A technician is installing a new CPU into a motherboard. After placing the CPU into the socket, what is the next critical step to secure it and ensure proper electrical contact?
- AInstall the CPU cooler mounting bracket.
- BLower the retention arm or lever onto the CPU.
- CApply thermal paste to the CPU surface.
- DConnect the CPU fan power cable to the motherboard.
Show answer & explanationAnswer & explanation
Correct answer: B. Lower the retention arm or lever onto the CPU.
After placing the CPU into the socket, the retention arm or lever must be lowered and locked to secure the CPU physically and electrically. This ensures all pins or lands make proper contact with the socket.
Why the other options are wrong
- A. Installing the cooler mounting bracket is done after the CPU is secured and thermal paste is applied.
- C. Applying thermal paste comes after securing the CPU and before installing the cooler.
- D. Connecting the CPU fan power cable is one of the final steps after the cooler is fully installed.

The process of correctly seating and securing a Central Processing Unit (CPU) onto a motherboard's socket.
- Requires careful alignment with the socket's keying mechanism.
- Retention arm/lever secures the CPU both physically and electrically.
- Thermal paste and a cooler are essential for heat dissipation.
