You’ve recently installed a new motherboard and CPU, and you’re interested in monitoring the CPU heat during the burn-in process. Which of these would be the best way to check the temperature of your CPU while under load?

A) Use a thermometer in the case with leads that connect to the CPU

B) Measure the temperature of the air going into and out of the computer and compare the difference

C) Use specialized software to measure component temperatures

D) Use infrared thermometers to measure the CPU temperature from a distance

E) Look at the CPU and write down your best guess of a temperature value
