Reciever cooling requirements

I am building an entertainment center that will have my reciever in a very confined space. The space is 21" wide x 20" deep x 9" high. The reciever is rated at 600 watts. What is the minimum cfm cooling fan I would need to get to to protect the reciever? The fan would be in the back (enclosed with fan mounted in it) and likely pushing the air out the front which would be an open space when in use.

I've used thermally controlled muffin fans to control heat. The fan starts as the heat rises. They make a 12vdc one where the thermal control for variable speed is built into fan and you just supply it 12vdc. Others like in the link below come with a separate thermostat to control the fan.

Don't really want a thermally controlled fan. Looking at fans that will plug into the accessory a/c plugs on the back of the unit so the fan would be on anytime the reciever was on. I was just curious how many cfm I should be looking at for the space (approximately 2 cu ft). Don't want to go too overkill as that tends to add price and more noise.

Do receivers still come with AC receptacles on the back. I haven't seen any in ages.

Get a 4" whisper muffin fan. Even quieter is a blower. They move more air at lower speeds.
20-30 cfm is all you need.

Many used blowers can be found on eBay.
