Got the white running and I left them on over night to take some reading. The room temp was at 26, driver 58, side of heatsink 32, middle of heatsink 39. The heatsink when touch just feels warm. The driver won't burn you but she is warm. But that's running it for 10 hours on max output. Even with the blue running and no fan... I don't see a problem with these heatsink.
 The 6 leds on the left has 60 degrees lense on.  The pot is just temp until the unit is hooked up to the Apex. Measured the current for the 3 strings. 678, 670, and 660ma.  Driver mounting location. They got pretty warm after the overnight full power test. Any suggestions on keeping them cooler? Sent from my GT-I9300 using Tapatalk

Very interesting build. Glad to see it coming together. This is somewhat similar to my build on a slightly smaller scale.
I was concerned about heat on some of my channel but after investigating (mostly on RC) it appears that all the LED gurus have indicated that you only need to start worrying about the heatsink temp if you can no longer touch it safely....and I'm a far cry from that as are you.

I'm sure someone who uses them probably has a better idea, so I'll just throw this out there ...

How do you feel about mounting them away from moisture and cutting holes in them ? Then you could use little DC fans - they come as small as 25mm
