Besides the up n coming mechatronix pin fin giant cylindrical heatsinks, do any of these designs look adequate to passively cool an 100w Luna100? ![IMG_20161103_160848~2.jpg](/data/attachments/2922/2922060-d346c00f8341f8713b7bd4630eaeb440.jpg)

Am really liking these black ones. They are easily 90% lighter than an equal sized aluminum heatsink. I can get some aluminum that are approx 6"w × 5"d × 6"h and shaped kind of like ll¥ll and fairly heavy. or some that're roughly 6x6x3 but i thought copper was better option. whatyya say anyone? please feel free to be critical if necessary.... thanks
