I bought a UPS a year back to use in the server rack.
What I did not think of was the noise level. I think I saw the specs and saw a fan, but didn’t think it would be spinning all the time, or to be so loud.
Well, I was wrong and the fan was a bit louder than I could accept.
First thing I tried was the easy one. I just swapped out the fan with another one I had, a Noctua. Known for their silence.
That worked for 5 minutes, after which the UPS decided the fan had stopped and turned itself off. The fan WAS running, though.
Apparently there must be an incompatibility with the RPM-sensors – perhaps.
I am a little bit of a tech-freak, and as I also work in IT, I have become accustomed to using rack cabinets for containing all the techy equipment I’ve got to run in the house. It is practical and keeps everything quite tidy.
After acquiring a few pieces of what I needed, I had to make an actual rack to house the equipment.
