Question 52 of 144
SK0-005 server-hardware-installation-management Practice Question
Several users report sluggish performance from a database server. The server administrator notices that the CPU fans are running at maximum speed and the baseboard management controller (BMC) reports CPU temperatures of 85°C even at idle. The administrator already cleaned dust from the chassis and verified all fans are operational. Which of the following should the administrator do NEXT?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Reapply thermal paste on the CPU heat sinks.
High temperatures persist after cleaning and fan checks suggest poor heat conduction between the CPU and heatsink, typically caused by dried or inadequate thermal paste.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add additional case fans to improve airflow.
Why it's wrong here
With fans already maximized, poor case airflow is unlikely if the chassis is clean. The immediate focus should be on the CPU-to-heatsink interface.
- ✗
Replace the CPU fans with higher RPM models.
Why it's wrong here
If existing fans are functional and dust is cleared, the issue is likely heat transfer, not airflow volume. Replacing fans is less likely to resolve the root cause.
- ✓
Reapply thermal paste on the CPU heat sinks.
Why this is correct
Thermal paste degrades over time. Reapplying it is the standard next step after basic airflow issues have been ruled out.
- ✗
Increase the fan speed thresholds in the BIOS.
Why it's wrong here
Adjusting thresholds would only mask the problem by allowing higher temperatures before speeding up fans, but the CPU is already overheating at idle.
