Xbox 360 Thermal

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 grove 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, Stingray, and Winchester
 * 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
