Alpenfohn Matterhorn Pure 35 °C 59 °C
Cooler Master Hyper 103 36 °C 60 °C
Thermolab Bada 2010 39 °C 64 °C
Scythe IORI Scior-1000 42 °C 66 °C
Thermolab LP53 39 °C 67 °C
Thermolab ITX30 39 °C 70 °C
Intel Stock 39 °C 75 °C


At this point we plugged the fan(s) to the motherboard CPU fan header and let the motherboard take care of fan speeds. In other words the motherboard will adjust the fan speed via PWM signal according to CPU temperature. The idle temperature is the lowest temperature hit by the processor package after 10 minutes idle. The load temperature is the highest temperature hit by the processor package after one pass of wPrime v2.10. The wPrime test takes 4 minutes puts load on all 8 threads. Room temperature is 25°C.

Fan Speeds

  Idle Load
Scythe Ashura 436 rpm 550 rpm
Noctua NH-U12S Dual Fan 380 rpm 687 rpm
Noctua NH-U12S Single Fan 450 rpm 740 rpm
Alpenfohn Matterhorn Pure 471 rpm 770 rpm
Scythe IORI Scior-1000 424  rpm 880 rpm
Corsair H75 Single Fan 800 rpm 969 rpm
Enermax Liqtech 120X 580 rpm 970 rpm
Enermax ETS-T40 Black Twister 820 rpm 1'110 rpm
Raijintek Themis EVO 990 rpm 1'115 rpm
Prolimatech Lynx 765 rpm 1'077 rpm
Enermax ETS-T40 While Cluster 920 rpm 1'170 rpm
Raijintek Pallas 952 rpm 1'170 rpm
Raijintek Nemesis Dual Fan 1'120 rpm 1'190 rpm
Raijintek Nemesis Single Fan 1'120 rpm 1'270 rpm
Cooler Master Hyper 103 950 rpm 1'465 rpm
Thermolab Bada 2010 1'250 rpm 1'500 rpm
Intel Stock 1'230 rpm 1'630 rpm
Thermolab LP53 1'475 rpm 1'672 rpm
Thermolab ITX30 1'475 rpm 2'253 rpm


Values are in RPM, we took the lowest speed hit by the fan(s) in idle and the highest under load.

Noise Levels

  Idle Load
Noctua NH-U12S Single Fan 32.0 dBA 32.0 dBA
Noctua NH-U12S Dual Fan 32.0 dBA 32.4 dBA
Alpenfohn Matterhorn Pure 32.0 dBA 32.7 dBA
Enermax Liqtech 120X 32.1 dBA 32.8 dBA
Enermax ETS-T40 Black Twister 32.3 dBA 33.0 dBA
Corsair H75 Single Fan 32.2 dBA 33.2 dBA
Enermax ETS-T40 While Cluster 33.0 dBA 33.2 dBA
Scythe Ashura 32.0 dBA 33.4 dBA
Cooler Master Hyper 103 32.0 dBA 33.6 dBA
Prolimatech Lynx 33.3 dBA 33.9 dBA
Raijintek Nemesis Single Fan 33.5 dBA 34.2 dBA
Thermolab Bada 2010 33.8 dBA 34.2 dBA
Intel Stock 33.3 dBA 34.4 dBA
Scythe IORI Scior-1000 33.2 dBA 34.6 dBA
Raijintek Nemesis Dual Fan 33.7 dBA 34.6 dBA
Raijintek Themis EVO 34.8 dBA 35.3 dBA
Thermolab LP53 34.0 dBA 36.8 dBA
Thermolab ITX30 34.1 dBA 37.6 dBA
Raijintek Pallas 35.9 dBA 41.4 dBA


Decibel meter (Voltcraft SL-200) has been placed 1 meter away from the cooler. Measurements are conducted in a quiet room, where there are no other noise source. 32 dBA is the lowest we can get in our room. Also here the measurements are conducted at lowest and highest fan speeds in idle and under load respectively.
