Rack spacing & cooling


Recommended Posts

Hope to be building my AV rack this weekend.

How much space do I need above (and below?):

AVR (Denon x3300w, Pioneer SC-65)
C4 4-zone matrix amp

Any recommendations on a very quiet rack fan?

Amazon has awesome 2u rack fans that have a screen and temp probe. They're like $100 each. I have one above each receiver and amp. You can also remove the fans and reverse them so the pull of heat is reversed. 


All my stuff is in a closed rack, but the rack is in a room that's kept at 60 so that helps a lot too. I find my denon AVR heats up much quicker than my C4 amp.

Remember that the room also has to have heat removed, no use blowing around hot air through components. Middle Atlantic did a great PDF about it ... I will see if I can find it for you.

Found it ... attached.


Educational, thank you. Very helpful. Confirmed my choice of using variable speed fans.  Venting it out the top/front should send the heat right into the return air duct.
