PC Fan Wiring Help... Plz

[TokemonGo]

Hello all,
I'm a long time reader & soon to be first time grower. Although I've read several threads on PC wiring, I've ordered a fan that's a little beyond me & I'm hoping the more experienced members can give me a hand.

The fan has 3 wires coming out of it, instead of 2. One blue, one red, and one black. So, first question, do I ignore the blue wire and only use the black and red one? Or do I need a diff kind of power cord/adapter now?

The fan also is labeled as 1.6A, which I didn't notice before purchase. This appears to be alot more than most PC fans I saw when reading. I read somewhere that power cord/adapters should be rated at least the Amps of ur fan + 20%. Does this mean I need a power cord/adapter rated nearly 2A?

Thanks for reading through. Can't wait to here your comments & get started growing & finally get a grow journal going myself

the blue wire is for the rpm sensor if you have it hooked up to a computer, disregard it. As for the adapter I believe you are right. Personally I am using an old computer power supply to run my PC fans in my growbox. It works great.
