A CPU fan is a component that cools down the CPU, which is the main processor of the computer. If the CPU fan is failing, it can cause the computer to slow down and the fans to alternate between silent and very loud12. This is because the CPU fan cannot maintain a consistent speed and airflow to keep the CPU at a safe temperature. When the CPU gets too hot, it throttles its performance to avoid overheating, which results in a slower computer. The other fans in the computer also try to compensate for the lack of cooling from the CPU fan by spinning faster and louder2.

A client-side hypervisor is a virtual machine monitor (VMM) that resides in and virtualizes a user’s computer, allowing it to run multiple operating systems (or virtual machines) on shared hardware12. A client-side hypervisor can be useful for a software developer who needs to test an application in many environments, such as different versions of Windows, Linux, or Mac OS. By using a client-side hypervisor, the developer can switch between different virtual machines without rebooting the computer or using multiple physical devices3.

TPM stands for Trusted Platform Module, which is a hardware component that securely stores encryption keys and other sensitive data12. TPM can be used to enable hard drive encryption, which is a technology that encrypts the data stored on a hard drive using sophisticated mathematical functions34. Hard drive encryption protects the data from unauthorized access in case the hard drive is lost, stolen, or tampered with.
