Since thinner laptop bodies can run into overheating issues, Dell worked on several ways to keep the x15 and x17 cool. The laptops have five patent-pending designs centered around cooling that are exclusive to Alienware.

The x15 and X17 feature the next generation of Alienware Cryo-Tech cooling technology. Part of that tech is Element 31, which is a thermal interface material made from Encapsulated Gallium-Silicone liquid metal compound. Dell states that the X-Series laptops deliver up to a 25% improvement in thermal resistance over competing products thanks to Element 31.

The laptops also have more traditional cooling methods, such as Alienware's (patent pending) Quad Fan design. That fan is controlled by Smart Fan, which uses AI to improve application performance. The laptops sport vents on their backs, tops, and bases.

The Alienware x15 and x17 will be available on June 1, 2021, starting at $1,999 and $2,099, respectively. At launch, both laptops will be available in a limited number of configurations. On June 15, 2021, all configurations of the laptops will be available for purchase.
