However, I found a little 12v DC fan (about 3-1/2" square x 1" high) and stuck it on top of the heatsink with double-sided tape. I oriented it to blow downward and put a 100-ohm resistor in series with it to slow (and quiet) it down. It makes a BIG difference in heatsink temperature, and I presume in drift as well. Vic K2VCO
