A rule of thumb is that MSI Afterburner supports most Geforce and Radeon cards providing that the drivers installed are not to old. Try updating the drivers if the video card is not recognized by the software immediately.

MSI Afterburner is based on Rivatuner, another popular video card configuration software. The program displays a hardware monitor and core information about the graphic card on startup.

The core information include the graphics card name and driver version as well as the core voltage, core clock, shader clock, memory clock and fan speed. The availability of these values depends largely on the graphics card itself, if it is supported it should be shown.

Sliders are available to change these core parameters directly. The hardware monitor on the right side displays max and min values. These again depend largely on the capabilities of the video card. It is for instance possible to see the graphics card maximum and minimum temperature, fan speed and core clock changes.

Settings can directly be saved in profiles. This is handy for overclocking or underclocking the graphics card in specific situations. It is for example possible to create one standard profile, one overclocked profile for gaming and other gpu intensive tasks and one underclocked profile for situations where the graphics card is not needed at all.

The settings button leads to an extensive configuration menu. Here it is possible to change the behavior of the card’s fan, the hardware monitoring, on-screen display and profiles among other options.

Fan Speed

The fan speed controls can be changed from automatic to user defined. This opens a graph where the fan speed can be adjusted to the temperature of the graphics card. The fan speed could for instance be lowered if the gpu temperature is low and increased if it increases.

Hardware Monitoring

Hardware monitoring graphs can be enabled or disabled in this tab. It is furthermore possible to activate hardware monitoring history logging which can be helpful when troubleshooting video card problems.

Hotkeys can be assigned to the profiles that have been created to switch easily between them. There is also an option to set automatic 2D and 3D profiles which will then be automatically enabled whenever the system uses 2D and 3D applications (meaning gpu-less and gpu intensive processes).

An onscreen display can be configured in the MSI Afterburner software to display relevant information directly. This – and some other settings – require a server process that needs to be running in the background.

Computer users with multiple gpus can configure the clock, voltage and fan speed individually or in sync.

MSI Afterburner is an interesting tool for users who want to tweak their graphics card. The program is compatible with 32-bit and 64-bit editions of Windows XP, Windows Vista and Windows 7. Downloads are available directly at the MSI website.

The guide will walk you through creating a 2D and 3D video card profile that will automatically switch the fan speed and the clock speeds of the video card depending on the application that is running on the computer. This generally means low clock and fan speeds in 2D mode and normal (or even faster) clock and fan speeds in 3D mode.

The program that can do all of that is called Rivatuner. It is compatible with both ATI and NVIDIA video cards. The advantage of using Rivatuner is that the software can do everything that we need and works both in 32-bit and 64-bit editions of Windows XP and Windows Vista.

Please note that the clock and fan speeds are valid for the Geforce 8800 GTS video card that was used in the test and that the values for other video cards might differ. There is however a general pattern to it which will be explained.

1. We are going to create the following two profiles:

2D Mode: Low Fan Speed, Low Core Clock, Low Memory Clock
3D Mode: Fan Speed that cools the video card sufficiently, Default Core Clock and Memory Clock speeds. Advanced users could overclock if they like.

2. Configuring Settings:

Before we can start to apply the profiles we need to make sure that we can set the clock speeds and fan speeds to lower values in 2D modes. This is done by clicking on the Power User tab and locating the following entries:

RivaTuner \Overclocking \Global

• MaxClockLimit: 200
• MinClockLimit: 15

RivaTuner \Fan

• MinFanSpeedlimit: 10

The first two values in Overclocking \Global enable a wider range of clock speeds that can be configured in Rivatuner while the second sets the minimum fan speed of the video card fan to 10%. The default without that setting would be 25%. Restart Rivatuner afterwards so that the changes can take effect.

3. Configuring core and memory clock profiles for 2D and 3D modes

Open the System Settings menu of Rivatuner by clicking on the icon next to customize next to Driver Settings in the lower half of the main window and selecting the leftmost icon in the appearing icon pane.

The System Tweaks window will show up displaying Core, Shader and Memory clock speeds. The first profile will be the 2D mode. Remember that we need low settings for core and memory clock in that mode which will save power, reduce video card temperature and allows to reduce the fan speed because of this. The effect is a power saving, low temperature and low noise profile.

The value depends on a few factors and it is probably a good idea to start with relatively high clock speeds and reduce them further if no problems are experienced. A minimum core and memory clock of between 200 to 250 should be the goal for the 2D profile.

After setting the clock speeds check the Apply Overclocking At Windows Startup box. Hit Apply at the bottom and save the profile under Overclocking Profile Settings. (2D Profile)

Now do the same for the 3D clock speeds. A click on Defaults will load the default speeds for the video card. Make sure the Startup Settings box is unchecked. Click Apply again and save the profile. (3D Profile)

4. Configuring the fan speeds for the two profiles

After creating the two clock speed profiles for 2D and 3D mode we have to create a fan profile for each mode. The fan setting can be loaded by clicking on the icon next to Customize under the Target Adapter area of the main interface and selecting the first icon of the icon row called Low-Level System Settings.

We start by defining the fan speed for the 2D profile. A click on Enable low-level fan control will provide access to the fan speed settings. Select Fixed from the check boxes and move the slider to the left. Clicking Apply will change the fan speed to the selected value. It’s a matter of listening to the fan and selecting a fan speed level that is barely, if at all, audible. A value between 10-20% should be perfect for most video cards and ears. You should not set it to low unless you keep an eye on the temperature levels of the video card.

Check the Apply Fan Settings At Windows Startup box, hit apply and save the profile. (2D Fan).

Now do the same for the 3D profile. A click on Defaults will load the fan speed defaults again. Select a Fixed fan speed value that you are comfortable with, apply the changes and save the profile. (3D Fan)

5. Monitoring System Settings That Reveal 2D or 3D mode

We have created two clock speed and fan speed profiles and set the low clock and low fan speed profiles to load at Windows startup. If you keep the settings this way the 2D settings will be loaded in 3D mode because Rivatuner does not know when to change the profiles. You would have to change them manually whenever switching from 2D to 3D or vice verse.

What we do know is to configure hardware monitoring which will give the profile launcher the information needed to change profiles automatically.

Hardware monitoring is another icon in the Target Adapter icon row that appears when clicking on the icon next to Customize. The Hardware Monitoring display will open. A click on Setup in the lower right corner opens the settings which allow us to define additional values that should be monitored.

There are a few options to distinguish between 2D and 3D mode. One is to monitor Hardware Acceleration which is unfortunately also triggered in some 2D applications. A hardware acceleration of 0 means that it is off and would trigger 2D mode while a hardware acceleration of 1 would mean it is turned on and would trigger 3D mode. Another option is to monitor the Framerate instead which is always 0 in 2D mode.

You can enable one or both settings in the Data Sources menu in the lower half of the menu. A click on the checkmark in front of the name of the source will activate the monitoring of the source. A click on OK will close the setup window. Now find the Hardware Acceleration graph in the Hardware Monitoring window.

An icon is displayed next to the Hardware Acceleration name. A click on it will check the hardware acceleration continuously. A new icon will appear in the system tray. Right-click that icon, select Setup and check the Run At Windows Startup entry. Now that we have done that it is time to configure the profile switcher.

6. Configuring the Profile Switcher

Before we can schedule the profile changes we have to create two launcher items. Selecting Laucher from the main tab and clicking on the green + icon will initiate that. Select Regular item from the next menu.

Enter a name (2D / 3D) and check the Associated overlocking profile and Associated fan profile boxes. Select the corresponding profiles created earlier. You should have a 2D and a 3D launcher item afterwards in the main Launcher window.

Now it is finally time to configure the Scheduler. A click on the Scheduler will load a window that resembles the Launcher tab. A click on the green + will open the menu were we can configure when to change from the 2D profile to the 3D profile.

Give the task a name, select the 3D profile from the list of profiles under Name and select Run Task on hardware monitoring range event under Schedule. Pick Hardware Acceleration as the Data Source and select a range from 1 to 1. A click on OK will save the new scheduled event.

Now create another scheduled event for automatically switching from the 3D profile to the 2D profile. All settings remain the same except for the profile which obviously has to be the 2D profile and the range for the hardware acceleration setting which has to be 0 in both cases.

Conclusion:

We have created two profiles which switch automatically from 2D to 3D and 3D to 2D profiles. The 2D profile will make use of a low noise fan, low power consumption and lower temperatures while the 3D mode will use the default video card settings to ensure that all 3D applications function properly with decent framerates.

If you have any questions about the procedure feel free to ask. Please note that Rivatuner will automatically start with Windows when setting this up this way.

Once a 3D application is started the fan starts spinning faster to be able to cool the video card. RivaTuner users may use several other settings in the program to overclock their video card or create custom settings for certain applications. I’m personally using it only to reduce the fan speed but hardcore gamers who need every fps they can get will find the overclocking settings as useful.

To be honest, I did not check all the settings that you may alter in detail but it looks really complex and complete. From refresh rate to AGP transfer rate, everything seems to be at place and accessible if you need to tweak a certain value.

A guy suggested to use the freeware RivaTuner which he said was able to reduce the fan speed of my video card by altering the fan speed directly. This was the solution I was looking for. I quickly downloaded and installed Rivatuner. The only thing left was to lower the fan speed and make the changes permanent.

I clicked on customize in the first screen that appeared right next to Forceware detected and selected the icon for system settings from the panel. The second tab was named fan, the goal of my search. I was able to define a fan speed value for three different states: standard 2D, low power 3D and performance 3D. I changed the settings from 100% to 25 in standard 2D mode, 50% for low power 3D and 100% for performance 3D. 2D means everything that you do normally in windows like using office, surfing the internet or writing an email.

I checked the box that saved the settings and applied them at every system start and voila – the noise was gone. From one second to the next it was gone. My pc is almost silent now, the noisiest part is my external hard drive, everything else is almost silently. (I bought a low noise cpu fan and power supply).

I suggest you take a look at Rivatuner if you face a similar problem like I did. It might solve yours too
