Many modern motherboards offer temperature sensors at important points like the CPU socket. The motherboard reports the temperatures reported by these sensors to the BIOS. You can see these temperatures by going to BIOS Setup and selecting the option for temperature reporting, which is normally found beneath Advanced Hardware Monitoring, or a similar menu option. Most motherboards have a monitoring utility Intel’s, for instance, is named the Intel Active Monitor—that lets you to see temperatures from Windows instead of going to BIOS Setup. CPU temperature can differ noticeably with changes in load. To check the temperature under load, run an application that loads the CPU with intense calculations, suitably with lots of floating-point operations.
