Ah ok, thanks for the heads up, I'll just use the tuniq for all of it then

. I added this fan set to use as case fans:
Newegg.com - COOLER MASTER R4-S2S-124K-GP 120mm Case Fan - Case Fans
There are two things I'm not sure on though. One is that I have a pre-built, so the OS came installed already. Since I'm getting a new motherboard, will I have to get another OS (7 comes out in a few weeks, so I would get that if I have to)? I know I'll have to reformat, but C:\ is actually a partition of D:\, which is what the recovery disk is stored on. If I format, do I just format C:\? I do have 3 recovery discs (actual cd's), do those actually install the OS if I format the whole drive?
The second thing I'm not too sure on is my PSU. I have an Antec Earthwatts 500w, it's working fine for me now, but I don't know if it will be ok when I add the extra fans (also maybe a fan controller and if I eventually OC a little).
