“Fan case may tinh bao nhiêu cm” is a question that often pops up for PC builders, especially those focusing on optimal airflow and cooling. This translates to “What size case fan do I need?” in English. While it seems straightforward, choosing the right case fan size involves understanding your case’s compatibility, your cooling needs, and a bit of technical know-how. This guide will break down everything you need to know about case fan sizes, helping you make the best decision for your build.
Decoding Case Fan Sizes: What Does “Cm” Mean?
The “cm” in “fan case may tinh bao nhiêu cm” refers to centimeters, the unit used to measure the diameter of a computer case fan. Common case fan sizes include:
- 120mm: The most popular and widely compatible size, offering a good balance between cooling performance and noise levels.
- 140mm: Larger than 120mm fans, these provide higher airflow and quieter operation, often found in larger PC cases.
- 80mm: Smaller and less common, typically used as exhaust fans or in compact builds.
- 92mm: Similar to 80mm fans but slightly larger, also used for exhaust or in smaller cases.

Matching Fan Size to Your Case: Compatibility is Key
Before you even consider airflow or aesthetics, you need to make sure the fans you choose physically fit within your case. Most PC cases have designated mounting points for fans, with specific size support.
Here’s how to determine your case’s fan size compatibility:
- Consult Your Case Manual: The most reliable source of information is your PC case’s manual. It will clearly list the supported fan sizes for each mounting location (front, rear, top, bottom).
- Check the Manufacturer’s Website: If you don’t have the manual handy, the case manufacturer’s website will often have detailed specifications, including fan support.
- Measure the Mounting Holes: As a last resort, you can measure the distance between the mounting screw holes on your case. A 120mm fan will typically have holes spaced 105mm apart, while 140mm fans have a 125mm spacing.

Beyond Size: Factors Influencing Case Fan Choice
While size is a primary concern, other aspects factor into selecting the right case fans:
- Airflow (CFM): Measured in cubic feet per minute (CFM), this indicates the volume of air a fan can move. Higher CFM generally means better cooling.
- Static Pressure (mmH2O): This measures the fan’s force to push air through restricted spaces, like radiators or heatsinks. High static pressure is important for components with dense fin structures.
- Noise Level (dBA): Case fans produce noise, measured in decibels (dBA). Lower dBA ratings indicate quieter operation.
- Bearing Type: Different bearing types affect fan lifespan, noise, and performance. Common types include sleeve bearings, ball bearings, and fluid dynamic bearings.
- Connectivity: Fans connect to your motherboard through various headers, like 3-pin or 4-pin PWM (Pulse Width Modulation) for fan speed control.
Finding the Perfect Fit: Addressing Common Scenarios
Let’s address some frequently asked questions related to “fan case may tinh bao nhiêu cm”:
Q: My case supports both 120mm and 140mm fans. Which should I choose?
A: If you prioritize quieter operation and maximum airflow, 140mm fans are a good choice. However, 120mm fans offer a good balance and are more widely available.
Q: I want to install a liquid cooler. Does fan size matter?
A: Yes, radiators used in liquid coolers often have specific fan size compatibility, typically 120mm or 140mm. Choose fans that match your radiator size and provide good static pressure for optimal performance.
Q: I’m on a budget. Do I need to fill every fan slot in my case?
A: Not necessarily. Focus on achieving good airflow by having at least one intake fan (usually at the front) and one exhaust fan (usually at the rear). You can add more fans later as your budget allows.
Conclusion: Choosing Wisely for Optimal Cooling
Choosing the right case fans involves more than just understanding “fan case may tinh bao nhiêu cm.” While size is crucial for compatibility, airflow, static pressure, and noise levels also play significant roles in creating a well-cooled and efficient system. By carefully considering your case’s compatibility, your cooling needs, and the technical aspects of each fan, you can build a PC that runs cool and quiet for years to come.
