We all want the best cooling we can get when we decide to overclock our systems. People spend over $50 for a good processor heatsink and plenty more on case fans. The one thing people almost always overlook, is their graphics card. There's a lot of GeForce 4s out there that come with a rather cheap HPU heatsink/fan, and no ramsinks at all. Luckily Thermaltake has realized that people need cooling products for their graphics card too! Today we'll be checkin' out a ThermalTake G4-VGA copper cooler with ramsinks on a Vision Tek 4200 SE.
