I put a 4" computer case fan on my K2/100 heatsink.
I run digimodes in addition to CW with my rig so needed the extra
cooling. I installed the fan with some double sided foam tape on the
corners of the fan. I installed the fan so it blows up, pulling air
through the heatsink.

For those that don't know..... on these small DC computer fans the
direction of airflow is toward the label. If you see the label it's
blowing air in your face.
