You see it correctly... I did not design this amp but it is designed similar to other Peavey amps wrt direction of air flow.moamps said:
There are pros and cons to either way. The air flow coming from a fan is more controlled pushing air than pulling, if you want to keep fan noise down, they need to be in the back, so for controlled air flow that way, direction will be back to front.
The intent of angling in the heat sinks closer together at the hot air end is specifically to increase turbulence and collisions with the heat sink fingers to increase heat transfer at the hot end. Remember the air is still cooler than the devices even at the hot end. Turbulence is actually a good thing in the air flow past a heat sink for improved heat transfer. Smooth, laminar air flow will transfer less heat.
Btw, I like more that the air flow direction is from front to rear of the amp; you can easily clean the filters ( old Crowns). Also there is no hot air blowing in your face. I wander is there any standard for the air direction?
No there is no standard, but best practice is to keep racks full of power amps all with the same air flow direction to prevent circular flow within the same rack. Mixed racks keep all the same direction amps together with an air dam (partition) in the back of the rack to prevent half the amps from pulling already heated air from the other half.
