Hello there I have the exact same issue as the following member but on my x15 R2. My laptop can work for days and play games smoothly without any issiues as long as i dont turn it off or restart. Once shutdown or restart it would give 2red 3blue error code and it can take a while before u can start it up again. I have observed the temps during high end gaming and it never went beyond 90 so that's fine. I also noticed if I put my laptop in food freezer for around 10min it would start up normally and I can use it for days and days just as long as I don't shut it off.
