Xbox 360 Thermal

Xbox 360 SMC Error: 0011, 0012, 0013

ERROR_THERMAL_CPU, ERROR_THERMAL_GPU, ERROR_THERMAL_EDRAM
Thermal Runway in CPU, GPU, or eDRAM

Determine Thermal Runway Source


 * 0011
 * CPU die is overheating
 * Phat: Focus on CPU heatsink


 * 0012
 * GPU die is overheating
 * Phat: Focus on GPU heatsink


 * 0013
 * eDRAM die is overheating
 * Phat: Focus on GPU heatsink


 * Slims only have one heatsink for the combined CGPU

Thermal Transfer


 * Check thermal paste is wet and applied properly
 * If the paste is dry or poorly applied, clean the paste completely and apply new paste
 * If a damaged heatsink is suspected, try another heatsink

Corona Resistors


 * Skip for Phat or Trinity
 * Corona boards have 0 Ohm resistors on the thermal sensor lines
 * If the resistors increase in resistance, the thermal sensors will read high
 * Check the 0 Ohm resistors on the thermal sensor traces:
 * 0011 - CPU:
 * R4D7
 * R4D8
 * 0012 - GPU:
 * R4D5
 * R4D6
 * 0013 - eDRAM:
 * R4D3
 * R4D4

ANA/HANA/Southbridge


 * Replace thermal sensor control chip:
 * Xenon: ANA U4C2
 * Zephyr, Falcon, Jasper: HANA U4C2
 * Trinity: HANA U3B1
 * Corona: Southbridge U3D1

CPU/GPU
 * Assume thermal diode has failed
 * Warning: Do not attempt to circumvent the thermal diode, doing so will cause the console to be dangerous to operate
 * Replace the chip containing the faulty thermal diode
 * Phat:
 * 0011: CPU U7D1
 * 0012: GPU U4D1
 * 0013: GPU U4D1
 * Slim: CGPU U5E1
