125W Thermal Test (°C) Noise Level (dBA)
*Heatsinks are ranked according to the 125W Thermal Test results column (rise over ambient temp.). Low temperatures with low noise levels are considered best. For reference heatsinks with variable-speed fans, only the high speed (12V) fan test result is included in the comparison sheet; more detailed results reside in each specific heatsink review.

With a 125W heat load applied by the FrostyTech synthetic thermal test platform, the Apack ZeroTherm BTF90 heatsink yields a very nice rise above ambient temperature at its stock fan speed of just 20.5°C, with 52.1 dBA noise generated.

FrostyTech Mk.II Synthetic Thermal Heatsink Test Results
Intel Pentium D / Extreme Edition & Quad Core class heatsinks tested at 150W
Intel Core 2 Duo / Pentium 4 /Celeron class heatsinks tested at 85W

Results based on readings from a 30x30mm copper interface die with 150W and 85W heat loads applied on the LGA775 version of the Mk.II Test Platform. Temperature results listed for each heatsink were calculated by determining the rise over ambient temperatures at time of test. Information on Frostytech's test methodology is available here.

For reference heatsinks with variable-speed fans, only the high speed (12V) fan test result is included in the comparison sheet; more detailed results reside in each specific heatsink review.

With a 150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal test platform, the Apack Zerotherm BTF90 yields a rise above ambient temperature of 21.8°C with 52.1dBA. The CPU equivalents of this test would be an Intel Pentium D / Extreme Edition or Core 2 Quad class chip. With an 85W heat load, temperatures drop to 12.7°C over ambient.

Key to a heatsink such as this is good airflow; the fan exhaust should always be directed towards the rear of the computer where case fans and the power supply can aid in the removal of warm air from within the chassis. The widely spaced copper fins offer little resistance to airflow and consequently a slower speed fan meshes nicely with the design.

The 92mm fan employs PWM to dynamically scale fan speed with compatible motherboards, but for the purposes of these tests the fan was run at its full speed of 2500RPM.

With an emphasis on copper, a very complex heatpipe pattern, and widely spaced cooling fins the Apack ZeroTherm BTF90 is a remarkably successful heatsink for socket AM2 or 939 AMD processors. Much more so than was ever expected to be frank.

At first glance any heatsink that takes the form of a butterfly, or apple, or whatever is bound to be of suspect usefulness. Yet, in spite of these first impressions the thermal test results for the Apack ZeroTherm BTF90 heatsink once again underscore that you can never tell how a heatsink will perform just by looking at it.
