Noctua NF-A8 PWM 12V 2200RPM 80mm Premium Quality Fan

These new 80mm fans have been updated to feature Noctua’s latest innovative technology. The NF-A8 PWM offers automatic fan speed control when connected to a PWM fan header on the motherboard.

Features

  1. Sound-optimised blade geometry and profile (Flow Acceleration Channels)
  2. Self-stabilising oil-pressure bearing (SSO2 Bearing)
  3. <14 dB(A) minimum noise with supplied L.N.A.
  4. 32.6 CFM maximum airflow
  5. Includes 4 Vibration-Compensators
  6. Six years warranty

The NF-A8 is a highly optimised, premium quality quiet 80mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 further improves the renowned quiet cooling performance of the award-winning NF-R8. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 2200 to 1750rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.

Customer Reviews

Outstanding performance

,

Bought to quieten a 2U rack mounted PC. Excellent performance as ever from Noctua with a great range of mounting options (screws and rubber retainers), Y-splitter, cable extender and low noise adaptor.

Well worth the investment.

Great manufacturer

,

Not my first Noctua fan, and I doubt it’ll be the last. When I first replaced my case fans with Noctua PWM units they were so quiet I wasn’t sure they had powered up until I looked - that’s how much of a difference they made to the previous fans.

Excellent product and reliable.

,

I purchased this fan to replace my near 10 year old CPU fan on my “old HP Pavilion” together with a new system fan, after the upgrade my PC was almost whisper quiet, near quiet as a laptop, after checking the system using CPUID HWMonitor it proved to be adequately cooling the CPU and working reliably providing active cooling when needed, and a thank you to Simon Elliot for technical assistance and easing a worried mind concerning temperatures.

A complete Must of course!

,

My Acer Aspire X3810 MiniDesktop is very heat producing; no other solution can solve this issue, after this Noctua NF-A8 fan to heatsink replacement! Now, this PC unit is one of the best of its own. Smart fan option must be disabled from BIOS and supplied extension cable(min.1750rpm)must be used. Very silent and thermal efficient!

FAQ

  • How do I measure fan size?

    The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. This isn’t really dictated by customer preference, but more by recent designs of PC cases.

    As for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. All our fans are 25mm thick unless otherwise stated. If you have any questions about which fan you should order, please don’t hesitate to get in touch.

    If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally.

    Screw hole spacings and fan sizes

    32mm between screw holes:40mm fan size
    40mm between screw holes:50mm fan size
    50mm between screw holes:60mm fan size
    60mm between screw holes:70mm fan size
    72mm between screw holes:80mm fan size
    83mm between screw holes:92mm fan size
    105mm between screw holes:120mm fan size


  • I received a small cable (resistor) with my fan; what is it for?

    The resistor cable (also called Ultra Low Noise or ULN cable) is designed to allow the fan to run slightly slower for even quieter operation. The benefit in lower running noise is significant. Although the airflow will be reduced slightly, this usually has minimal effect on PC temperature. We would generally recommend using the ULN resistor cable for best results in almost all circumstances.

  • How can I tell which way the air blows through the fan?

    Hold the fan so that the round fan sticker is facing you. You are looking at the rear of the fan. When you plug the fan in, the air will be blowing towards you. If you want a fan to act as an air intake, then the fan sticker will be facing the inside of the case. Some fans also have two small arrows moulded into their plastic housing - one arrow shows the direction of airflow, and the other (at 90°) shows the direction of blade rotation.

  • Is it possible to use a 4-pin PWM fan or CPU cooler with a motherboard which has only 3-pin fan headers on it?

    Electrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows.

    The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.

    Another avenue to explore is the possibility of using a bay-mounted fan controller. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.
