Help with heatsink

i'm doing a cob built with cmx22 (70w each cob) and i'm searching the cheapest way with the heatsinks..

Pin fit are too expensive compared with artic apline 64..

But don't know what can happen if the fan turn off..

And the other dude the artic apline 64 pro is able to disipate 70w?

Thanks

arctics can do way over 70W theyre like little helicopters. and yes if the fan dies you could lose a cob, but people say they are pretty reliable fans

I would just use a 12V 1.5-2 amp wall wart type power supply.

Hi, and how i can do to connect the fans to that driver? Should use any connector type? Or can use a waggo?

wagos are fine, wirenuts are fine, you can twist and tape them with electrical tape even. the more time you put into wiring the more solid it will be, and you want your fans to be solid

You seem pretty set on the Arctics, but here is a tool for Heatsink USA if you're interested:
