Silent Sine Wave Output UPS

Hello, I recently purchased a SRV1KI (APC Easy UPS On-Line SRV 1000VA 230V) and the fan is always running, regardless of battery charge and/or load.

 

Speaking with support, they confirmed that the fan on the SRV models never turns off, and the noise is unbearable in a home environment.

 

I want to replace it with another model that turns off the fan when the battery is full and the load is light. Would a SMT series UPS be silent, and at what power? Can I get a SMT1000IC or do I need a smaller SMT750IC for fanless operation?

 

Thank you very much!

I have a SMT1000C sitting on my desk and I rarely of ever hear the fan run.  I also have a SMT1500C and I do not hear its fan run.

Thank you very much, I recently returned the SRV1KI and received the SMT1000IC and it is absolutely silent (only some minor humming noise that I can hear if I put my ear next to it)
