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.

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.

So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything.

Screw hole spacings and fan sizes 32mm between screw holes:Įlectrically, 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. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally. 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. If you have any questions about which fan you should order, please don’t hesitate to get in touch. All our fans are 25mm thick unless otherwise stated. This isn’t really dictated by customer preference, but more by recent designs of PC cases.Īs 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. 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. The size of fan you need will generally be determined by the size of the fan fitting position in your PC case.
