Notes:
1) Base plates are nominal 12 mm thick.
2) If heat sinks shown in fig.2 are required without
the fan cowling then the overall width should be reduced
by 3 mm.
| Test results were obtained using the
fans listed below: |
| * |
80mm square Papst fan type 8314H |
| ** |
Comair Rotron 125mm square Galaxy fan type GL124B |
| † |
Comair Rotron Maltese fan type MT24B3 |
| †† |
Comair Rotron Caravel fan type CL3L2 |
| ‡ |
Two 120mm square Papst fans Type 4650N |
Self adhesive foam gaskets are available
as an alternative to screw fixing for attaching 80mm
square fans to the heatsinks. |
