Just a question, why shouldn't I exceed 12v 2a? What does it mean?

If your fan is measured in watts (which I think most pc parts are) then Watts is amps x volts so if it was 10 watts and the fan is 12v that would be 10/12 which would be 0.83 amps so in total it can’t be above 2 (adding all your fans up) or your going to be overheating the cables/board etc and you could cause damage or start a fire (This is an explanation of how to work it out It depends on your particular fans)

Can you plug a normal fan into the cpu socket?

if you are on about the three pin fan then yes

Can i plug 3 pin fans into the hub?

I am sure it fits for 3pin fans

where do i connect it on the fan pin or CPU fan pin

It depends on your system and you needs, although the adapter is marked as 'Cpu' + chassis the CPU connection is the master fan-the only one that can report rotation speed-if you plug his into the CPU fan header and into the Cpu fan controller socket than all fans will be driven the same as this fan, if the CPU fan has a separate socket then you can plug this adapter into a chassis fan socket but all fans will get the same voltage/PWM as the first. If you try and mix PWM (4 pin) and voltage controlled (3 pin) on this adapter then some fans will end up not being correctly controlled.
