Did you clean off the old thermal compound and reapply new thermal compound correctly? I had a G53jw that was similar and it ended up having a bare spot on the cpu (bad paste from the factory). Overtime the bare spot must have gotten bigger and to the point where it would run the fan 100% and shut down the laptop.
If it's a temp sensor for the cpu that's the culprit, then it's probably built into the cpu and can only be repaired by replacing the cpu.
If I were you I would buy a cheap cpu of the same socket to see if the fans behave as normal. If they don't return to normal then there's probably a small component on the motherboard that's out of spec or burned out.
