Thank you for taking time to respond to my question, you're a life saver.
But I have two more questions if you don't mind, my first question is: are you sure that the first two are case fan headers?
There are 4 case headers attached to the back and one fan hub power controller (The ones you showed me)
And these are the original two that I showed you
Are you sure these two are the same thing? They look different (Sorry if the pictures aren't clear enough)
Question number two:
I have no doubt that those are cpu power plugs, but there is only 1 8-pin cpu power connector, and there are 4 4 pin cpu power connectors, each pair consisting of 2 4 pin cpu power connectors.
So if I plug in one to the 8-pin cpu power connector, there will still be one dangling around, is that ok?
So sorry about the question overload and long sentences, I am just really desperate for help, thank you so much.
