Why hello there,

Well recently i just built a PC,
Instead of using the Stock fan from the Chipset, i installed a CM GeminII, and had two fans mounted on top of the GeminII.

We all know that GeminII's a Poser and not a Performer but it works well as it's a Passive Heatsink which ...well.... better than stock (and Cheap).

So here's a thing that i'm having problem with.

There's a three-pin head that reads the Fan's RPM and Data which can usually be found in any Stock Fan for the Chipset, and three of them is found on my mobo.

And since GeminII doesn't came with any Fans when bought, we'll have to mount two normal fan(120mm or any size and so on) in order to have cool air to blow directly to the heatsink and the mobo too.

But Normal Fan doesn't come with the three-pin head that gives the system the data of the fan, so in order to get any data of the fans, what should i do? What should i'll be looking for? Is there an alternative?

Hope to hear from you guys soon.
Thanks in Advance

If you want fan speeds, then you are going to have to buy 3 wire fans. There's no way around that that i have ever heard of, and i mess with hardware a lot.

now i learned a new thing, never knew they exist, thanks

A fairly high percentage of new fans are 3 wire ones.
