2 pin fan header?

[mightytech]

So i have an old fan in a box of legacy parts that my uncle gave me, it is 120mm, but it has an odd looking header thats 2 pin

Does anyone know what this is for?

Looks like a fan without the ability to tell the RPMs..

[Godlygamer23]

Two pin fans cannot monitor the RPMs.

but where do you plug it in? XD the header is so odd...does it fit in a normal 3 pin?

Yes. It'll work in a 3/4 pin header.

I just checked my really old nVidia GPU an it has one of those on the fan.

So it's a really old fan header for a graphics card or something else.

Most likely it came from a power supply. The fans in power supplies, when they aren't soldered in, use that type of connector.

Oh haha, well point is, it's really old.

Can't transfer any info to the mobo or anything since it just has the power connectors.

yeah, like i said my uncle gave it to me and he has been doing tech stuff for awhile so i had no clue, he didn't even remember what it was for.

There are 80mm desktop fans though. And they are on many video cards.

i think i have a stack of 80mm fans. They are super thick and sound like jet turbines. They also function as an air conditioner.

most likely a power supply fan, my coolermaster 500w has the exact same fan connector
