CMOD Inlet Thermal Sensors

Each CMOD has an internal motherboard-mounted thermal sensor at the front right side just behind the air intake grill. This is the CMOD inlet thermal sensor, designated as U3005. The CMOD inlet thermal sensor is not a serviceable part. Do not allow dust to build up on the sensor or allow blockage to occur at the CMOD air intake grill.
