I have rivatuner 2.21 and when i go to the screen in which there should be a tab that says fans there it not... I don't know why. Perhaps someone can shed some light on this for me thanks...
Mobile GPUs aren't officially supported in Rivatuner. If your laptop has an Nvidia chipset then try nTune, if it has an Intel chipset you might want to give Speedfan a go.
