Try resetting the PMU. This resets a lot of power-related functions and I've seen it put an end to erratic fan activity.

they don't tend to speed up until you start pushing the CPU and gpu, along with other components. if it gets very hot and the fans stay the same then you might have messed something up, otherwise just typing or searching the web won't heat it up too bad
