The 12 V computer fans work fine for this purpose. They are available
from a lot of mail order places and can also be found at hamfests.
I think that MCM Elecronics sells a temperature sensing one. I bought
a temperature controller kit for about $ 7.00, nade by Rainbow Kits,
but I haven't tried it yet. The only trick is fabricating a mount for
the fan without drilling holes in the heatsink (hot melt glue and tape
not recommended).
