It would help to know what kind of laptop this is. There are several programs out there that can control the fan on laptops, but not knowing what you have, I can't research the right application for you to use. There isn't an app that I know of that will "speed up" your fan though. And, its more likely you're seeing these high temps because the laptop is running "full speed" all the time. If you go to power options, you should be able to set the laptop to run with "dynamic switching" while on both battery and AC. This will help to minimize battery usage, and also help bring down the temperature.
Laptop specs please.
