- Noctua NH-U9S chromax.black
- Thermaltake TOUGHLIQUID Ultra 360
All tests were run in our custom-built computer to best reflect real life performance. The computer remained in the same location in the same room throughout all tests. The room temperature in our testing lab was around 22c. Stock thermal paste respective to all coolers were used to rate its performance; all thermal pastes were given a proper amount of time for them to fully settle. The fans on all heatsinks were connected to the motherboard's CPU 4-pin fan header. The test computer was turned on and left idling for at least one hour for the idling tests. High CPU load results were obtained using the Prime95 in-place large FFTs test with a maximum number of worker threads for the tested CPU for a minimum of 10 minutes or until the temperature was deemed stable. Temperature results were measured with HWiNFO, which reports the CPU's integrated digital thermal sensor for maximum accuracy. Each temperature result was calculated by taking the maximum value of the cores inside the CPU.
After letting my computer sit idle for a while, I shook my mouse to wake the computer to check the temperature. From the first graph, you can see the be quiet! Pure Loop 2 FX 240mm idled at the lowest temperature of 23c. This is among the coolest idle temperature readings across all of the tested coolers, matching the larger Thermaltake TOUGHLIQUID Ultra 360 and the Noctua NH-U12A chromax.black, which is great to see. This being said, idle results do not give a full representation of what CPU coolers can do, so we started up the Prime95 tests to see the more pertinent results.
With more than enough time to load the processor, you can see how all of the coolers performed with the peak temperatures recorded. From here, you can see the strong result of the be quiet! Pure Loop 2 FX, with a full load temperature of 73c. This is three degrees warmer than the TOUGHLIQUID Ultra 360, and one degree warmer than the NH-U12A, but this is still a pretty impressive result. This also matched the Noctua NH-D12L. This cooler was clearly more than capable of ensuring enough headroom so that the CPU can maintain the same maximum frequencies as other coolers.
As for the sound analysis section, on a scale of 0 to 10 where 0 is silence and 10 is very loud, I would rate the be quiet! Pure Loop 2 FX at around 4.0/10 under full load. The two Light Wings fans and water pump was reasonably quiet despite running full bore in our tests. On a day-to-day use, the cooling solution is notably quieter than the original Pure Loop, which is another bonus, and is similar in noise output compared to some air coolers. I also appreciate the addressable RGB lighting on the fan, which provides some nice colors to my system.
