1st off I would suggest following Mayer's advice. His advice is the correct and safe way to solve your problem. If that is not possible, no, replacing the logic board is not the ONLY solution. Using a "program" to adjust the fan speed may be a solution, although it still may cause still kernal panics or other problems. All these sensors talk together and communicate with the SMC. There is a risk of causing further problems by not doing things "the Apple way". There could be more than one issue causing the fault code, the fault codes are derived by a triangulation of multiple sensors. Sometimes a faulty temperature "error code" can actually be caused by an incorrect voltage reading on another part of the board and/or other things. Try a program that corrects the fan speed and monitor your system logs. Let us know the result. Information helps us, help others, at this point you are one of the others.
