Beefy LED cooler

"I wanted to get a fully fanless PC for quite a while, but when I saw that the newer energy efficient AMD laptop processors come with a halfway decent 760M iGPU and pack quite a bit of CPU punch, enough for older games, emulations and also CAD work I was sold on the idea and used an ASrock Industrial Box 4x4 7640u as basis for my own design.

It is a quality LED heat sink from Wakefield-Wette bought from Digikey and is rated for 33W convection based heat dissipation. From my experience, those specs are pretty accurate, it can handle the 28W TDP CPU pretty well."
