Scythe Ashura SCASR-1000 Heatsink Review
Scythe Ashura SCASR-1000 Heatsink Review
  75%   
Abstract: On the review bench today we have Scythe's Ashura heatsink; this is a fairly standard tower cooler equipped with a 140mm fan. The Ashura cooler stands 162mm tall, making it suitable for full tower cases where AIO liquid coolers are often too bulky.

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.

200W Thermal Test (°C) Noise Level (dBA)
*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 Scythe Ashura heatsink yields an average temperature result of 22.5°C over ambient at stock fan speed (1300RPM / 49.4dBA). Reducing fan speed to 800RPM drops noise output to a very quiet 37.5dBA but increases test temperatures to 26.6°C over ambient.

At full fan speed the Ashura heatsink performs quite well, without an excessive amount of noise output. Reducing the 140mm fan speed to 800RPM is perhaps a little lower than you'd want to go unless dealing with 85W TDP processors, but the thermal results aren't too bad in this operational mode either.

Bottom line, the Scythe Ashura is an overall very good heatsink for the Intel LGA115x/775 processor platform and a generally average heatsink on larger IHS bound Intel LGA2011 and AMD platforms. On processors with larger integrated heat spreaders, the slightly convex base of the Scythe Ashura acts as a bottleneck and restricts the amount of surface area conducting heat away from the CPU, with obvious results to thermal performance.
