The CPU started overheating suddenly out of nowhere. I was watching youtube and the fan started working like a jet engine, didnt stop no matter what, I even restarted windows but it didnt stop for a second, I then turned it off and turned it back on and the fan was working normally. Now it seems that the CPU is idling at and average of 85 Celsius, but the fan is working like before the issue, pretty quiet, even though temp is now 90C, tried a game real quick it was around 100C, this wasnt the case just a hours ago, now this is the new normal. I tried installing the new ASUS interface controller driver and intel thermal drivers but that did nothing. I am on the latest BIOS, and the Laptop just came back 2 weeks ago from repair at the local ASUS lab.

UPDATE: It seems to have relaxed, now I get an average of 65C on idle.
Here is the last 15 minutes reading of temps (not much is happening, a few tabs in chrome one video playing on youtube, and some minor apps in the background):

I really don't know anymore with this laptop, are these readings normal? if anyone has insight regarding these numbers it would be greatly appreciated..

maybe it has tons of dust and the fan not working properly or you got malware or something

I've also noticed something similar to this. When idle with lid close, sometimes the laptop gets very overheated, but not all the time. I haven't figured out the issue yet.
