I need advice: I plan to use a heat-sink for cooling 2x 80W white LEDs over my friend's tank. The heat-sink is a "pin fin" design, 6 inches by 6 inches which combined with active cooling should dissipate more heat than other fin designs. Here it is:
Now, I plan to attach 4x 12-volt fans on top for strong active cooling. My question is would such a system cool 2x 80W warm white LED chips effectively? I know LEDs aren't very efficient, and only a percentage will be actual heat produced, a few degrees above operating temp is no bother for us, so bearing all this in mind is this 4 FAN "pin fin" heat-sink idea feasible enough to effectively cool both 80W chips?.
