LED Heatsink

[Airphotog]

A question for all of you LED gurus. I am thinking of putting 48 LEDs on my 48" 90. I am looking at using qty 2-3.5" x 44" heat sinks with fans. Anyone see any issues with this setup?

No one ???

Should be. Fine, I am running 48 LEDs on 2.5 inch c-channel with fans over a 75 gal. no heat problems but may add more LEDs down the road.
