5.2.3.1 Processor Thermal Control % Sensors – Next Steps
These events normally occur due to failures of the thermal solution:
1. Verify heatsink is properly attached and has thermal grease.
2. If the system has a heatsink fan, ensure the fan is spinning.
3. Check all system fans are operating properly.
4. Check that the air used to cool the system is within limits (typically 35°C).

processor E5-4600/2600/2400/1600 v2 product families are incorporating a DTS-based thermal spec. This allows a
much more accurate control of the thermal solution and enables lower fan speeds and lower fan power consumption. For Intel
