Fan Assisted-Type Heatsink - 225mm Long

The heatsink extrusion has "screw flute" centre to enable 4 x No.6 self- tapping screws to fasten an 80mm standard type fan on one (or both) end/s to drive air through the heatsink assembly.

It is ideal for high power amplifiers and power supplies. The entire assembly, including fan/s can still fit inside a 2 x Rackunit (88mm) enclosure.

The centre groove, for example, is directly below the middle fin.
