Answer 1

Assuming your PSU has a strong +12V rail, you would need something like this:

You are adding almost 3 amps load on the +12V rail, but since these are fans, their simultaneous starting current could be 6 amps or higher. You might fry a teeny-weeny PSU.

Hi,
You can do pretty much anything you want as long as your power supply is rated high enough. If it is, just keep adding Y-Connectors to daisy chain the fans.

- CFM = Cubic Feet/Minute: How much air is moved by the fan in 1 minute
DC - Direct Current - the Power supply in your computer turns wall current ( AC) (Alternating Current) into Direct Current
AMP - The Amperage draw - how much current the item pulls
Db - Decibel - the amount of noise generated by a device.

You have a 12 Volt DC fan pulling 1/3 of an amp moving 94 Cubic Feet of air per minute and generating 41 db of noise (which is not toooo loud - but not that quiet, either

Like colour wires connect at the same time. as an celebration, all red wires connect at the same time, and should be suitable to the precious (+) terminal of the flexibility provide. you truly are making issues complicated for your self. 8 followers and multiply that type of followers by technique of the present of only one, which could be 0.35 circumstances 8. to provide some room for issues, or to help the flexibility provide very last a touch longer, use 10, so as which will be 3.5 amps, so a 4 amp provide should be in basic terms high quality. you are able to flow larger than 4 amps, yet do not flow less than 3 amps. some thing else of the coaching, a #20 gauge cord, hook up style, or varnish coated magnet cord ought to do precisely high quality. The type of blades is incomprehensible coaching. The 40-one Db refers back to the noise factor of the followers. they should be truly quiet. the dimensions and hollow region is for mounting coaching and the gap mandatory for them to in good condition into.
