Customer Reviews



Bought this for PSU unit. At first glance I did notice a slight noise reduction but then realised that the noise is generated by the turbulence that this fan air flow is making. Did some adjustments and I have to admit that this 1700 rpm fan is really quiet!

Great pwm fan


Very good airflow, low noise. I use two of them with Megahalems and combo is great.

Very poor airflow for the size


First off, just as we know all 90mm fans are often in fact 92mm and we find that most 120mm fans are actually 119mm, so Coolink seem to have played things by the book and gone for 120mm or maybe eve a shade more. Which means its going to be a tight fit and might need some sanding down for some uses/cases.

Secondly, we all know quiet fans seldom shift as much air as the noisier ones. That’s the deal, the trade off. Some fans, such as in my experience the Noctua and Fractal Design ones on this site, really do impress on being well on the clever and effective side of that equation. However, sadly this grey and green monster promises much but delivers only a feeble gentle breeze. Yes its very quiet, but then so is my teddy bear or a pint of milk. I’m thinking of putting an old Panaflo fan back in ... and at least it will fit too! For a fan this size air throughput is disappointing even if it is quiet. Wrong side of that trade off equation. Look elsewhere would be my advice

Lots of air at slow speeds


This, and the coolink range, really push and pull air through well at slow and more importantly quiet speeds.

I use a pair of these either side of a water cool rad both pulling in cool air. I then have two of the 80mm Coolink fans drawing hot air out.

The rubber grommet type anti vibration alternatives to screws are great but only usable if you can get your hands or small pliers in the case to pull them through the screw holes.

Very distinctive colour and fan blades leads and connectors are all great quality for the price. Y lead splitters are also included... very handy for running two fans off one connection.

Excellent Product


I bought one of these to replace the stock fan on a Titan Fenrir CPU cooler, I am getting 3 degrees lower temps overall!


  • 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.

“Excellent Service, Products and Support - Highly Recommended”

“I was looking to purchase a stable and reliable high end Business Computer, so it was vital that I chose a company I could trust for their advice, products and support.

I researched the main UK suppliers and brands, and some were competitive on pricing. However, after contacting these retailers and reading customer reviews on various websites (including TrustPilot) about them, they seemed to fall short on the “trust” issue when it came to their service, products and/or support.

The exception to this was Quiet PC, and some of the reasons for this are listed below:

- Over numerous phone calls, Andy spent a lot of time going through all of the Hardware and Software options to advise me on the best Computer System for my requirements. All phone calls were returned, questions answered, and emails responded to quickly (basically, they do what they say they will do).

- The website is excellent. You can go through every Hardware and Software option for the System you are interested in and configure exactly what you want for your budget. The System configuration can be saved for later, or purchased via the simple Checkout process. Order Confirmation and Despatch emails are sent thereafter.

- My system was ordered on the Tuesday afternoon, and built, tested, despatched and delivered by Friday (Using my chosen carrier UPS).

- The Computer System was packaged in the noFan computer case box, and all manuals - discs - cables were packaged in the motherboard box. Then, these two boxes were packaged with one very big box (with plenty of packing material), so they arrived in perfect condition. Everything I ordered was present and accurate (Hardware Components and Software).

- I have been using the Computer for a month now, and it works perfectly. The noFan case is totally silent, produces hardly any heat, and I would imagine uses far less power than an active fan based system. No free trial (junkware) software installed, and the system comes with a two year guarantee.

- I have received after an sales support email from Ellen to see if everything is ok, but I have not had to contact them with all being fine so far.

The TrustPilot reviews were very valuable to me in making my decision on who to purchase from, so hopefully my review will be helpful to others also.
