3) VGA Boost in combination with msi graphics cards
What exactly does this do? It says that it automatically increases the power target, but is that useful if you also use msi afterburner?
Thanks.

Thanks for info, I ordered a G45-Gaming today and let's see how it works out.

Can you control 3 pin fans with this board?
BTW first post here :-)
I can update you on this issue once I get everyone up and running, however generally msi had the following setup:
CPU_FAN headers -> pwm control (and sometimes voltage too)
CASE_FAN headers -> voltage control only (= 3 PIN fan)
The "old" case fan control sucked though since you could only set a range from 60% to 100% on the fans whereas for cpu fans you could set 0 to 100%. Also the minimum temperatur for case fans was 40° which in makes case (case temp never rose above 35°) made case fan control pretty much useless.

Fan control unlocked on the NX6600GT-VTD128

The bios edit that enabled temp monitoring, also enables fan control when you use Gainward ExpertTool.

Why not add that to the original thread?
