How to Check the Internal Temperature of a Laptop
As laptop computers become smaller and computer components become more powerful, heat is a natural byproduct. Laptops tend to produce a great deal of heat when they are new, and the problem only worsens from there. Over time, dust enters the laptop's cooling fan, causing it to spin more slowly and push less air through the computer. This can lead to dangerous temperature increases. You can use Core Temp, a freeware utility, to check the internal temperature of a laptop CPU.
