Frequency Plots
10% Fan Speed
A notable noise spike here at 2 KHz.
25% Fan Speed
At 25% true speed or 758 RPM, I found a low bearing noise generated mainly from a noise spike at 160 Hz, besides the increased noise in the 1.6 – 2 KHz region.

100% Fan Speed
The noisiest frequency at full speed is the 500 Hz one.

Is there a wiring diagram available for the Alphacool Apex Stealth 2000 fan? We are using in a non-computer application & need to know which wire/pin is ground.
usually the black pin is ground
The Phanteks T130-120 might not leave room for competition, but it’s the only one 30 mm high, instead of 25 as all the others.
Looks a tiny bit unfair this way, if you ask me.
Very good review. Love the page 8 normalized noise tests.
– Woud love a ”real world” thermal test like der8auer did with a radiator too. Lot of numbers, cfm, noise etc but what does it translate in °C ?
– Wish you added to the charts : Noctua NF-A12x25 PWM /// be quiet SILENT WINGS PRO 4 120mm PWM /// ARCTIC P12 Max
And when you hit the max speed for exemple noctua remove it for the later stages.
I usually set my fans 800-1000 RPM idle and 1300-1800 for gaming.
We will add more soon. We are re-testing most stuff right now.
A real-world test would only cover 1% of all possible scenarios because some radiators need high airflow, others high static, and others a mix.
In the real world, you see static in cooling systems and airflow for chassis use.
