A totally different type of fan than the ones we normally deal with. The Arctic S12038-4K is designed for high-performance servers, which is also reflected in its features. Very high airflow is provided by as much as 4000 rpm. And in order to ensure that the cooling performance does not drop significantly even through obstacles, the “extreme” Arctic fan has a profile that is as thick as 38 mm.
Airflow per euro
Explanatory note: The following charts will give a quick overview of the airflow rate per price unit. We can thus talk about the coefficient for the price/performance ratio. This is the ratio of the measured airflow rate in m3/h to the fan price (in euros) multiplied by 1000. This is specifically so that the results do not start with unflattering zeros.
Why is there a missing value sometimes? There may be more reasons. Usually it is because the fan could not be adjusted to the target noise level. Some have a higher minimum speed (or the speed is low, but the motor is too noisy) or it is a slower fan that will not reach the higher decibels. But the results in the graphs are also missing if the impeller is brushing against the nylon filter mesh. In that case, we evaluate this combination as incompatible. And zero in the graphs is naturally also in situations where we measure 0.00. This is a common occurrence at extremely low speeds with obstructions or within vibration measurements.
you should test the 8000rpm version. that is the holy grail – 3+3 push/pull on the AIO, 3 on the GPU, 2-3 case front, 1 case exhaust, 2-3 case base
And when the PWM fails, the pc just slams the door 😹
