How do u know it's the processor. After all u can't touch it. It should actually be the fan and the dust on the heat sink. Unless u have removed the heatsink a couple of times.
The motherboard, CPU, and RAM is brand new. So no dust issues. I touched the heat sink to confirm the temperatures were indeed high.
So the heat sink is not disspating heat. If it was working well earlier It means the fan has slowed down. Or U are overclocking If not u need better heatsink / faster airflow / lower ambient. Put a fan in the box.
So the temperature sensor is not malfunctioning. The vendor had to remove the heatsink a couple of time when he switched the board. The first one I had gotten was a dead one...
Thermal grease will reduce thermal resisitance between the processor and the heatsink. This will raise the temp of the heatsink and lower the die temp by a few percent points.

No. Actually, originally the board that I got was dead. So, in the process of replacing the board, the processor + heatsink was removed. This "cracked" the thermal pad below the heat sink. While refitting the heat sink on the new board, the "cracked" thermal pad must've moved a bit out of position. This is prolly the reason for the high temperatures. The fan is working well. No problem with it. According to AMD's docs, we are supposed to replace the pad everytime we remove the heatsink from the processor. I should've done that but due to my "ignorance" I couldn't buy a new thermal pad / grease....

So you recommend the grease over the pad?
