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.
AIDA64’s CPUID showing 3.3Ghz stock and 3.6Ghz Turbo clocks.We used the i7-5820K and some Corsair Vengeance LPX DDR4 2666Mhz. This is our standardised enthusiasts test rig, with all tests controlled using the same conditions to ensure compatible results.
The Cryorig H5 Ultimate hits the top of the results chart at idle, though only by one degree over its big brother, the Cryorig R1 Ultimate. Excellent results and should provide some efficient cooling at idle, important for the life of your CPU.
Under load conditions, the H5 Ultimate is slightly warmer than the Cryorig R1 Ultimate and beating our favourite cooler, the Noctua NH-D15. It’s impressive stuff for a single fan cooler, but this isn’t where the designs will show their strengths, but it’s a very good start.
