Due to its narrow ventilation holes, the cooling fans need to spin faster in order to cool the laptop down. It can become so hot that it may become uncomfortable to touch the laptop, though the performance doesn’t suffer and doesn’t cause noticeable thermal throttling.
The Razer Blade is built to be a very portable gaming laptop and Razer certainly have reached that objective. The body is only 0.7inch tall when the lid is closed and it weighs only 4.1lbs. The power brick is very small and light as well.
As far as performance goes, the Razer Blade is virtually the same as most gaming laptops with these specs, however, the Razer Blade costs at least $500 more on average. You are mostly paying for the beautiful design, portability, and build quality.
