I currently have a APC Back UPS Pro 1100 that is louder than my computer. There are no fans or anything in it, but it has coil buzz that is kind of loud. Any ideas on how to get rid of it? Acoustic foam does not seem to do much of anything to get rid of the noise. More solid materials like wood seem to do a better job to block out the noise. I have considered building a box for it, but it would overheat without vents I think. With vents, noise would escape. Anyone have an idea if it would work without vents? What kind of temps are these things able to take? Putting it in a closet may be possible, but would require long extension cords and I don't like running them all over the place.
