Steam Deck Internal Fan (Huaying)
The cooling fan is the primary active heat dissipation component; failure to maintain adequate CFM or static pressure leads to heat soak in the copper heat pipe. Replacing a failing or underperforming fan ensures that the radiator fins are cleared of heat before the APU reaches its thermal shutdown threshold. The Huaying variant is the preferred OEM replacement due to its superior reliability and noise profile.

High-Performance Thermal Paste (Honeywell PTM7950)
The Steam Deck APU relies on a phase-change material or high-viscosity TIM for heat transfer to the cold plate. Standard thermal pastes often suffer from 'pump-out' due to the thermal cycling of the handheld, leading to air gaps and immediate overheating. PTM7950 is the industry standard for this specific hardware to maintain long-term thermal conductivity.

Steam Deck Heat Pipe Assembly
If the internal vacuum of the copper heat pipe is compromised or the working fluid has leaked, the thermal conductivity drops significantly. This results in the APU overheating despite the fan running at maximum RPM. Replacing the full assembly restores the phase-change cooling efficiency of the vapor transport system.
