Do you offer a passive cooling version (no fan)?

LOL @ those other answers. Modern LED grow lights are often cooled passively. No 25mph winds or heatsink the size of Delaware. *eyeroll* (I have 600w of LED for my tomatoes and peppers, manufactured by a famous company, all passively cooled. However, those go through extensive research and development. This could probably cool 5-25 watts of LED without a fan, but heatsinks like these are specifically designed for air to flow over them. The tight, tall fins just pass heat back and forth without air movement. A much different design of heatsink would be needed for 50-100w. You can get a very silent 80mm fan for not much money, $9-$16. Brands like SilenX, Arctic F8, BeQuiet!, or GeLid are options. Then you just need a 12v 1A power sully to the fan.

Can this also fit a 150 watt led chip?

This heatsink fit 20W/50W/100W/120W ,If use for 150W we suggest choose this 2 models will better: http://www.amazon.com/dp/B01CTZ8X8Y or http://www.amazon.com/dp/B01D1J1JFQ

I prefer something with passive cooling (videography) because fan noise is not acceptable. How many watts will it sink if fan is removed?

As already mentioned, air movement accross the fins is what removes the vast majority of the heat. And, there are some extremely quiet fans available. They spin slower, so less noise.

Do you have an option to purchase without fan i already have 120v 80mm fans just need heatsink, lens assembly and screws.

I am sorry, Our inventory in amazon wareshouse all include the fan.
