What's that in active cooling ,sorry really bad at math
do you fell the LSB9980 passively cool will work for the build?

LA ? area right ?
I think there might be one here in the Sf bay area < ill look
here it is ;

There will be many Mechatronix heat-sinks that should passively cool a 3590.
1x CXB3590 @1400ma (56% efficiency) has 22 heat/w.
Assuming 120cm²/heat W, 2640cm²/ or 264000mm² (Total cooling surface/Surface area) should be all that is needed.
Like the look of these two:
LPF8668-ZHC- 68849mm²

LPF11180-ZHE-116830mm²
http://www.led-heatsink.com/seepricesandbuy.php?subcate=625
Hopefully they can do a clear version (no mounting holes) or even better CXB3590 mounting holes.

yes like the look of them! going to ask what might be a stupid question but dose it matter that they are coated in black? and not bare..
its not "coated" its anodized, which provides better heat dissipation, cause of aluminum oxide structure . while some think black is better for black body heat radiation, its really insignificant.

I'd want anodized , no tarnish & hardens the surface of the AL
Thank you fell they can cut a ton of weight over one 36 to 48 sink and save on cash

My guess is that makes them a bit better at shedding heat.

what's better thick rods vs thin fins @ heat conductance ?
don't know if that's the right term to use
the heavy duty look/feel to the rodded ones I do like

Anyone tested them?
The lsb9980 specs say, 139261.22mm2...which is 1390.6122cm2
(1390.6122sqcm avaiable on that sink) ÷ (115sqcm per heat watt for passive) = ~12 heat watts that sink can handle.
At best you are looking at 3590's@700ma for those coolers. Half of what your plan was for, and will not work with the original build we talked about.

gg and supra,what do you think of this for a 4 cxb3590 1050ma passive?
very cheep and look cheep but i order them for testing.
10752sqcm(i assumed 4mm base) 55 w of heat,so 195sqcm per watt of heat
they look cheep but i think they will do the job

CDIWeb also carries the Mechtronix. If you call Whit Allen, he can give you recommendation on cooling. He was the one that hooked me up with the Coolbays (470 watts max) and checked cooling capacity for me. He has also gave me great pricing on drivers.

OK thank you diy talk went well that's why you are the go to man as i start to order parts list.. what would be a good alternet round sink

Iceman the pinned heat sinks are designed for tilted applications

So they'd be the Dolly's tits for vertical, wouldn't they?

I still think a wall of the 4' redbird led strips would be awesome for vertical or side lighting. I just can't afford to play with these and the monster COB's I have now. So simplicity and power win.
