About a CXA3070 & Heatsink

Hi there!

Have been lurking forums last couple of months in order to do a CXA3070 COB build, and so far Im all for a passive cooling unit, and these are the 2 heatsinks I got aviable here in M3x1co:

Mod. C125 L: 14 cm H 5.8 cm Deep 12.5 cm
Mod. C150 L: 14cm H 5.8 cm Deep 15 cm


Or the Cree heatsinks:


LMH020-HS00-0000-0000081
L: 153 mm
H: 100 mm

LMH020-HS00-0000-0000061
L: 138 mm
H: 100 mm

Which one would you choose to pair up with a Mean Well LPC-60-1400? Or should I target for a 40W - 50W driver in order to keep everything cool without a computer fan setup?

Thank you for your replies!
