Valve to Address Early Overheating Warning on Steam Machine with BIOS Update

• July 13, 2026

Valve has acknowledged an issue affecting the Steam Machine’s thermal protection system, which has been triggering overheating warnings prematurely. The affected mini-PC was designed with thermal safeguards to alert users when the central processing unit (CPU) or graphics processing unit (GPU) reach high temperatures. However, reports indicate that the alert system activates earlier than intended, potentially leading to unnecessary concern or performance throttling.

Upcoming BIOS Update to Adjust Thermal Warning Thresholds

The premature activation of the overheating indicator has been confirmed through direct communication between a Steam Machine owner and Valve’s support team. According to the information shared, the existing thresholds for triggering the overheating alerts are set at 90 degrees Celsius for the GPU and 95 degrees Celsius for the CPU.

Valve plans to release a BIOS update that will recalibrate these limits, increasing both GPU and CPU warning temperatures to 100 degrees Celsius. This adjustment is expected to bring the thermal warning system in line with more typical operating temperatures for gaming hardware, reducing the occurrence of false-positive overheating alerts.

While the Steam Machine remains a niche product in the gaming ecosystem, effective thermal management is critical to maintaining optimal performance and user experience. Valve’s BIOS update aims to improve system reliability by refining hardware monitoring capabilities to better reflect actual thermal conditions.

No specific timeline for the BIOS update rollout has been disclosed. Users experiencing early overheating indications should monitor Valve’s official channels for further announcements and update instructions as they become available.

Valve will release a BIOS update to correct the Steam Machine’s overheating indicator, raising temperature alert thresholds for CPU and GPU.
