Since all Thermalright coolers were tested with one or two identical Scythe Slip Stream 120 fans, the acoustic measurements actually turned into measuring the level of noise generated by the fan(s). And since ZEROtherm Nirvana Nv120 Premium cooler features its own fan, its results were taken separately. We measured the level of noise generated by our today’s testing participants from a 3cm, 1m and 3m distance. The results are given on the diagram below:
As you can see, the coolers can be actually used only with slowly rotating fans, like a couple of SlipStream 120 at ~860RPM or ZEROtherm Nirvana NV120 Premium fan at ~1280RPM that yielded just a tiny bit to the competitors. All other combinations may only be used for short-term benching, as they prove excessively noisy.
