Yeah, I was thinking you'd get two fixtures like the ones I'm running but forgot about the active cooling. You could probably get away with a single big 200mm PWM static pressure fan to draw the heat off of them. Those actually look like decent sise heat sinks. With the build quality of ShenZhen's products they might have overcompensated for safety but at the same time they do love efficiency so they might be dead on spec. Probably better not to risk it though. I don't know enough yet about COBs to know exactly how much heat sink surface area would be required. Been a long time since I've had to do any electronics calculations. All my training is still bangin around in my head somewhere I just need to read through a book or two and it'll come back. I don't know where I've got my little electronics dictionary stashed or if I gave it away.
I was playing with the idea of liquid cooling.
Yeah the individual heatsinks look decent and may work on its own but as you said its better not to risk it. Afterall you’re doubling the wattage so it would emit a lot more heat.
If you’re gonna do all the work buy the parts individually, i’m sure you can get a better fixture and it would cost less.
