Default Lower Video Card noise by reducing the fan speed

Modern video cards come in two flavors. The noisy ones that have lots of horsepower and the silent ones that trade some of the horsepower for a reduced noise level. This is currently changing with the release of the Nvidia Geforce 8600GT but most users have an older video card in their computer.
My 6600 GT was making lots of noises that were driving me crazy. I could not understand why it was necessary to run the fan in full speed when writing a blog post like this. I was able to reduce the fan speed using the software Rivatuner which has fan profiles for 2D, low power 3D and 3D modes.
Reducing the fan speed is not possible for every video card. I had to update the bios of my last video card to be able to reduce the fan speed. My suggestion is to load Rivatuner and see if you can change the fan speeds to reduce the noise of your video card. Here is how you do that:
Begin by downloading and installing Rivatuner. Once that is done run the software, you will see the following screen.
Click on Customize in the Driver settings block. A overlay menu should appear with several icons, click on the first entitled System Settings. This will load another menu with several tabs. The second tab is called Fan and that is where you can reduce the fan speed for the different modes.
I suggest to play around with the settings a little bit. I would leave the performance 3D setting at 100% and reduce the other two settings. In my case I have given them the values 40% and 50% respectively. Make sure that you monitor temperatures of your video card when applying this settings. You have to make sure that it is running stable with this reduced fan speeds.
Click on Apply fan settings at Windows startup. This ensures that fan speed will be reduced during Windows startup to lower the noise when working with Windows.
Rivatuner has an option to monitor the temperature of the video card. Click on ok to leave that menu so that you see the main menu again. Click the Customize link at the Target Adapter setting and select Hardware Monitoring from the list. Now click on the red dot in the left bottom corner. This starts hardware monitoring and will report the temperature of the video card if it has a thermal diode.
