Symptom: The chassis FAN speeds will spin at 100% because the chassis/IOM cannot obtain DIMM temperature readings from a blade. When in this state, the blade can no longer obtain DIMM temperature sensors. Conditions: An invalid I2C transaction occurred on the DIMM I2C bus. These transactions often come from software running on the x86 host.
