i recently laid my hands on a working but empty 1u chassis that was being disposed of (a supermicro sc813m), to hold the last few drives i can add to my "backup" server. hey, can't beat *free*, right? anyway, bought a used power board off ebay (a supermicro JBPWR2) along with an SFF-8088 to 8087 bracket, fished out a breakout cable and a fan splitter out of stash of parts, assembled the beast... tested it in a large room -- hey, not too noisy... and racked it.
when i turned it on again, what the...?!? it's noisier than my 2u jbod drive array! (that quantum dxi6500 i posted about some time ago)
i quickly found out the 40mm fans (FAN-0061L4) are rated at 44db each, so 4 times that... either i get quieter fans or i put some in-line resistors that came with noctua 120mm fans i bought for my 4u boxes (norco 4224 & rosewill 'l4500). For the fans, i know the FAN-0100L4 would fit, though it appears to be costly to purchase in canada and only drops the noise level 10db. another fan that could be an option (Sunon 40x40x20mm 3 pin fan #KDE1204PKVX, https://www.amazon.ca/Sunon-40x40x20mm-pin-fan-KDE1204PKVX/dp/B006ODM76C), as it is cheaper & *much* quieter, though not sure it could really be used with a at supermicro 1u chassis like mine (20mm deep instead of 28mm, 10.x CFM instead of 16.3).
at the moment, am leaning towards using the resistors (cheapest known solution), but i have to make sure it's safe to do so.
or is there another option i'm missing?
thanks in advance!
