Since all the power of Google Stadia is up in the cloud, it can run on even super low-end hardware, including the streaming dongle of Google Chromecast. Some early Stadia players however, report that their Chromecast Ultra units overheat to the point that they turn off while playing games.
Quite a few Stadia players with the same experience have chimed in on a Reddit article. Google’s dongle simply shuts down without warning while playing games on the new streaming service. If you restart the device manually by unplugging the device and then plug it back in, the touch is extremely hot.
What’s happening here? Okay, there’s nothing new about Chromecast Ultra running hot to touch. The Ultra will heat up very dramatically when streaming 4K video since it was launched a few years ago. Even when left completely idle overnight, the unit will stay warm to the touch.
In this case, the concern is that extended Stadia sessions on Chromecast Ultra cause the device to overheat to the point where it can’t run and shut down safely anymore. The user who started this Reddit thread reported that at the time when the Ultra shut down, their session reached 4 hours.
While streaming video, this would also be a concern, but in that case, it seems to be at least less common. Google has yet to comment on this issue of overheating, but if you were planning to play Stadia on a Chromecast, this could be something to keep in mind. Hopefully, an update of firmware can help to solve this problem. If not, Stadia users might be helped out by some third-party cooling solutions or a ridiculous modification.
