Dual fan configurations are very popular amongst the All-in-One liquid CPU cooling audience. Various units are supplied with a pair of fans, and many of those that aren’t quickly get upgraded by their users.
We wanted to test if a pair of lower RPM fans is able to offer improved cooling performance with a reduced noise output.
The fans of choice were Noctua’s NF-F12 PWM models. They operate at a maximum speed of 1500 RPM with a static pressure of 2.61 mmH2O and airflow rate of 55.5 CFM. As with our previous testing, both fans were set to 100% speed and rear intake.
Cooler Master’s decision to use the 2400 RPM Blade Master was a very good one, as proven by the fact that it is able to match the cooling performance of a pair of Noctua’s premier 120mm models.
A sizeable decrease in the Seidon 120M’s maximum noise output can be achieved by using a pair of high quality, lower RPM fans.
