Apple MacBook Pro “Core 2 Duo” 2.6 17" Is it possible to replace the thermal sensor that’s attached to the heat sink? Or do I have to replace the entire heat sink?

Lets try this first. If you have your system put back together can you download this fan & sensor monitoring app: Temperature Gauge Pro. There are others I just like this one. The free trial version should be enough for now. Post a screenshot of what it shows for us to see. Your problem maybe something else (unless your sure you killed the sensor). In any case this will tell you if you did. If you did kill the sensor you’ll really need to replace the heat sink as it’s mounted quite well (epoxied). You will also need to clean off the old thermal paste and refresh the thermal paste with a goo brand.

Hello! I have a similar problem ? When I pulled the cable of the thermal sensor connector of my heat sink the plastic connection broke and now I have only two wires coming out of my heat sink. I can’t plug it back on the logic board. Is there a solution for this or do I need to by a heat sink and a logic board? Please Help! Thanks!
