Product information

Noctua NF-A6x15: a 60 mm fan for more air at low speed

The Noctua NF-A6x15 measures 60 × 60 × 15 mm, making it a 60 mm fan that still fits where things are tight. It runs at 5 V and is PWM controlled through a 4-pin cable – control stays with your miner and its fan curve.

Rated figures are 19.8 dB at 0.85 W. The fan is audible but even, and it changes nothing meaningful about running costs: at €0.28/kWh it is under 20 cents a month in continuous operation.

Why a 60 mm fan at all?

  • More air per revolution: the larger area of a 60 mm fan achieves more throughput at low speed than a small 40 mm one. Quiet here comes from speed, not from doing without.
  • Slim build: at 15 mm deep it fits builds where a thick 60 mm fan would collide.
  • Familiar connection: 4-pin PWM at 5 V, so no external controller and no separate power supply.
  • Honest classification: 19.8 dB is not silent. Customers mainly praise the calmer running noise – at maximum speed you hear this one too.

Where the NF-A6x15 belongs

Anywhere a 60 mm frame is provided. The NerdQaxe Copper Pro is designed for a 60 mm fan from the factory, and the NerdQaxe Performance Case takes two 60 mm fans at the rear for active back-panel cooling.

It does not fit boards with a 40 mm fan mount such as the Bitaxe Gamma or Nerdaxe Gamma – the NF-A4x20 belongs there. It also does not fill the 92 mm mount of a NerdQaxe++; there it only makes sense inside the Performance Case as additional rear cooling.

Who the NF-A6x15 is for

For setups with a 60 mm mount in continuous operation: if you actively ventilate the rear of your NerdQaxe or swap an existing 60 mm fan for a calmer one, you gain temperature headroom without raising the noise floor.

It is less suitable in two cases: on a board with a 40 mm fan mount it simply does not fit, and if you expect absolute silence, keep the 19.8 dB in mind – at full speed a fan remains a fan.

What you need to fit it

A free 60 mm fan mount, a 5 V connector with PWM and a screwdriver. If you want to run two fans in the Performance Case, work out beforehand how both get power. After fitting, check ASIC temperature and fan speed, just as when setting up the NerdQaxe.

Accessories and sensible upgrades

Ready for a quieter NerdQaxe setup?

The NF-A6x15 is the right choice when your build offers a 60 mm mount and you want to keep temperature and noise under control at the same time. It does not replace cooling surface, but it makes sure the surface you have gets air even at low speed.

Frequently asked questions about the Noctua NF-A6x15 Silent Fan

How loud is the Noctua NF-A6x15?
The rating is 19.8 dB. That is noticeable in a quiet room but even and without disturbing bearing noise. At full speed you hear it clearly – in everyday use the fan curve usually keeps it far below that.
Does the NF-A6x15 fit a Bitaxe Gamma?
No. The Bitaxe Gamma has a 40 mm fan mount, so a 60 mm fan is too large. The Noctua NF-A4x20 is the right size for that board.
Does the fan fit the NerdQaxe Performance Case?
Yes. The rear of the NerdQaxe Performance Case is prepared for two 60 mm fans, which is exactly this size. The fans are not included with the case, so you order them separately.
What is the difference between the NF-A6x15 and the NF-A4x20?
The NF-A4x20 is a 40 × 40 × 20 mm fan at 14.9 dB and 0.5 W for the stock mounts on Bitaxe and Nerdaxe boards. The NF-A6x15 measures 60 × 60 × 15 mm at 19.8 dB and 0.85 W and moves more air at the same speed.
How much electricity does the fan use?
0.85 W at 5 V. In continuous operation that is less than 20 cents a month at €0.28/kWh.
Exactly how slim is the fan?
15 mm deep with a 60 mm frame. That is exactly what it is for: 60 mm of area in places where a thicker fan no longer fits.
Do I need a separate fan controller?
No. The fan has a 4-pin PWM cable and runs at 5 V, so it works with your miner’s existing control.
Can I run two fans at once?
Yes, the Performance Case is designed for exactly that. Work out how both fans are supplied before fitting – with only one free header you need a splitter.
Does the fan fit directly onto the NerdQaxe++?
Not on the main mount: the NerdQaxe++ comes with a 92 mm fan. A 60 mm fan only becomes useful there inside the Performance Case, which offers two additional positions at the rear.
Does the fan bring more hash rate?
Not directly. It lowers the temperature, and a cooler ASIC runs more stably – especially if you adjust frequency and voltage.
Does the fan replace a larger heatsink?
No. A fan carries away heat that the heatsink has to absorb first. If temperatures are permanently too high, more cooling surface is the first step and the fan the second.

Läuft zuverlässig

Ich habe lange verglichen und mich am Ende hierfür entschieden. Die Verarbeitung entspricht der Qualität, die ich von Noctua erwartet habe. Die Temperaturen bleiben trotz der ruhigeren Akustik stabil. Der Kauf hat sich für mich gelohnt.

Gutes Produkt

Bestellung und Inbetriebnahme haben problemlos funktioniert. Die Verarbeitung entspricht der Qualität, die ich von Noctua erwartet habe. Das Kabel könnte für meinen Aufbau etwas länger sein. Insgesamt bin ich trotzdem sehr zufrieden.

Sauber verarbeitet

Der Lüfter läuft deutlich angenehmer als das vorherige Modell. Vor allem das gleichmäßigere Laufgeräusch ist angenehm. Ein rundes Gesamtpaket.

Schnell eingerichtet

Ich nutze Noctua NF-A6x15 inzwischen seit einigen Wochen. Die Verarbeitung entspricht der Qualität, die ich von Noctua erwartet habe. Der Unterschied zu meinem vorherigen Setup ist klar spürbar. Die Temperaturen bleiben trotz der ruhigeren Akustik stabil. Qualität und Funktion stimmen.

Gute Qualität

Für ein leiseres Setup war der Austausch bei mir genau richtig. Bisher gibt es nichts zu beanstanden.
