CRJ DC 12v Power Supply: https://www.amazon.com/CRJ-Power-Supply-4-Pin-Computer/dp/B071FNN9W7/

I have several fans left over from old PC builds. Most are Noctua, NZXT, and a several Corsair. I also have more than enough extensions and splits.

but I'm not sure how many fans I can chain to this...

120mm: https://www.amazon.com/gp/product/B00KF7R49S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

140mm: https://www.amazon.com/gp/product/B07655KF5C/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1


thoughts?


Edit: I see now. 120mm is .1a, and the 140mm is .13a

Pretty easy to figure out.

12V 1a power supply.

The 120mm fan you linked is .1a.

1 amp power supply. Fan draws .1a.

10 ;)

All I see is 12v listed in the item description. Where do you see .1a? I must be blind.

Your power supply is rated for 1A current so probably somewhere between 1.5-5 fans depending in their draw. I have seen them from 200ma to 700ma and the listings you posted didn't say. I would look into a beefier power supply with a higher current ratings if you want to run several, or research the exact fans you have to see their current draw.
