FSB - Front Side Bus
It's the frequency used by the device ( CPU, memory, MB-CPU slot ) .
The best is to read first the MB manual, it explain a lot about memory, types of memory , connectors etc.
In your case, the best match is when the CPU , the memory and the MB run at the same frequency - 1600 MHz.
For CPU find the producer page and read the specs.
Same thing for the memory producer, sometimes they specify a different voltage than usual for certain frequency.
Try to avoid the water cooling, better invest in silent but powerful fans, 12-14 cm in size.
Look for the Air Flow ex. : http://www.scythe-usa.com/product/cpu/034/scsk1000_detail.html
You will have to dismantle your case to install the fans, especially the front, depending on the age of your case, in front must be a place for 9-14 cm, side 8-12cm, rear 8-12 cm.
If you could find, buy a small fan controller, 3,4 in in size, you will be very happy in the summer...lol.
Try to find fans with 4 pins at connector, that will allow to MB auto control, especially for CPU and System fans.
Also is a good idea to make some holes in the upper panel and install also a 14 cm fan, to blow the hot air up.
When you begin to install Win, after the last restart, but BEFORE Win want to make updates, install the software from the MB CD ( MB drivers first, Video second, audio last and reset after each installement).
LOL...you have a LOT to learn to master your toy...
