Test System and Benchmarks

  • Temperatures are averaged (last minute) from individual core temperature results monitored by the AIDA64 System Stability Test after 30 minutes of the run time.
  • 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 with Vcore set automatic and Multiplier at Auto at a stock speed of 4.9GHz with Enhanced Multicore options enabled.
  • Overclocked settings have Vcore voltage set to 1.428V with the adjusted multiplier set at 51 to gain overclock at 5.1GHz.
  • All tests were taken at least three times to get the final result.
  • VLike VL6708 Digital Sound Level meter was used for noise level measurement in dBA, 20CM away from the center fan exhaust.

The iCUE software was set for each test. One test was done with the fans and the pump set to balanced and the other test was set to extreme. This was replicated for the overclocking tests as well.

First, we’ll look at the iCUE H115i results when the Intel Core i7-9700KF is in the stock configuration.


Balanced Results

With the balanced profile selected in the iCUE software, you can see the observed load temperature is around 65°C and we see a 42.8°C delta temperature. The FPU only test hit 80.2°C with a 58.2°C delta. Overall I was pleased with the balanced profile results. As far as sound, the balanced profile measured 44.3 dBA on my meter and could barely be heard. According to the iCUE software the fans were spinning at 300 RPM and the pump sat at 2318 RPM.

The extreme profile for both the pump and fans yielded lower temperatures but with a bit more fan noise. The observed load temperature measured at 60.3°C with a 38.3°C delta and the FPU only test came in at 75.1°C with a delta of 53.1°C. The fans spun up to 1100 RPM and the pump to 2614. The noise level measured 50.8 dBA


Next, we move on to overclocking. I was able to set the multiplier to 51 in the BIOS and get the CPU stable at 1.428 volts. I ran the same tests with the balanced and extreme set for both the pump and fans.

With a minor overclock to 5.1 GHz, temperatures are still acceptable. The observed load temperature rose to 74.7°C with a delta of 52.7°. The FPU jumped a bit to 81.5° observed with a 59.5° Delta.

Pushing the extreme profile in iCUE yields a pretty good drop in temperatures. The iCUE H115i was able to keep temperatures in check with a 70.5°C observed load temperature with a 48.5°C delta and with FPU only a 76.6°C temperature was observed and a 54.6° delta temperature was obtained.  According to the iCUE software, the fans were running at 1260 RPM and the pump at 2643 RPM with a measured noise level of 50.6 dBA.

  1. Have been looking to replacing my now “noisy pump” 360 AIO. Per Tom’s review a Corsair H150i RGB Pro XT, 360mm Radiator, Triple 120mm PWM Fans will cost me $181 at Amazon. Moreover the fans are not RGB LED and are quite plain. Then having to purchase extra or missing RGB fans will run me an additional $45 each. I love the Corsair brand…but for their new with RGB fitted AIO costing upwards to $300 is hard to swallow and for many a clear $$$ deal-breaker. It also makes me think that the entire (industry) AIO marketing is going bonkers and needs to return to reality for the man on the street!
