Questions about this product
- How thin is this fan and will it fit a tight case?
- It's a 120mm fan with a 15mm slim frame, versus the usual 25mm thickness. That extra 10mm of clearance makes it fit small form factor builds and dense layouts where normal fans won't. Measure your available depth before ordering.
- What headers do I need for the fan and the lighting?
- The fan uses a 4-pin PWM connector for automatic speed control. The lighting runs on a separate 5V 3-pin ARGB header for addressable, software-synced effects. You'll need both headers free on your motherboard to use every feature.
- How fast does it spin and is it loud?
- PWM adjusts the speed across an 800 to 2400 RPM range. At low load it stays quiet, then ramps up when components heat up. Airflow and noise figures aren't published, so judge final loudness by your fan curve and case.
