"Once considered the ultimate in geekdom, liquid cooling (also known as water cooling) has become almost mainstream. For those pushing the envelope, there's high performance (and high cost) kits from retailers such as Danger Den, DTek, or Swiftech. However, those kits usually require either a great deal of patience, or experience, during installation. For those less schooled in the art of exotic cooling, your choices are fairly limited. While there are no shortage of pre-fabbed kits, both internal and external, marketed at the novice, these kits usually forego quality to make themselves as easy to install and user friendly as possible."
