From the manufacturer’s perspective, if proper ventilation guidelines are followed/provided...then there’s NO need for additional cooling.Hello,
Do you have an opinion on whether there is a need for additional cooling? I tink to get an AIRCOM T9 Component Cooling Fan System.
From an “objective” and manufacturer’s perspective, your installation appears to be ideal...completely open for optimal cooling. However, from a human/pure “subjective” perspective, the 8012’s Class A/B amps give off significant heat...hot to the touch when high performance demands are required. Even so, per @jdsmoothie, the unit’s own protection circuitry which activate its four internal fans at 158 degrees F have never been reported to engage. One then speculates that D&M design engineers knew exactly what they were doing and humans worry needlessly. On the other hand, it’s common knowledge that heat is the enemy of electronics...period. Heat over time will likely lead to degradation or premature component failure...when and to what extent...no one knows for sure. Bottom line here is the human condition wants to protect its investments...especially those that costs in the thousands of dollars. Therefore, additional external cooling (1) provides peace of mind (2) looks “cool” (3) copies what others are doing (4) only costs about $100...cheap compared to the 8012 and (5) makes AIRCOM very happy.
So...there you have it...pragmatically NOT necessary in your case...BUT, the human condition and marketing says buy one!
