We went hands-on with the Svalt D to test the claims that it reduces temperature and speeds up performance, and we were impressed with how it worked.
Made up of a two-pound block of aluminum, the Svalt D is an attractive, sturdy stand that matches well with Apple's line of MacBooks. The Svalt D houses a small stand that moves air through a MacBook, and thanks to an adjustable rubber foot, it's compatible with all of Apple's notebooks.
To test the Svalt D, we exported two different videos from a MacBook, with and without the dock. Without using the dock, exporting a video took 15 minutes and caused the temperature of the MacBook to rise to 121 degrees Fahrenheit. With the stand, our video exported in 14 minutes and the stand kept the MacBook at 105 degrees Fahrenheit, a 16 degree difference.
Our one complaint about the Svalt D concerned the two modes of the fan. There's a normal mode and a silent mode, but switching between them requires using a special standalone cable, which is a bit of a hassle and an extra expense. Luckily, both modes are relatively quiet and don't make as much noise as a MacBook fan, but the silent mode is definitely a better choice for users who want the quietest possible performance.
In our opinion, the Svalt D is a solid dock that lives up to its claims, keeping your MacBook cool when it's used with an external monitor. The Svalt D is available in Silver and Black and can be purchased from the Svalt D website for $149.95. The Silence Adapter is available for $8.95.
