NEED HELP on heatsink

It is a 40cfm 70mm fan and I am planning on making a 6x50w 4x3500k 2x6500k. Now I'm curious if ya'll think this heat sink will work for this application.

Don't know all the dimensions. I'm assuming 70mm tall because that appears to be a standard 120mm fan. So if it is 120x70mm with fan then you're fine.

It is a 70mm fan. 70x70x44mm that's the size. The cpu those are meant for is 65watts. So 120x70mm heatsinks are a sure fire way, Thanks.

Is the price difference all that much to justifie a smaller heat sink, or do you already own them. You can get artic 11 120mm attached to a heat sink from eBay for around 15 dollars shipped I believe, when in doubt always go with the bigger size.

i tend to find that doubling the power rating over the actual application power dissipation does wonders to a circuit. but if you're only running the 50w LEDs @ 30w then these would be great. i wish manufacturers would lower the price of the coollant filled heatsinks they make for these power LEDs.

side, have you seen active cooling? GE is producing these little films that move air past the LED very rapidly. i think they're silenced ultrasonic transducers that move a diaphram up and down.

i dont quite understand if this just makes the heatsink more effective or if it replaces it....
