As soon as I open Vivaldi, the fans of my computer become crazy and very noisy. As soon as I close it, everything goes back to normal. It seems that the last versions require a lot of system resources. My computer is an ASUS G74SX with a Core I7 and 8 Go of RAM. I didn't notice this problem with oldest versions. (I'm using the development version 1.3.551.13) Can you solve this problem ?
