Apack ZeroTherm BTF80 Copper Heatsink Review

The all aluminum Apack Zerotherm BTF80 is a 458 gram heatsink which is designed to function with socket 775 Intel Pentium D/Core 2 Duo, and socket 754/939/940/AM2 AMD Athlon64 processors. The heatsink is even rated for thermal loads of up to 140W! The Apack Zerotherm BTF80 is identical to the Zerotherm BTF90 heatsink except for its all aluminum construction. Both heatsinks resemble a butterfly from the top down - a design choice which is likely to cause wide skepticism with North American consumers. If the insect shape makes you jump to conclusions on the effectiveness of the heatsink, you might be surprised to know that the Zerotherm BTF80 actually performs fairly well.
