System temperature showing as 127°C in Predator PC PO3-630

It sounds like you might be experiencing a sensor or calibration issue, especially if the temperature readings are unusually high. Here are a few steps to troubleshoot:

Check Physical Connections: Ensure that the CPU cooler is properly installed and making good contact with the CPU. A poor connection could lead to incorrect temperature readings or overheating.

Verify Sensor Accuracy: Sometimes BIOS or software sensors can give false readings. Try using a third-party monitoring tool like HWMonitor to cross-check the temperatures.

Inspect RAM Installation: Double-check that the RAM is properly seated in its slots. Improper installation could potentially cause system issues, though it's less likely to affect temperature readings.

Update or Reinstall Monitoring Software: Make sure PredatorSense and any other monitoring tools are up-to-date. Sometimes, reinstalling the software can resolve discrepancies.

Consult Documentation or Support: Review the motherboard and cooler manuals for any specific installation guidelines or troubleshooting tips. If the issue persists, consider reaching out to the manufacturer's support for further assistance.

If none of these steps resolve the issue, you might want to check for hardware defects or consider professional diagnostics.
