hey guys. Citizens are cheap and effective. I want to spread out 10-12 of them over a 2x5 area but finding 100mm pin fins is impossible nowadays. Anyone have any ideas on a good cost effective way to do this?
 
WHEre would you suggest getting those? They have fans attached to thiuhnright. Passive is definitely what I’d want to use for such low wattage.. No need for active.

Did you check Kingbrite?

There's always Arctic Alpine.

Also, Jerry would be a good idea, but the fucking shipping costs are so outrageous. Maybe if I got everything from him it might be worth. Drivers, citis, and heatsinks all in one.

Buy a ordinary CPU cooler, it's very cheap, bigger is better. Mine is GlacialTech igloo 1100cu with copper core ( cost about 4$)

Is that A Citizen COB? Where’d you buy those sinks? And remember I’ll only be running about 35watts... very minimal heat.
 
A lot of people overcool their cobs. It doesn't hurt anything but you only gain abit of efficiency. If u have a source for aluminum plate, at low power 2mm or so plate is plenty to cool cobs sufficiently. Just make sure there's some airflow around the lights.

Yeah but what size of plate? That’s the question. If I wanted to run 35-40 watts (1050ma) on citi12-12’s, how large of a plate would be needed?
 
I think I’ve found my solution. arctic alpine m1 PASSIVE is only $9 on jet.com if buying 10+. That would probably work out for me I’d think. I’m just curious if a 12-12 would fully fit snugly on that raised portion of the mounting spot on it?
