The V8 is the stone in the shoe for Coolermaster, get the Tuniq towe as abully says, or Titan Fenrir, Thermakright Venomus X, Megahalems, Mugen 2 Rev. B, NH-D14, Silver Arrow or Archon. Those are very good coolers and much betters that V8.
Regarding the WC, if you don't need it don't install it. If your cousin's rig fried something was because he did something wrong.
