Mass-Air-GPU Heatsink System


The "Mass-Air-GPU" heatsink system consists of:

  • Formed aluminum high flow air duct, anodized for a durable long lasting finish. Duct is mated to a custom laser cut and formed stainless steel I/O bracket
  • High performance, low pressure drop, low thermal resistance heatsink with imbedded copper heat spreader
  • Two stainless steel mounting screws, locknuts, and precision stainless steel preload springs


The high performance heatsink uses a copper heat spreader to distribute the heat evenly into the aluminum fins. This heatsink was designed by Alpha to passively cool a FC-PGA2 style CPU chip. The fins are very thin with wide spacing between each fin. This decreases the pressure drop across heatsink allowing for a higher volume of unrestricted airflow.

The heatsink is held in place by two pre-load screws. Each screw has a nylon washer under the head to protect the backside of circuit board. A precision coil spring above the heatsink applies equal pressure to the processor support plate. The springs also allow for expansion and contraction of the heatsink.


The large, high volume air duct allows for unrestricted air flow across heatsink. The air duct consists of a formed aluminum duct riveted to a stainless steel I/O bracket.


"Mass-Air" heatsink system installed in case with the air intake duct. The large heatsink and air duct occupy the PCI slot adjacent to the video card. The air duct is held in place by the I/O slot rail.


Shown above is new 9600 XT version.
