That's right! It was Weapon heater cores that were the best performing units out a lil while ago. I guess for the average system his is still best and probably one of the nicest if not the nicest looking heater core out there. Unfortuantely it's really hard to contact him to see if he's still producing them with his custom built shrouds.
I guess his was the best considering dual 120mm fans. But I guess it's what your needs are.
Dual 120mm - Weapon's heater core w/shroud. ( I know there was some other company out there trying to duplicate it, I'll find the link and post if when I do unless someone else has it already and can do me the favor
)
Triple 120mm - Black Ice Xtreme III
Quad 120mm - Black Ice GT Extreme 120.4
Please correct me if I'm wrong.
