My CPU is definitely defective. I ran a Fast CPU Stress Test and it went to 98 Celsius without shutting down! Or it overrides the response. Still, during browsing with at most 9-10 tabs open, i get 50-70 degrees and 30-40 idle temp.
Mine has been doing the same shutdown. I've even been using a cooling fan underneath laptop. To be honest I don't know a lot about laptops or CPUs and I don't know if it's part of the issue or connected in anyway but so far mine has only done it when I have the charging cord plugged into my computer and charging. It seems to do it no matter what temp CPU is but when plugged in...so far anyways for me.
