Try resetting the SMC and PRAM on this thing. It might help you

To to the PRAM, shut the computer down press the Command, Cption P and R keys all at the same time then turn the computer on. From this point it eill restart and bong again. I would do this 2-3 times to make sure it sticks. Once it's done let the keys go.

To reset the SMC, follow this from Apple. If this doesn't work it's a sensor issue. You'll need to do surgery on the laptop. I'd go to a Apple store and get ASD run on it to see what it needs to fix the problem. Apple doesn't exactly give ASD out but people do find it. I don't want to link to a source I know has it because Apple will probably send a team of lawyers after me :-(

If it's a fan sensor just use SMCFanControl until you can get the part replaced.
