Especially once it replaced the old 80 and 92mm, fan models, for cooling the most PC case as a standard fan size. The 120mm diameter is the standard case fan size. They currently have little use in the market compared to other computer case fan sizes. In the chassis, they have hardly been used as such, except in specific models.

However, models with this diameter are often used a lot in the heatsinks of some graphics cards. But with less RPM due to its size.ĭespite the fact that that they work at lower rpm, it is still evident that, except for the models of certain brands, they are still louder than average. When larger fans were required, 92mm variants of these same models were released as an improvement on previous 80mm models. Currently, such cooling fans are being used for small PC cases like small Mini ITX, Mini STX, or Mini ATX cases, as well as SSF, HTPC. Follow this guide PC fan types to find out which one you need for correct cooling and extending the life of the components of your personal computer.Īnd for being remarkably loud. In this post, I will help you to know ‘ what are sizes of fans are there for PC towers‘. The fans are one of the key pieces that’s why there is a huge variety of computer case fan sizes available in the market including various standards. It is worth and very important to control the temperature of our modern computers. In fact, except for some models, it is normal that there is at least one fan necessarily inside our PC tower to cooling the internal components. Either in the processor, heatsink, memory, graphics card or in the boxes themselves. Since the beginning of the PC building, the cooling fan has been an integral part of our PC cabinet.

Models, like the 80mm ones, that were used in the past extensively, but now no longer last in our PC Case. However, the majority of tower fans are rarely used in cabinets. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally.The range of computer case fan sizes is huge from 40 to 200mm fans or even more than that. 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.
