Good job, just one suggestion: You should make Front-Exhaust box and not Top-Exhaust because 90% of users storing Receivers in to cabinet and Top-Exhaust will kill other devices including Receiver.
Im not an engineer, but im pretty sure that resistance you mention when the fan is against the vents just requires a fan with better static pressure. Radiators for Pc water cooling use fans like this. Good to see your cooling pad sits flat with your reciever, otherwise because of that resistance more air gets pulled through the fan that isn't from in the reciever. This will cause less air overall being pulled from the reciever, because air will take the path of least resistance. Thats my understaning from my knowledge of atmospheric pressures and tech hobbies..
I'm a little late but... These actually are static pressure fans from a laptop cooling pad. They were designed to only sit about 5-10mm away from the bottom of a laptop. I think the grate on the top and bottom of the receiver create too much air resistance for these little fans. I'm debating making a 90mm or 120mm fan version. I think it would work much better and quieter. I'm also going to make the new version with a digital thermometer, that way the fans aren't running 24/7.
