fan noise

I recently had 10 ETC ColorSource PARs installed in a small chamber hall. I thought the result was wonderful. But the users in the space are complaining about the fan noise. Are there any LED PARs (of this quality) on the market that don't have a fan?

Looking at starting transitioning some of our lighting to LED. (Why should I be different?). I wanted to start with our washes and am considering the Rogue R1 and/or R2 as possibles. But I'm frightened by the large fans on the back of them. Our theater is small - 126 seats - with a 14' height...
