I am thinking of adding a fan to my MES for jerky making. Not sure what benefit it would provide for regular smoking but there would certainly be more air movement across the meat. I had thought about this for a while and have a few 3" computer fans that I had bought for my winecooler humidor. They were so cheap I bought a half a dozen to justify the shipping. Well the fan in my computer's power supply started making a racket. Bearings are shot. What do you know it's a 3" fan. Glad a had a spare. So I took the old fan and stuck it on an extra elbow I have for the MES from my cold smoke generator making. It fits like a charm. Now that I know it's an easy fit I'm going to wire it to one of the many DC power supplies I have collected from all the old electronic gadgets that have come and gone. Well see how it goes and report more in the future.
