I was somewhat bothered by how loud the 7205's fans are also. It seems like its at its noisiest when i first start it up then it slows down. I usually keep the temp in our theater room around 75, It does get louder if I dont turn on the AC though.
If your not concerned about voiding the warranty I suppose you could try swapping in some ultra quiet computer fans. I dont notice it when a movie is playing of the tv is on so its not really a problem for me unless the sound is turned down. If you change the fans out let us know how it went.
