SK0-005 Question #199: Real Exam Question with Answer & Explanation

Question

A server technician installs a new CPU and heat sink in a server and reconnects all of the cables. After powering on the server, the technician discovers the server is now overheating. The technician ensures the fans in the server are all operating properly. Which of the following power and cooling components is the next MOST likely cause of the temperature issues?

Options

• AThe server is missing a fan shroud.
• BThe power supply voltage is incorrect.
• CThe thermal dissipation of the heat sink is insufficient.
• DThe power consumption of the CPU is too high.

Explanation

After installing a new CPU and heatsink, if the server overheats despite functioning fans, the next most likely cause is a missing fan shroud disrupting proper airflow.

Common mistakes.

• B. Incorrect power supply voltage would typically manifest as system instability, component damage, or failure to power on, rather than directly causing an overheating CPU with working fans.
• C. While insufficient thermal dissipation by the heatsink is possible, it is less likely the next most likely cause after checking fans, assuming the new heatsink is appropriately sized for the CPU; often, an airflow issue (like a missing shroud) is a more common installation oversight.
• D. Excessive power consumption by the CPU could cause overheating, but modern CPUs have thermal throttling. If the CPU is overheating despite working fans and a correctly sized heatsink, an airflow efficiency problem, such as a missing shroud, is a more probable immediate cause.
