To be specific, I'm talking about5E2000iUSB. There are not many options of UPS in my country. I decided to go with this model, but can't find much info about it on the internet. One thing I read couple of times is that its fans being really loud. I'm okay with fans spinning hard when the UPS is running on battery, but do they spin even when the UPS is getting the power from the wall?
One other thing I would like to ask is that can you permanently mute the beeping that occurs when power goes out? My current - soon to be replaced - UPS has a very annoying, really loud beeping when the power goes out. And the only way to mute it by physically pressing a button on UPS, or having a computer connected to it while its software is running. So if that computer is turned off for some reason, or if the software is not running and I'm in another...
