No Hi-Tek. I'm talking about a full size house oven the is a Convection oven with a fan in it already. Are the convection ovens not modified any good? I have a house oven I use to PC already. Are there fans I can buy and cut a hole in the side of the oven and add one myself? If they have fans toy can buy and add I would do that. Like I said. I have a full size house oven already but no fan. I'm wanting to know if I can install one myself.
