I have a dual redundant PSU set up in my Supermicro SC745TQ-R800B, The PSU's are PWS-801-1R. I only use one of them at the moment, I may use them redundantly but think there is no need and will just keep one as a spare outside the chassis (It alarm's if you don't have power to one)
The issue I have is noise, each one will sit at 22 - 25 degrees when under load, but the fans lowest idle speed is around 5000rpm, which is what they constantly sit at.
I'm wondering if there is a way of modifying these so they spin a bit slower, I'm not thinking an inline resistor or anything, I wondered if there is a potentiometer that can be adjusted or anything flashed to it's logic (It must have logic as it reports status to motherboard).
I've already swapped the 4 central fans and rear fan to the same as what the "SQ-Superquiet" version use. I would have gone for the SQ model, but the PSU is way overkill and rated something silly like 1200~1400 watt!
I don't really want to go purchasing new PSU's either as it's a brand new chassis.
Not sure if anyone has done anything like this but thought i'd ask.
