Home Crown Amplifiers

My XTI4000's fan runs fast (at its highest speed) all of the time......

(continued)....although the amp seems to work well.
I own four xti4000's in total and the other three have fans that vary speed. The unit in question's fan did "vary speed" when I first bought it...it just started running at full speed a couple of years ago.

The units that I have are first generation and all have had the ribbon cable / front panel upgrade.

Other than the fan noise, the unit seems to run well.... I use it in one of my long-throw outdoor racks thus the fan noise is not an issue..

Should I be concerned??

Please advise.

    I think you just need to stay alert and keep an eye on it, but as long as it is working well, you should be fine

    The operating mode on the xti fans are configurable. They can be on 'Auto' OR 'Manual'. Have you tried a factory reset?
    If the mode is auto and they are on full, and your other 3 amplifiers are not operating like this, I think you should be concerned, because something is definitely wrong.
