Hi guys !
Very interesting stuff in this thread ...again
I'm about to build my own pannel and I'm a bit worried about the heatsinks I've just received ... I plan on using them for passively cooling CXA3070AB from 700ma to 1050ma and I'm concerned about them efficiently doing so.
Although they're said to be able to passively handle 70w of dissipation (see here: http://www.ebay.de/itm/Alu-Kuehlkoerper-fuer-10-120-W-Watt-LED-Chip-Heat-Sink-DIY-Fluter-SMD-Flutlicht-/111362015923?ssPageName=ADME:L:OC:NL:3160) the current discussion of this thread and some warnings that have been sent at me already might push me to reconsider ...
Of course, I could just mount a cob on it and give it a try but I will use a single driver to power 4 cobs (HLG-120H-C1050B 155.4W 1050mA 74-148V) so it means I would have to mount all 4 cobs on their respective H/S and wire up the whole thing before I can perform some tests ... when the H/S fails to handle the temperature dissipated by the cobs I'll have to dismentle the whole setup and start over.
That's why I'd like to know what you think of those heatsinks before I proceed ... If you guys think they'll not make it I'd rather get some Alpine 11 plus CPU cooler than build everything using those ones and notice they are too weak ...
Once again your advices might spare me a lot of hassle !
