Having problem with fan connector

Hello guys,

My motherboard is a Gigabyte H87-HD3.
The fans in my case are molex, so they were running 100%.
I bought these from Amazon. But im so confused.
Where do the plug in ECT.
I have a feeling that i bought the wrong product.....

You need a Molex to FEMALE rather than the male that you have.

Something like this:

Were running 100% sounds like you want it past tense but adding those adapters will still only allow fans at full 12v. I hope that's what you wanted if not then you want some of these or a fan controller. 5 Pcs 3" Fan Speed Reduce 3 Pin Power Cable Adapter for Desktop PC: Electronics

Windows 7 Home Premium x64 you want something like this, you plug in your fan and then the other end in the molex Cable, there are 5v,7v that are the most common ones.

I use this one ModMyToys 4-Pin Power Distribution PCB - 8-Way Block Products Model: MMT-PCB-4-83 [MMT-PCB-4-83] :, ... sleeve it and they will come hooked up to my psu, and then I use 5v adapter plugged into it
