You don't need both push AND pull fans. Replace one of those with just a regular vent and it will move the same amount of air.I know the amp, you got it from me. If you do an enclosed amp rack then a few 80mm fans mounted push/pull is what I'd do...
i got couple fans already i mount one on each side is no issue with amp i just personal preference just to make sure it cool inside enclosed amp rackYou don't need both push AND pull fans. Replace one of those with just a regular vent and it will move the same amount of air.
