Total Weight: Swiftech - A Heavyweight at 789 Grams!
The fact that a heatsink's cooling capability and efficiency are closely related to its weight is due to the material used. Silver and copper are the best
AMD's guidelines only allow a maximum weight of 300 grams if the cooler is mounted on the socket with metal clamps. However, the Swiftech MC462 is not mounted in this conventional way but screwed directly onto the motherboard. Because the Silverado weighs 416 grams and is held to the CPU with conventional clamps, the fan may not be mounted during transport.
