Ultra-Quiet 92mm fans

92mm fans are most often used as case fans to provide extra airflow through the computer case. They are not as common as 80mm fans, or more recently 120mm fans, but nonetheless we are pleased to offer a wide choice of top quality fans which will provide quiet and safe cooling for many years to come. If your PC case accommodates a 92mm fan or two, any of our range of 92mm fans will not let you down.

To convert airflow in cubic feet per minute (CFM) to cubic metres per hour (m³/h), multiply the CFM figure by 1.7.

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.

“What’s not to like ...”

“I was a little nervous about web-buying a high-end computer from outside the US from a company I’d never heard of … my credit card company was even more so. I was looking for an Ubuntu-preloaded machine. I liked the “quiet computer” concept, the sentinel model came well-equipped, with a nice small-form factor, some configuration flexibility, and a sensible price. While I hesitated, the fully-fanless model went out of stock, oh well, so I went for the not-quite-fanless “breeze” model.

It shipped 4 calendar days after I ordered and I received it 5 calendar days later. International and during the holidays, I’m not sure how they turned this around so quickly. Follow-through and follow-up were prompt, attentive, friendly, personal, and hassle-free. I like doing business with companies that I enjoy doing business with, and those seem to get harder and harder to find.

The computer has just arrived, so it has not yet been run much. There were no surprises. Everything on the order appears to have been in the box. I plugged it in and it booted. Since I bought a solid-state boot drive, it booted really quickly. Ubuntu was there and ready to use.

There is an external power-supply, which I had not given thought to until it arrived. And, I did find it curious that the bits leftover from assembling the computer, the things I might have kept if I’d assembled it myself, were included in the box. Unexpected. I may be glad I have them, later.

When I was a small child, my dad drove a little British sports car, which he enjoyed running as much as I hope to enjoy running my little British computer.”
