Overview
- Valve confirmed Monday that a known BIOS configuration error can make the Steam Machine’s red LED overheating indicator light up earlier than it should.
- Steam Support says a BIOS update is being prepared to change the red‑warning thresholds from the current settings to 100°C for both CPU and GPU, but it has not given a firm release date.
- Support reviewed user screenshots and said the reported unit was within normal operating temperatures and that the device is set to throttle performance at about 100°C and to shut down if temperatures rise further.
- The issue was first flagged by Reddit user Pure-Outcome-5977, who shared telemetry showing the red bar active while the CPU read about 81°C and the GPU about 71–81°C, and the light‑bar behavior appears to be unit‑dependent and similar to past premature ‘Red Line of Death’ reports.
- Owners should follow Valve’s support guidance, monitor system temps with software, and expect fewer false alarms after the BIOS fix which should reduce gameplay interruptions and rely on the Steam Machine’s built‑in throttling and shutdown protections.
