One other note... the slim PC fans will do better in the space you have, but ideally you need to completely redirect the air from that slot. When I had my AVR in a closed cabinet, I sued this... more expensive, yes. But, it drew fresh air in and through the AVR and directionally vented the hot air away.\nhttps:\/\/www.amazon.com\/AC-Infinity-Front-Exhaust-Receivers-Components\/dp\/B078PQJSRY\n\nFor me, i needed the front exhaust. They also make these with top exhaust (nothing but free open air above) and rear exhaust (Preferred!). :)\n\nIf you have space behind your equipment, I would strongly advise use of a rear-exhaust unit.
