if you are really worried about it, you can always get an auxillery fan and plug it into the power up plugs in the back of the receiver.. that way, it only blows when the power to the receiver is on, and shuts off when you power down. i have contemplated getting a small fan for my onkyo, but i rarely push high volumes for extended amounts of time. it does get warm, but not excessively so.
