system was hibernated due to a criitical thermal event

[Garth5]

Computer is new so not a dust/dirty issue... Has happened 3 times now where it is off when I come into work so at night (when not being used) it shuts down ...the event viewer says Event ID88 (System was hibernated due to a critical thermal event) Im a IT guy and realize this a CPU overheating issue but why? It always happens when not in use and sitting idle...so not getting stressed when this happens....maybe fan is quiting? any thoughts ? THANKS!

My guess is that setting are such that Windows Update is enabled to awake the PCs to perform routing updates -- and since WU consumes LOTS of resources, the PCs are overheating and shutting down in the process.

You should read this to see if anything in it helps: https://techjourney.net/prevent-disable-windows-update-from-waking-up-pc-system/
