Three black 140mm square PWM case fans with 4-pin connectors and anti-vibration silicone screws

LORDWORLD

LORDWORLD 140mm PWM Case Fan 1700RPM 3-Pack Black

SKU CH-YJRC-C9N0H

Three 140 mm PWM fans with 4-pin connectors run up to 1700 RPM and include anti-vibration silicone screws

  • 140mm PWM fans adjust speed 5-12V for quieter cooling
  • 4-pin 2510 connector fits motherboard PWM headers and radiators
  • 12 anti-vibration silicone screws cut case resonance noise
  • Triple pack includes 12 standard screws for flexible mounting
  • Sleeve bearing design rated for long-life 1700RPM operation

140 mm PWM fan triple pack

This pack contains three 140 mm PWM case fans rated at 1700 RPM. Each unit uses a 4-pin 2510 connector and draws 0.21 A at 12 V DC. Sleeve bearings keep the fans running quietly inside standard computer cases, CPU coolers or radiator mounts.

Suited for 140 mm mounts with PWM control

Builders who need a trio of matching 140 mm fans for intake, exhaust or radiator duty will find this kit convenient. Anti-vibration silicone screws are included to reduce case resonance. Systems that only offer 3-pin headers or require a different frame thickness cannot use these fans without adapters or modifications.

1700 RPM maximum speed

The top speed of 1700 RPM is the key figure that determines airflow and noise ceiling. Running the fans at lower voltages between 5 V and 12 V lets you trade speed for silence, but the peak rating remains fixed at 1700 RPM.

Questions about this item

How much air does the 1700 RPM fan move in a typical case?

At 1700 RPM the 140 mm blade pushes a strong airflow through mesh panels or radiator fins, and PWM control lets the motherboard drop speed to near-silent levels when the system is idle.

What does the 4-pin 2510 connector actually control?

The fourth wire carries the PWM signal so the board can vary voltage between 5 V and 12 V, giving precise speed regulation instead of a fixed 12 V spin.

Will the 140 x 140 x 25 mm frame fit my chassis fan slots?

The fan matches the standard 140 mm square mounting pattern; the pack includes 12 standard screws and 12 silicone anti-vibration screws for either rigid or damped installation.
