One week after installation, the cooling fan started failing. It made a high pitched screeching noise and then stopped spinning. Rather than send it in for repairs, I replaced the fan myself. It has performed very well since the repair. I have no other complaints about the amplifier. It has a very clean and powerful sound and seems to be a great match for my Boston Acoustics SR95 6x9's.
