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.

*heatsinks are ranked according to
the 150w 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. |
intel processors vary widely in heat output between
single and multi-core processors, so we rely on two values which represent the
upper limit of both existing cpu families to test thermal solutions.
With a 150W heat load applied
by the Intel LGA775 version of FrostyTech's synthetic
thermal test platform, the
Enzotech Ultra-X heatsink yields an excellent rise above ambient temperature of
only 20°C,
with 59.1dBA noise. That thermal test result immediately puts
the Ultra-X heatsink in the top 10, with the likes of Thermalright's Ultra-120 and Zalman's CNPS9700-LED.
When fan speed is dropped down to 1200RPM, the
temperature on the 150W test die rises to 30.0°C over ambient. Noise levels fall to
a fairly quiet 40.1 dBA.
The Enzotech Ultra-X heatsink was also tested with an 85W heat load. In this situation at stock fan speeds, the
heatsink maintains a fantastically low 8.5°C result over ambient temperature! When the fan is again
dialed down to 1200RPM, the Ultra-X heatsink reacts in a predictable manner but CPU die temperature rises only to 15.5°C
over ambient.
In both
these cases, the Enzotech Ultra-X heatsink maintains the lowest temperature
of any Intel LGA775 heatsink FrostyTech has tested on the 85W synthetic thermal test platform
to date! When tested with a 150W heat load, the Ultra-X is firmly in the Top 10 heatsinks of both AMD and Intel classes. Enzotech and their large parent company have certainly produced a really winner
here, the Ultra-X heatsink is one of the coolest running Intel and AMD compatible thermal solutions out
there. Recommended.
