Testing Results, Low Fan Speed
Using a PWM voltage regulator, we reduced the speed of the fans manually down to half their rated speed, which is 900 RPM. The pump was also connected on the same power source, functioning properly at this low speed setting.
| Core Temperature, Constant Thermal Load (Low Fan Speed) |
The Helor 240 does very well in this test, with an average thermal resistance of 0.0997 °C/W, a fine figure for a 240 mm AIO liquid cooler. It produces 35.2 dB(A) of noise under these working conditions, making it practically inaudible when installed inside a typical PC case. It does not outpace all of the equally sized AIO coolers that we have tested but those that do perform better also are noticeably louder.
The larger size of the Helor 360 does improve its thermal performance, but the inclusion of a third fan does increase the noise level of the device, even if only slightly. It has an average thermal resistance is 0.0867 °C/W, one of the best performance figures that we have ever recorded. Nevertheless, it is being outpaced by its primary competitor, even if only slightly.

Why dont you throw in a few high end air coolers like thermalright, noctua, be quiet!?E.Fyll - Monday, December 9, 2019 - link
You can easily check their performance figures in several of our air cooler reviews. The average thermal resistance figures are directly comparable, the test setup is exactly the same.Pro-competition - Tuesday, December 10, 2019 - link
Great! What TIM do you use? Do you standardise the thermal paste used (e.g. only use Thermal Grizzly Kryonaut) or the TIM that comes with the cooler?JanW1 - Tuesday, December 10, 2019 - link
Very conveniently for the Cougar Helor, many of the tested coolers were not included in the Thermal Resistance vs Sound Pressure chart, as it would be much more obvious that this cooler is rather middling in performance.Among the selection tested here, the Alphacool NexXxos completely dominates the competition in cooling performance per noise but that reference point was omitted. Why? It wouldn't crowd the graph since it's apart from all others. Maybe not the same market, but the cooler was part of this test and would have been an informative reference.

Yeah, that Alphacool NexXxos looks like da real MVP.nathanddrews - Tuesday, December 10, 2019 - link
Ah, it's also double the price and a self-assembled open loop system.bwanaaa - Tuesday, December 10, 2019 - link
i guess the kraken x62 is slightly better if not only its performance but the ability to mount on ryzen/TR.Foeketijn - Tuesday, December 10, 2019 - link
We've seen with swiftech and Alphacool, the most important part is a copper radiator. But yeah copper costs a couple of cents more, So yeah, lets just add RGB and hope the blinking light distract the potential buyer from the cheap design choices.nathanddrews - Tuesday, December 10, 2019 - link
I read your comment because it had RGB in it.Foeketijn - Wednesday, December 11, 2019 - link
nice one
