How to Find Out the Temp of Your Laptop
Every laptop uses components that create heat inside the casing, and all of these components are packed tightly together. Most laptops use thermal grease treatments and heat sinks so that the CPU is not damaged by excessive heat while the laptop is running. Depending on the make and model, overheating can cause your laptop to suddenly shut down, experience catastrophic hardware failures or even catch fire. A good first step in preventing such disasters is to know the laptop's operational temperature during normal usage. Most laptops have built-in sensors that you can use with utility programs to detect the internal temperature in real-time.

Tips & Warnings
Regular annual replacement of the thermal grease that protects the CPU will reduce the likelihood of your laptop overheating.
When the laptop is turned off, use compressed air to blow away any dust that accumulates near or in the air vents and fan. Dust can clog the air passages and cause the laptop to overheat or catch fire.
Some temperature monitoring utilities permit the setting of notification triggers. If the temperature goes either too high or too low, a warning will display so you can take an appropriate action.
Any spiking in the temperature readings should be investigated right away. Big fluctuations in temperature readings may indicate imminent hardware failure.
