- There’s a new red light issue with the Steam Machine
- This time a solid red light is being displayed which indicates the device is running hot
- That isn’t necessarily the case, and in fact the Steam Machine’s temperatures can be normal, and a bug in the BIOS can cause the light to come on
If you’re an early adopter who’s been worrying about a red light being displayed by your Steam Machine while gaming, then there’s not necessarily anything to panic about, as apparently this temperature warning light is being mistakenly triggered.
VideoCardz noticed a thread on Reddit where the original poster shares correspondence from Valve’s support team about what’s happening in terms of the red light coming on when the temperature is nowhere near the intended warning threshold.
As per Valve’s FAQ on the Steam Machine’s light bar, the red light comes on solidly (across the whole bar) when the device is deemed to be overheating, meaning the CPU temperature is over 95C or the GPU is over 90C (or indeed both).
The Redditor noticed that the red light was on when their Steam Machine was at temperatures of 75C and 81C for the GPU and CPU respectively, neither of which should have caused the warning light to appear.
As the message from Valve explains, there is a “known issue with the current BIOS” that means the red light comes on “much earlier” than it should.
The problem is entirely related to the temperature threshold for the light, and the Steam Machine is not overheating in any way in these cases, it should be noted.
The message from Valve informs us that a BIOS update will be coming to fix the problem soon. In fact, that update will increase the threshold to 100C for both the CPU and GPU, which is the point at which the Steam Machine will throttle the components to ensure they don’t get any hotter.
In case you were wondering, if either the CPU or GPU does get any hotter than 100C, the device will then shut down to protect itself from any potential damage.
Analysis: false alarm
What this means is that if you’re seeing the red warning light a fair bit, it’s likely a symptom of this overkeen BIOS which is turning on the light way earlier than it should be. Odds are that your CPU and GPU are running cool enough, and you can check this using the Steam performance monitor or a third-party tool as the Redditor did.
In any case, even if you do see the red light and it’s correctly indicating temperatures at Valve’s threshold levels, this isn’t going to damage the Steam Machine – it just means the components will be throttled back to run slower to prevent any such damage. If that doesn’t work, and the component temps aren’t brought back under control, as noted the PC will turn itself off to avoid any potential GPU or CPU-frying scenarios.
It’s not a pleasant thought that your Steam Machine is throttling and not running as fast as it should, though, if this happens – but based on this (and other) reports of this incident, that isn’t the case, and the only error is the light showing when it shouldn’t. There’s no actual overheating, throttling, or anything else going on under the hood.
If you’re worried that Valve’s new temperatures for throttling and the warning light seem high at 100C, this is in line with what’s to be expected from AMD laptop parts (which are what’s used for the Steam Machine’s CPU and GPU).
For now, all those who have bought one of Valve’s gaming PCs can do is wait until the next BIOS update which should hopefully fix this problem. It’s also worth noting that the ‘Red Line of Death’ is a completely separate issue, and we’ve had some troubleshooting advice on that knottier problem since it was first highlighted.
