To test the AURAFLOWx 240’s cooling abilities we will be running it through 2 different testing scenarios. The first is a true torture test with a well-known program called “Prime95”. This really pushes the 8700K to its limits and produce a massive amount of heat that then has to be dissipated by the AURAFLOW. The second test will simulate more of a real-world workload by using the benchmark “Cinebench R15” and running it 5 consecutive times. We have found that this test should produce temperatures that you would see your system produce when doing heavy workloads.
To start our testing, we ran our 8700K at stock speeds which have a clock of 4.3GHz when running AVX workloads. Once we configured our 8700K at stock speeds, we let the system idle for 5 minutes and recorded the lowest temperature and then proceed running Prime95 for 20 minutes. Once our run of Prime95 had concluded, we record both the maximum and average temperature and the CPU Package. We then proceed to our Cinebench test by running the CPU benchmark 5 times in a row and then also recording the CPU Package temperatures.
With stock settings, we see our idle temperature level out at 29c and after our Prime95 run we top out at 75c with an average temperature of 62c. In Cinebench, the AURAFLOW manages to keep the 8700k at a cool 63c with an average temperature of 60c.
Prime95 – 4.3GHz @ Stock Voltage
Cinebench – 4.3GHz @ Stock Voltage
These temperatures are well below our self-imposed max temperature of 90c so we proceeded to clock our 8700K to the 4.6GHz profile. With the increase clock speed and voltage, we see the idle temperature rise a few degrees which settled at 31c. We saw similar increases in our Prime95 test with the max temperature increasing 4c to a 79c and our average temperature now hitting 64c. Cinebench also saw a slight increase in temperature with the max now sitting at 67c and the average 61c.
Prime95 – 4.6GHz @ 1.3v
Cinebench – 4.6GHz @ 1.3v
We still have plenty of headroom so we proceed to overclock the 8700k to its final stable profile of 4.8GHz with a voltage of 1.355. We have attempted in the past for a higher clock rate but the 8700K just can’t maintain a stable OC with any amount of voltage we throw at it. In our final run, we see our idle temperature have a modest increase of 1c with it sitting at 32c. In Prime95, we do see that additional voltage at work with a max temperature increase of 9c topping out at 88c with the average only increasing 4c to 68c. This is mirrored in the Cinebench test with the max temperature now sitting 8c higher at 75c with an average temperature of 68c.
Prime95 – 4.8GHz @ 1.355v
Cinebench – 4.8GHz @ 1.355v
The AURAFLOWx 240 did an amazing job at keeping the 8700k temperature down and with it, we managed to hit our max clock of 4.8GHz while maintaining a temperature below 90c in Prime95.
