SK0-005 troubleshooting Practice Question
A data center technician is troubleshooting a server that is overheating and shutting down intermittently. The server is a 2U rackmount with six fans at the front and a power supply with an integrated fan at the rear. The technician checks the ambient temperature (72°F) and verifies that the server intake temperature is normal. The server's system logs show 'CPU temperature threshold exceeded' before each shutdown. The technician has replaced the thermal paste on the CPU and reseated the heat sink, but the issue persists. Which of the following should the technician 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
✓
Replace the chassis fans with high-static-pressure models
Option B is correct: the fans may be running but not at full speed due to a faulty fan controller or sensors. Option A is wrong because ambient temp is fine. Option C is wrong because CPU is already reseated. Option D is wrong because power supply is not indicated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Move the server to a cooler location in the data center
Why it's wrong here
The ambient temperature is within acceptable range, so moving the server would not significantly improve cooling.
- ✗
Reinstall the CPU heat sink with more thermal paste
Why it's wrong here
The thermal paste has already been replaced; adding more or reapplying is unlikely to resolve the issue.
- ✓
Replace the chassis fans with high-static-pressure models
Why this is correct
Fans may not be spinning at sufficient RPM despite being operational. Upgrading to higher-performance fans can improve airflow over the CPU heat sink.
- ✗
Replace the power supply unit
Why it's wrong here
The PSU fan is integrated, but the logs point to CPU temperature, not power supply failure. Replacing PSU would not address the root cause.
