Small, light-weight heatsinks will have more trouble dissipating the heat from 10w emitters so you'll probably have to continue using fans.

Ok, I thought by Al you may have meant AI as in Aqua Illumination, a heatsink from the company that makes LED fixtures which you used in making your DIY. So how thick or heavy are these bars? Some photos, dimensions etc. would certainly help me visualize what you're talking about. The new heatsinks I have are advertised to work without the need for fans as well and they've been doing the job on the center row of lights for a couple of weeks now. So if I were to consider what you're proposing/using, I'd need more info. Where did you get them?
