Choose Lian Li for a visible RGB build or Noctua for understated styling and a simpler setup. Cooling depends on the case, radiator, fan curve and system layout, so published specifications are comparison points, not guarantees.

Are Lian Li UNI FAN SL-INF fans good for Black Friday builds?

Lian Li UNI FAN SL-INF 120 Triple Pack Black suits a three-fan RGB build, with three 120 mm fans and a controller included. Its linked design simplifies connections, and infinity-mirror lighting stands out through a clear side panel.

Check connection requirements and case layout, especially when adding the fans to an existing hub.

Is Noctua NF-A12x25 worth choosing over RGB fans?

Noctua NF-A12x25 PWM chromax.black.swap offers a black 120 mm frame, PWM control and a published 22.6 dBA noise rating. Noctua also offers Noctua NF-A12x25 PWM in brown and beige, Noctua NF-A12x25 FLX with manual speed adapters, and Noctua NF-A12x25 ULN for lower-speed operation.

These models lack the lighting of Lian Li UNI FAN SL-INF fans. Choose by finish and control method, and check motherboard headers and cooling needs before selecting a slower model.

What should you check before buying a 120 mm or 140 mm PC fan?

Match the fan to the case, radiator or cooler mount. Lian Li UNI FAN SL-INF 120 and Noctua NF-A12x25 models fit 120 mm positions; Lian Li UNI FAN SL-INF 140 Single Pack Black requires a 140 mm position.

Check power and lighting connections, radiator clearance, and intake or exhaust direction. Noctua PWM models use PWM control, while Noctua NF-A12x25 FLX includes manual speed adapters. Lian Li UNI FAN SL-INF RGB models add controller requirements, and pack contents vary.

Which fan type offers better value for a 2026 PC build?

Value depends on fan count, lighting needs and included hardware. Lian Li UNI FAN SL-INF 120 Triple Pack Black includes three RGB fans and a controller; Noctua NF-A12x25 PWM chromax.black.swap is a straightforward single-fan option.

Compare the number of fans required and the package contents. Choose a triple pack for a new build or a single fan for a replacement. Without RGB, compare Noctua NF-A12x25 PWM, Noctua NF-A12x25 FLX and Noctua NF-A12x25 ULN by control method and speed.
