Test System and Benchmarks

Test System and Benchmark Results of the Fractal Design S36 RGB

  • Ambient temperature monitored at case intake and temperature Delta was used.
  • All case and heat sink fans were benchmarked with fan control settings disabled and running at 100% unless otherwise specified.
  • Temperatures are averaged (last minute) from individual core temperature results monitored by AIDA64 after 15 minutes.
  • FPU load average is used to simulate worst-case scenario load levels similar to Intel Burn Test or OCCT, results marked “0″means thermal limit was reached and the CPU was throttled and thus the results were discarded.
  • Stock settings have all power saving features enabled in the motherboard power profile is set to “Balanced” in the OS. Multiplier at 51 at stock speed of 4.7GHz.
  • Overclocked settings have been adjusted, multiplier set at 54 to gain overclock at 5GHz.
  • All tests were taken at least three times to get the final result.
  • TDJ 834 was used for noise level measurement in dBA, 20CM away from the center fan exhaust.

Performance Summary:

Prior to any testing, I burn in the CPU cooler to get the best possible thermal benchmark numbers. What I experience playing around with Lumen S36 RGB is that the performance of the cooling was very much what I was expecting at the stock levels of Intel I7-10700KF. The idle temperature of 10700KF was 31C and under full CPU load temperature reached 52C. FPU Benchmarks showed me temperatures as high as 67C.

Looking at the system while being slightly overclocked (to 5GHz) I saw hotter temperatures. Under full CPU load temperature reached 60C and with full FPU load, I saw temperatures of as high as 82C. Thermal throttling of 10700KF starts at around 100C so I was getting worried but the temperature never reached higher than 82C.
