Nope. Because I'm working on a clip-on/bolt-on to mount double 120mm fans to the side-flows.and now I can finally close this thread
You're on your own for the electronics, unless I can remember how to trick the ports into providing power. Then you can use two of these ramped down to about 32-36V. (They're what I found that's easy to order off Amazon.)
Remember our airflow target is ~90CFM, but if you don't provide for the entire side, you either cook the PSU or you cook the POE board. Definitely better fans out there for it. But shortening the ramp to wedge ~100CFM from 242x121mm surface into those side vents at a <4" total thickness comes with VERY high static pressure demand (which means: loud.) And 48VDC is generally only used for "noise no longer matters" applications.
Long ramp 48VDC, probably would go SanAce 9G1248M401 (but MOQ is 60) for 59CFM @ 29dbA/ea.
Short ramp 48VDC, definitely need more thinking time.
Running off 12V, anything 50CFM or above would be fine, but you have a STRICT limit of 0.45A @ 12V off the board headers. (5.4W!)
I'd much prefer 24VDC, because then you can use Mechatronics G1225S24B-FSR's. 54CFM @ 26dBA and $11/ea. Just an excellent impeller design on those. 1500RPM with a pretty flat static pressure curve and 54CFM? Sign me the hell up.
