這種新技術名為“桑迪亞散熱器（Sandia Cooler）”，
學名為“空氣軸承熱交換器（Air Bearing Heat Exchanger）”。
該技術的特點就是讓原本靜止的散熱器鰭片高速旋轉，以加快熱量的散失。
據實驗室的研究人員稱，目前風冷散熱器真正的熱交換瓶頸不是熱管或金屬的熱傳遞效率
，而是附著在散熱片上的靜止空氣（dead air）邊界層，即使是使用風扇進行主動散熱，
這個靜止空氣邊界層是依然存在的，而且厚度足以影響整個散熱器的散熱效率，因此
他們打算讓散熱鰭片旋轉起來，利用離心效果將這個邊界層的厚度削減至最小。

底座和旋轉層相距25微米(1英吋的1/1000)
連結有原型實驗成品,有影片,對照表(跟塔式散熱器對照),體積更小,噪音也低,減少積塵
Sandia說製造成本低於10美元
