I recently had a new fan installed on my laptop because the old one died on me, and even though the new fan is working fine I'm having overheating problems now. I didn't know what the problem was at first until I checked my laptops temperature readings using speedfan. At first it made sense that my laptop was turning off from overheating, but after checking out the readings something doesn't add up. The temperature will shoot up from 20 degrees celcius to 100 degrees celcius in less than 2 seconds. At the same time my computer will still feel very cool so it doesn't make any sense. This has never happened before and is very frustrating since my computer shuts down as soon as the temperature reads 100 C. Therefore I think that if I recalibrate the temperature sensors either this problem will go away or I'll realize that I finally need a new laptop. If anyone knows any way possible to calibrate the sensors please feel free to give any advice as it is greatly appreciated.
