hi everyone. i built a decent smoker a few months back and have been wondering if i put in a small fan to create air circulation will my cooks times be better. there is a definite temp difference from rack to rack. this has been quite noticeable when i fill it up with ALOT of sausage. the links on the top will come up to the IT faster and then i remove them and move the other stuff up. do you think a small internal fan will give me better heat throughout? if yes.... where would be the best spot to place it? blowing over and across the electric elements .. and does anyone have a place where i could order a fan with a 2 to 3 inch shaft that i could install on the outside of my fridge and only have the shaft and fan on the inside.... here is my build , i have since put another fin strip heater mounted above the brinkman and under the guard/deflector. thanks for any help !!!
