RivaTuner is a freeware tweak utility for NVIDIA and ATI based video cards. I have been using RivaTuner for a while to reduce the fan speed of my video card to decrease the noise level. I configured it to decrease the fan speed to 25% in 2D mode which includes all applications such as word processing and internet surfing. This is the lowest setting that is possible and it did reduce the fan speed so that the video card is almost silent.
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 Refreshrate to AGP transfer rate, everything seems to be at place and accessible if you need to tweak a certain value.

my laptop overheats causing the fan to rev up a lot when i m downloading with bittorrent…do you think riva tuner might help?
I don’t think that this will help because it is only possible to slow down the fan. I suppose it has nothing to do with your video card but with the hard drive which overheats.
i know it’s off topic (sorry) but any suggestions on how to cool the hard drive
