I hear you - my AVR and speakers are 10 yrs old so I don't like to trash stuff. But when I bought it I knew of the fan noise issue so I went into the purchase knowing a repair might be needed if I mucked up something. It was super easy, just like the inside of a computer, unplug the fan and pull it off the plastic clips. No hassle.
