OK, so a lesson on Pc power management:
You may notice when building the computer that the PSU has a large master kill switch on it, but then has no on-off button. The way things work is that the PSU supplies just a little bit of power to the motherboard at all times. This runns things like BIOS, the clock, and a few other odds and ends. The power button for the system also plugs into the motherboard, which is then routed to the PSU. If the motherboard is in a state that it is not ready to POST (power on self test), then it will not relay the power on command from the power button to the PSU, so the entire system remains in an off state.
If you jump the right pins on the PSU's motherboard connector then you can bypass all of this and get the PSU to turn on... but I advise against this unless you know what you are doing... and you are not qualified for that quite yet.
The fans will typically have a 3pin or 4pin fan header. On your motherboard you will find 1 4pin PWM fan controller for the CPU fan, and typically 2-4 other 3pin fan connectors which may or may not be controlled by software to be able to select a speed. The manual will have a page that points out where you can plug the fans in on the board.
The other option is to get a fan controller where you can plug all of your fans (except for the CPU and GPU), and then manually control their speed (and noise) to what you want. I like to run my system at a constant RPM because I occasionally do recording and it is much easier to filter out what little noise the system makes if it is constant rather than variable, so I have all of my case and GPU fans (because I am using a rather odd GPU cooler this is possible) on a manual controller, and then I set my CPU to a specific speed unless it tries to go thermonuclear on me. While this works great for my setup, most people will want to use a more intelligent controller as found on most motherboards.
Note that while a 3pin fan can plug into a 4pin slot, a 4pin fan may not work properly in a 3pin slot. It may work, but you may not have any control over the fan speed.
None of your fans will work until you can turn the PSU on, and you can't do that until your motherboard will POST, and that won't happen until you have ram... so it sounds like you have a bit of time to wait.
I am not all that noob-ness? lol to what I am doing I am more or less on an adventure of figuring as to how things work and where everything is suppose to be plugged into, which I have tried fallowing the MB user manual which helps a heap ton!.. cause I know not all MB have same lay out umm far as the fans go perhaps I posted a picture maybe that will give you a better idea as to what I may be speaking of??
