0011 - ERROR_THERMAL_CPU

The SMC monitors the CPU thermal diode as reported by the ANA/HANA. If the CPU temperature exceeds the trip temperature defined in the SMC Config, the SMC enters EC_THERMAL and the 0011 code is displayed on the front panel.

0012 - ERROR_THERMAL_GPU

The SMC monitors the GPU thermal diode as reported by the ANA/HANA. If the GPU temperature exceeds the trip temperature defined in the SMC Config, the SMC enters EC_THERMAL and the 0012 code is displayed on the front panel.

0013 - ERROR_THERMAL_EDRAM

The SMC monitors the eDRAM thermal diode as reported by the ANA/HANA. If the eDRAM temperature exceeds the trip temperature defined in the SMC Config, the SMC enters EC_THERMAL and the 0013 code is displayed on the front panel.

Runway Source

  • Original Xbox 360:
    • 0011: CPU Die, CPU Heatsink
    • 0012: GPU Die, GPU Heatsink
    • 0013: eDRAM Die, GPU Heatsink
  • Xbox 360 S and Xbox 360 E:
    • Only one heatsink for the combined CGPU

Heatsink Attach

  • Check that heatsink is oriented properly
  • Check that the X-Clamp is not bent, and the claws fit into the groove on the heatsink peg

Thermal Transfer

  • Check thermal interface material (TIM) is properly applied
    • If the seal between the TIM, die, and heatsink is disturbed, the TIM must be cleaned and replaced
    • The Original Xbox 360 uses a phase change pad as TIM. This pad will only work properly once reflowed during manufacturing. It cannot be reused once the seal is disturbed.
  • Check if the heatsink is damaged, if it is, replaced it

Thermal Diode Resistors

  • Only applies to Corona, Waitsburg, and Stingray
  • These motherboards have 0 ohm resistors on the thermal diode traces
  • Check the 0 ohm resistors for the corresponding error:
    • 0011 - CPU:
      • R4D7
      • R4D8
    • 0012 - GPU:
      • R4D5
      • R4D6
    • 0013 - eDRAM:
      • R4D3
      • R4D4

Thermal Diode Controller

  • If the thermal diodes are functioning properly, but incorrect temperatures are being sent to the SMC, the thermal diode controller may have failed
  • Replace the ANA, HANA, or KSB depending on which the board uses

Thermal Diode

  • 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 CPU/GPU/CGPU, whichever contains the faulty thermal diode
