This article covers NZXT F120 RGB CORE [Black] PCケースファン RF-C12SF-B1 FN1919.

Overview

The NZXT F120 RGB CORE is a 120mm addressable RGB PWM fan that strikes an excellent balance between aesthetics and performance. With its semi-transparent blades that diffuse LED light evenly across the entire surface, this fan creates a stunning glow effect that elevates any PC build. The model number is RF-C12SF-B1 (product code FN1919), and it comes in a sleek black finish. Equipped with 8 individually addressable LEDs, the F120 RGB CORE can be fully customized through NZXT's CAM software, allowing you to create unique lighting patterns or sync with other NZXT components. Performance-wise, it delivers up to 78.86 CFM of airflow and 2.57 mmH2O of static pressure, making it versatile enough for both case ventilation and radiator duty. The fan speed ranges from 500 to 1800 RPM via PWM control, and the fluid dynamic bearing (FDB) ensures quiet operation with a maximum noise level of 33.88 dBA. Positioned as a mid-range RGB fan, the F120 RGB CORE offers excellent value for builders who want reliable cooling performance with attractive lighting at a reasonable price. It's a step up from basic non-RGB fans but more affordable than premium dual-sided RGB models like the F120 RGB Duo.

Compatibility Guide

Standard 120mm form factor (120 x 120 x 26mm) fits most PC cases with 120mm fan mounts, including ATX, microATX, and Mini-ITX builds. 4-pin PWM connector for automatic speed control via motherboard BIOS or software. RGB control requires a 3-pin addressable RGB header (5V/Data/GND) on the motherboard. If your board lacks this, you'll need an NZXT RGB Controller or a third-party ARGB controller. Compatible with standard 120mm radiator mounting (105mm screw spacing). * Low power draw (2.4W at 12V) means no additional power supply concerns.

Product Info

Released in early 2023, the NZXT F120 RGB CORE is sold as an official Japanese market product with a 2-year manufacturer warranty. Its price point of around ¥2,200–¥2,500 places it in the entry-to-mid tier of NZXT's RGB fan lineup. Market positioning: This is the most cost-effective RGB fan in NZXT's current lineup. While it has fewer LEDs than the F120 RGB Duo (which lights both sides), it delivers the same core airflow and static pressure performance. The CAM software integration is a key differentiator from generic RGB fans. Key specs: 500–1800 RPM (±180 RPM), 78.86 CFM max airflow, 2.57 mmH2O max static pressure, 33.88 dBA max noise, FDB bearing, 60,000-hour rated lifespan.

Best Use Cases

First-time RGB PC builder: The semi-transparent blade design creates a beautiful, diffused glow that's more refined than exposed-LED fans. PWM control keeps noise low. However, if your motherboard lacks an ARGB header, budget for a controller. Dual-purpose case and radiator fan: With balanced airflow and static pressure, this fan works well as a case intake/exhaust fan and on standard-thickness radiators (up to ~30mm). For thick radiators (45mm+), consider a higher-static-pressure fan. NZXT ecosystem builder: If you already own an NZXT case or RGB controller, this fan integrates seamlessly with CAM software for unified lighting control across all NZXT components. Quiet PC enthusiast: The FDB bearing ensures very low noise at idle speeds. At full 1800 RPM, noise reaches 33.88 dBA, which is still moderate. For absolute silence, cap the speed at 1200 RPM.

Things to Consider

Without a 3-pin ARGB header on your motherboard, the RGB functionality is unusable. You'll need an NZXT RGB Controller (sold separately) or a third-party ARGB controller. This is a single-fan pack. If you need multiple fans, the 3-pack version (F120 RGB Core 3-Pack) offers better value. The F120 RGB Duo has LEDs on both sides, making it look better when used as an intake fan (blades facing inward). If aesthetics from every angle matter, consider the Duo. If your case supports 140mm fans, the F140 RGB Core provides higher airflow. Check your case's fan compatibility before purchasing. ## FAQ
Q: Can I use this fan with an NZXT H510 Flow case? A: Yes, the H510 Flow has a standard 120mm rear exhaust mount that fits this fan perfectly. For front intake, the case uses 140mm fans, so consider the F140 RGB Core for that position. Q: Do I need CAM software to control the RGB? A: No. If connected to a motherboard ARGB header, you can use motherboard software like ASUS Aura Sync, MSI Mystic Light, or Gigabyte RGB Fusion. CAM is only required for NZXT-specific lighting effects or if using an NZXT RGB Controller. Q: Is this fan suitable for liquid cooling radiators? A: Yes, for standard 30mm-thick radiators. The 2.57 mmH2O static pressure is sufficient for most AIO coolers. For thicker radiators (45mm+) or high-density fin stacks, a higher-static-pressure fan like the NZXT F120Q is recommended.
