Hi guys, I'm calculating the dimensions of an aluminium passive heatsink for my setup. After some study I got that my cobs working with aprox 80w (480/6) ea would generate 20% of heat at the worst case temperature. Then I made: 0,2*(80)=16 heat watts and sized the dimensions of the heatsink. I've reached that a 8'' x 8'' heatsink would handle each cob. Is it make any sense? Thank you. PS: my setup is: 6 vero29 3500K B on a HLG 480w (54V) driver.
