According to  recent review in PC Mag, the Razer Blade while cooler than before is still quiet warm and also loud.

It seems that a warm noisy notebook is the norm for a gaming notebook computer. Can it  be avoided? well a performance anything really is always going to use more energy which means its going to be needed to be cooled as its going to be hotter to run.

It seems though there are better options our there.

“Fan noise doesn’t seem to be as big a problem this time around, but it’s still quite noticeable.”

“fixing two of the bigger problems I had with the 2014 Blade. Heat is still a big concern”
