Some fans are automatically temperature-controlled -- they speed up, and, of course, make more noise, as the temperature rises.
Background tasks, such as Windows Automatic Update and scheduled virus-scans, can cause the computer to become "busy" when otherwise "sitting unused".

Click the "Processes" tab, and then click on the 'CPU' column-heading, and click it a SECOND time, so that Windows lists the "top" consumers of CPU at the top of the list of processes. Which process is consuming the majority of the CPU?
