GPU cooler

Hai guise, Which cooler is the best for gpu? Acx/TwinFrozrIV/Dcuii?

Depends on what graphics card you're thinking of. Try google your graphics card, and find the best perfoming cooler for that exact graphics card. I use 660ti sli, with MSI's twinfrozr II. I like it, but I prefer Asus og EVGA's ACX coolers.
