I left the whole setup on the Streacom BC1 benchtable without fans that would provide airflow. The stress tests were performed as usual using the Aida64 Extreme application with a duration of 45–60 minutes. For obvious reasons, I only tested the cooler on the base clock of the processor without overclocking. At the same time, however, I expanded the range of tests by more speed levels. So I first tested the Noctua NH-P1 cooler in passive mode, followed by two sets with the added NF-A12x25 LS-PWM fan at four speed levels (300, 600, 900 and 1,200). In the first set, the fan was placed on top of the cooler and the air flow was directed upwards. In the second set, I then placed the fan on the side of the cooler so that air could flow from the PCI Express slot through the fins toward the top edge of the motherboard. The CPU power consumption during these tests was 85–90 watts, a similar value to current mid-range processors.

"Anyway, Noctua NH-P1 is a very interesting piece of hardware. Even in the fully passive mode, it manages to efficiently dissipate waste heat corresponding to today’s mid-range processors. The addition of the new NF-A12x25 LS-PWM fan will even further increase its efficiency without dramatically increasing the noise." (Pavel Sekerka, HWCooling.net)
