Without knowing the entire dimension of that shelf...no. Even tiny little fans like this... http://www.amazon.com/Westpointe-Electrical-Velocity-1002-Personal/dp/B000WEIJ7K/ref=pd_sim_pc_7 (there are tons, just depends which ones you find in the right dimensions) Paired up in two. One of each side of the AVR...one blowing in, the other blowing out.. They wouldn't even need to be "out front". They could sit at the back corners at 45 degree angles...as long as they created a flow.
