I did clean my fans. And I use Intel driver&support Assistant to update most of my drivers. Besides that, I actually have manually updated my UHD graphic 630 to the latest version. Do you see a problem of it? 

It could be your fans are dusty. Been a while since you cleaned them?

You didn't happen to update your drivers through a third party program or site? It messed up my computer's ability to cool once.

I just checked the thermal framework, I remember I downloaded it from the Dell website through SupportAssit. These are the Alienware and Intel related software I have. 

Updating graphics drivers is usually very safe in my experience. Be careful with drivers such as thermal framework ones.
