CPU Case Fan Sizes (How do you determine fan size)

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


How To Determine cm VS mm Calculation:
You can Easily measure your Fan's size with "Measuring Tape". But problem is there is only Inch and Centimeter scale. SO how can you really calculate your fan size with your measuring tape. Here is the process. 1st measure your fan size with cm. Then keep in mind that 1 cm = 10 mm. Thats it, now you can measure your fan size by your own.


If you have more questions pls let me know. Thank you.
