We used the default PWM setting for the testing.
Sound Level Testing
We used a standard generic digital sound level meter at 15 inches. It is important to note we used the MicroCool Banchetto 101 Chassis for testing which is an open chassis. This means you are hearing the CPU coolers fan unobstructed.
We use Arctic MX-2 for all heatsink cooler tests and in fact we use it for all builds, test or otherwise. We run the AIDA64 Engineer stability test as our burn in programme for thermal paste, which allows the paste to spread out and share the love across the mating surfaces. It is worth doing, we always notice a drop in temperatures after 30 minutes of burn in.
Ok, on with the testing. AIDA64’s CPUID showing 3.3Ghz stock and 3.6Ghz Turbo clocks.We used the i7-5820K and some Corsair Vengeance LPX DDR4 2666Mhz.
Stock temperature results are excellent, beating our personal favourite, the NH-D15 into second place, the first air cooler to do so.
Sound level results at stock settings are a little different, with the Noctua NH-D15 showing its muscle with only 0.1 Db’s louder under load conditions than the R1 at idle.
It’s also louder than the be quiet! Dark Rock Pro 3 at idle, but firmly beats it under full load stock stress test conditions.
