As I am waiting on the 990 to be delivered, I went ahead and downloaded the owners manual to get a head start.
The manual states 6" clearence on sides with an open back. My question is, how hot/warm does the 990 run? I was uner the impression that pre pros don't creat any heat.
I do run 3 fans in my equipment rack, I'll only be able to get 1 1/2" on sides and 2" on top of 990.Heat hasn't been a problem in my rack even though my equipment runs very warn. As it is, everything is cool to the touch.
