Now, I better look into finding a way to silence this new UPS fan which

Some new UPS systems are designed to have the fan running all the time.
I don't think it's a good idea to stop it...

Right, I suspect it is meant to be running all the time, at high speed when
running on battery and low speed at all other times. This is a 2nd hand HP
T1000 G3 I bought cheaply, because many of the new entry level UPS appliances
being sold today are not fit for human consumption, judging by user reviews.
Yeah, I found that out. One of my UPSs crapped out after a power failure
a couple weeks ago, then I realized it's from 2006...
I did some looking around (I had an APC) and all the APC branded crap
you get in the stores are cheaper, inferior options. I found out the
BX-prefixed models don't even have proper AVR (they only correct when
the voltage drops below a certain point, they don't do anything in an
overvoltage situation. The BR-prefixed models are like the old UPS of
lore, they offer true AVR for both undervolt and overvolt situations,
and the one I have even has an option for an extra battery pack for
extended runtime (BR1500G.)
Basically anything in Best Buy, Staples, or similar stores is guaranteed
to have the consumer BX model junk.
APC gave me a reseller that sold me the BR1500G model and it was about
$50 more.
And as a bonus, it still works with apcupsd. I heard some newer APC
models are using some new proprietary communication protocols. Never
seen one in practice though, I wonder if that's the consumer junk I was
reading about.
