correct adapter choice for usb pc fan?

[k-grower]

hi to everyone, i´m currently making second fogger setup (230v) though this one is for climate and not for roots, i´m not sure about correct amps for this project so i have many choice to offer to help me out,i am also baffled about the ac/dc markings as the fan is dc
and some of the adaptors have dc on and ac/dc on lower info. the space is homebox xxl tent. share your thoughts about the build

and as water reservoir i´m planning to use couple of gallons bucket whit lid where is drill holes for fans to push air and from the lid a hose to front of oscillating fan, and for fogger i´m going to make floating basket from net basket and neoprene what will float inside the bucket.

any of the adapters you linked is good. I'd go with the 5V 2A one to make sure I got enaugh power for more devices in the future on it.
but you could get 12V fans (and 12V adapter to run them too) that run faster. you can even find cheap fanspeed controller for 12V that will control them to the speed you want them at..

thank you from input, i were little worried do i get it working as i all ready made the order, i thought no one is gonna reply for me here.
i found after making this topic that someone on other forum suggested not go over the fan specs amper as it could shorten the life of it, so i decided to take that 0.5A adapter.

after i read your suggestion of the speed controller i made some research and decided to buy proper gse gear whit both humidity and inline speed controller in 230v current, as i needed inline fan controller also.
i hope the correct humidity will increase the production of flowers as in winter the RH is about 30-35% here north.

Voltage specs is what you don't want to go over. The device will take as much amps (or mA) as it needs. But 500 mA (0.5A) should be enaugh for your project.

good luck!
