Northbridge 2 temperature sensor fail
I have a problem with my Macbook Pro. When I start up my Mac fans starts spinning at 6200RPM and it becomes freaking slow, even the cursor starts lagging. I checked the temps on an older iStat, and I find that when the Northbridge 2 shows temp between 30-50 degree Celsius than everything works fine, but when it shows 128 degree the problem happens.
Where is this sensor? How can I fix it?
I attached a picture of the iStat temps, the other 129 degrees doesn't cause the problem as they always show that, only the Northbridge 2 slows my Mac.
