All heatsinks are suitable for Natural Air Cooling (AN) and Forced Air Cooling (FC). In addition to a vast experience of AN and FC cooling methods we also have many years experience in liquid and phase change cooling.
A range of coolers for 17mm to 100mm silicon diameter devices is available, as is a range of associated clamps.
