Key specs explained for this fan
Fan Size: 120mm
This measurement defines the physical footprint of the fan. You will find this size fits standard 120mm mounting holes found in most PC cases. It offers a balance between airflow volume and static pressure. If your case supports 120mm mounts, this fan slides in without adapters. Larger fans move more air, while smaller ones fit tighter spaces. This size is the industry standard for general case ventilation.
Bearing Type: Fluid Dynamic Bearing
This describes the internal mechanism that supports the fan shaft. Fluid dynamic bearings use a lubricant layer to reduce friction. This design typically results in quieter operation and longer lifespan compared to sleeve bearings. You benefit from smoother rotation and less vibration over time. When shopping, look for this spec if you prioritize low noise levels. It is a reliable choice for continuous operation in enclosed computer cases.
Width: 7 inches
This dimension indicates the overall width of the fan unit including the frame. You need to check your case specifications to ensure this width fits within the mounting area. A 7-inch width is standard for 120mm fans, allowing it to align with existing screw holes. Verify that nearby components do not obstruct this space. Proper clearance ensures the fan sits flush and operates without interference from other case parts.
Height: 2 inches
This measurement shows the depth of the fan from front to back. You must ensure your case has at least 2 inches of clearance depth. This space allows the fan to sit properly without touching the back panel or radiators. Insufficient depth can cause vibration or prevent installation. This standard height works with most mid-tower and full-tower cases. Always measure the available depth before purchasing to avoid fitment issues.
Length: 6 inches
This value represents the length of the fan unit. It corresponds to the standard 120mm mounting pattern when converted to inches. You use this to verify compatibility with your case's fan trays. Most cases are designed for this specific length. If your case uses different dimensions, this fan will not fit. Check your case manual for exact mounting dimensions. This spec ensures the fan aligns correctly with the chassis structure.
