@WilliamRamsey My understanding is that 24v would be more standard and has some advantages over 12v https://www.waveformlighting.com/home-residential/advantages-of-a-24v-led-system-vs-12v

Wondering if you should choose a 24V LED system over a 12V LED system? We list 4 advantages of 24V LED systems here.

@WilliamRamsey There hasn't been as much experimentation with 24v fans

@mark_ungrin suggested the Sunon MF92252V1-1000U-A99 which looks good and inexpensive for scaling to many fans. I haven't tried these yet, curious about noise levels at different voltages https://twitter.com/Mark_Ungrin/status/1620215377044336642

“@JimRosenthal4 The Arctic P14 fans have been the standouts so far in the 12VDC category (not my find, that was @robwiss), in terms of both cost (the 5-pack is great value), power consumption and noise. The best one I've found at 24VDC (in Canada) is the Sunon MF92252V1-1000U-A99, via Digikey.”
