Fan Dimensions: 120mm x 120mm x 25mm. Home. What are the dimensions of a 120mm fan.
Premium quiet fan, 120x120x25mm, 12V, 4-pin PWM, max. 2000 RPM, max. 22.6 dB (A), >150,000 h MTTF. Next-gen A-series design combines high airflow and high static pressure performance, ideal both as a case fan and for CPU coolers, watercooling radiators and AIO liquid cooling systems.
In the majority of computers, the most standard fan sizes are likely to have 120mm x 25mm means 4.7 inches in diameter and 1 inch in width. While other computer case fan sizes like 180, 200 and 220mm fans are, specifically for big size PC towers.
The Noctua fan, for example, has 120 mm screw spacing despite being a 140 mm fan. So, now that you know how to measure PC fan size, let’s quickly run through a few key specs that will help you find a suitable fan for your needs. Airflow and Static Pressure.
Understanding the size and specifications will help you determine if it is compatible with your computer case and cooling needs. A standard 120mm case fan typically measures approximately 120mm x 120mm x 25mm. This measurement refers to the width, length, and thickness of the fan respectively.
Given that 120mm fans are generally better at static pressure and 140mm fans produce more airflow, it’s a great idea to use a mixture of both.Matching 120mm fans with radiators and heatsinks, and putting 140mm fans where airflow is unrestricted. On the subject of radiators, it’s important to note that you must match the radiator size to the fan size. 120mm fans are not compatible with a ...
The most common case fan sizes are 120mm, 140mm, and 200mm, but there are many other sizes available in the market. Choosing the right fan size depends on several factors, including case dimensions, compatibility, and airflow requirements.
The CORSAIR AF120 ELITE High-Performance 120mm PWM Fluid Dynamic Bearing Fan delivers PWM-controlled fan speeds from 400 RPM up to 1,850 RPM for powerful cooling, near-silent operation, and exceptional durability.
What size PC fan do I need? The PC size you need depends on many factors — computer case, heat levels generated by the components, and the preferred airflow or the CFM count. For instance, if you plan to build a full-fledged GPU-loaded gaming PC, a 120mm fan should be the minimum.
A 120mm case fan is a common and popular choice for many computer enthusiasts and builders. The width of a 120mm case fan, when converted from millimeters to inches, is approximately 4.72 inches. This fan size provides a good balance between airflow, noise level, and compatibility with most computer cases.
