In looking at the AC Infinity systems, it appears that they are designed to pull the hot air from the receiver or amp and exhaust it through the top, back or front. I thought BLOWING air onto the heat sinks and that amp itself would be more beneficial than simply sucking the hot air and exhausting it. Am I wrong? All the homemade fans I have BLOW the air toward the fins... Also given the uneven top on the 400 and the 700, which one of these models would do the best job?
I am interested in everyones opinions..
