The SNS indicates it is a temperature sensor. There are a number of them on the board. To try to figure out where the problem sensor is I suggest you start by downloading and installing iStat, it is a free program, to monitor the various temperatures on your laptop and the fan RPMs. [http://www.islayer.com/apps/istatpro/|Here is a link] to where you can download it from and read about it. The next thing I suggest you do is go through your system log to see what the operating system says is going on when it freezes. [http://www.tech-recipes.com/rx/3521/os-x-how-to-view-log-files/|Here is a link] telling you how to get to your system log file.
-Since it is freezing I would say the problematic heat sensor has something to do with either the CPU or Video chip. You may want to change out and apply new thermal compound to those chips, also clean your heatsink and fan. If you decide to do this I suggest you use Arctic Silver thermal compound. You can find that [product|IF179-010|here.] The instructions for replacing the heatsink will guide you through the process of getting to the heatsink and fan. You can find that [guide|4310|here.]
+Since it is freezing I would say the problematic heat sensor has something to do with either the CPU or Video chip. After you have acquired a temperature profile from the various sensors. You may want to download and install smcFanControl, another free program, you can download it from [http://www.macupdate.com/app/mac/23049/smcfancontrol|here.] That may stop it from freezing since you will have some control over the fan speed. But turning up the fan speed is noisy and it doesn't solve the root of the problem. I suggest you change out and apply new thermal compound to the CPU and Video chip, also clean your heatsink and fan to help prevent permanent damage to those chips. This may even solve your problem. If you decide to do this I suggest you use Arctic Silver thermal compound.

Has your fan been running abnormally high or not at all? Please tell us about the fan operation. Please inform us of the various temperatures and fan rpms iStat is reporting. Also what country are you in?
