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

    Space Between Screw Holes Fan Size
    32mm 40mm
    40mm 50mm
    50mm 60mm
    60mm 70mm
    72mm 80mm
    83mm 92mm
    105mm 120mm
  • 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.

Can’t recommend highly enough!

When I required a replacement for my PC, I stumbled across Quiet PC who were mentioned in an article in an online magazine. I found their website rather pleasant. It offers a good selection of components with obvious focus on low noise levels, but without sacrificing performance, and doesn't overload the potential buyer with tons of options that are likely irrelevant. In other words, they focus on the components they know well. And that shows when you receive the PC (more in a moment). For my build, I had a few customisation requests and questions: I needed extra cables prepared for disks and a graphics card I wanted to fit in, because I didn't want to deal with cable management myself (If I had known how spacious the case is, I could have done it myself, though). Those requests were accommodated at no extra cost. Any questions I had were answered within a few hours, and during follow-up email conversation it rarely took more than an hour to receive a helpful response. Absolutely no copy&paste style emails from Quiet PC! Service and communication has been excellent throughout the ordering process (and beyond). When the PC arrived, I was positively suprised about the packaging as well as all the extra bits and pieces they ship with the computer: All manuals from individual components, all spare cables, lots and lots of screws for different purposes (put into nicely labelled bags), and even the remaining screws and brackets for the CPU cooler - including the CPU dust cover and extra thermal paste. In other words, you get all the original parts which weren't needed in the build, and then some! Before I first switched the PC on, I opened it to add all my disks and the graphics card. All the cables were prepared as I asked them to do. The cable management throughout was very neat and tidy. I have used other custom PC builders in the UK before, but none of them were even close to Quiet PC when it comes to cable management. So, do Quiet PC build quiet PCs? Absolutely, yes, and without any sacrifice on performance or temperature levels. The case fans and Noctua CPU cooler keep the i7-6700K and the system temperature in the low 30C range during idle and normal office work. I ended up replacing the case fans with Noctua fans, merely because I'm obsessed with noise levels and they are a bit quieter under load and can respond to raising temperature levels, but that doesn't take anything away from Quiet PC's choice -- The computer was already very quiet before, and the manual fan speed slider will be more than sufficient for the majority of users. (In fact you will hardly have to touch it; the idle airflow is good enough and you have to push the PC very hard to get temperatures beyond 55C for the CPU and low 40s for the system) I apologise for getting carried away with this review! :-) The bottom line is: brilliant service, including the option to have custom changes done; excellent build quality, packaging and spare parts; quick delivery (4 days in my case, instead of up to 7 as advertised). You can't go wrong with these guys!
