Pro Good performance for the price
The Swift 3 performs quite well for the price and laptop class it belongs to. Everyday tasks are handled without problem, multitasking is not a problem neither, and it can also play some lightweight games (DoTA, LoL, Team Fortress 2) at decent framerates as well as some more demanding software such as Photoshop and Mathlab without overheating the hardware or lagging.
Con Fairly noisy
The Acer Swift 3 has two small fans which sit on the CPU and GPU. Unfortunately they are rather agressive and start spinning even at low temperatures. Even something as simple as opening a browser will prompt both fans to start spinning quite fast. If you also keep in mind that both these fans have a fairly high pitched hum, then it's soon clear that this laptop is not the quietest on the market.
