FrostyTech Mk.III Synthetic Thermal Heatsink Test Results Intel Core i7, Extreme Edition class heatsinks tested at a 200W heat load. Results based on readings from a 38x38mm copper interface die with 200W heat load on the Intel version of the Mk.III 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.

*heatsinks are ranked according to the 200w 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.

Frostytech's socket LGA2011 Intel synthetic thermal test platform stresses socket LGA2011/1366 compatible heatsinks with a 200W heat load. Keep in mind that the AMD Integrated Heat Spreader and Intel LGA2011 Integrated Heat Spreader both measure ~38x38mm, so these test results can be extrapolated to AMD processor scenario's as well.

With a 200W heat load applied by the Intel LGA2011/1366 version of FrostyTech's synthetic thermal test platform, the SilentiumPC Fera2 HE1224 yields result of 23.4°C over ambient at stock fan speed. Reducing the speed of the 120mm fan causes CPU die temperature to increase significantly, to 39.5°C over ambient.

Bottom line, the SilentiumPC Fera2 HE1224 is a good low noise tower heatsink at stock fan speed. It's not the coolest performing thermal solution in any of the three charts by a long stretch, but when noise output is taken into consideration, the Fera2 HE1224 heatsink offers competitive results and is worth considering.
