Outlook 365 causes fans to crank up

[spillerbd]

It could be something other than the CPU usage. Check with the fan profiles and MSI support.
A laptop built for gaming will try and stay ahead of the cooling curve and even an instant of high GPU/CPU usage may trigger the fans to ramp up like that.

I had a Lenovo Desktop that its fans would ramp for no good reason for use of the Chrome browser or FireFox. I could use IE11 without as frequent of issues except for webpage/application compatibility. That was a work PC that the company IT never resolved and wasn't really mine to fix.
