Are they screamers?
I got a useful 12V 50A PSU, but it's a total ear-bender, with a fan going at 4K all day long.
I tried to kick that fan into touch, but discovered the fan is tied to a cunning monitoring board in the unit, so a quieter one doesn't work - it will run, but the unit doesn't power up, as it thinks the fan is duff.
These things were designed to run in server rooms and old-tech server designs paid little to no attention to noise concerns - and I suppose that's handy, as a lot of the older but still perfectly useable stuff is being turfed out, to be replaced with quieter and more efficient gear, so means there are bargains to be had.
Not expecting them to be quiet but there is a big section on RCgroup.com about modding these and it gives the pinouts for auto fan speed so hopefully bearable. They came from a decommissioned IBM blade server and are probably way overkill for anything I will ever need but they were free so would have been rude not to.
