Jstervil, The problem is most likely related to the sensor of the Ts0P Palm Rest Temp sensor. The palm rest sensor is located on the hard drive cable. It is under the hard drive and up against the front edge of the machine. It may be a bad sensor or your may after corrosion, liquid spill etc. You may want to consider to download and install this [http://www.tunabellysoftware.com/tgpro/|Temperature Gauge Pro]. It should help show you what your sensors are telling you.

Jstervil, here is my answer from a similar question. The problem is most likely related to the sensor of the optical drive fan. Replacing the sensor and/or the fan should resolve this. Try to start under Safe Boot mode. Follow this Apple TN" [http://support.apple.com/kb/HT1564|OS X: What is Safe Boot, Safe Mode?]. Download and install this [http://www.tunabellysoftware.com/tgpro/|Temperature Gauge Pro]. It should help show you what your sensors are telling you. Make sure that your fan is functioning, you can try to push the fan back onto the motor and see if that works. If not, replace it.
