Pros & Cons

Pros

  • ✓ Runs 3 case fans off one motherboard header, freeing headers for other components
  • ✓ PWM signal passes to all 3 fans, so speeds stay synced under motherboard control
  • ✓ Master connector returns RPM tach to the board so BIOS still reads fan speed
  • ✓ 12-inch sleeved black cable reaches nearby fans without adding slack to route

Cons

  • ✗ 12 inches is short for top-to-bottom runs in a full-tower case
  • ✗ Only the master fan reports RPM; the other two show nothing in software
  • ✗ All 3 fans share one curve, so no per-fan tuning from this splitter
  • ✗ Three fans on one header can exceed the header's amperage rating on some boards

SpecPicks Verdict

SpecPicks scored Cable Matters 2-Pack 3 Way 4-Pin PWM Fan Splitter Cable using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies & cables category. Cable Matters's power supplies & cables lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power supplies & cables of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Key Features

  • Triple Fan Connection Solution: The 4 pin fan splitter cable connects up to 3 computer case fans to a single motherboard fan header. This PWM splitter cable lets you add an additional fan to improve airflow inside your PC. A fan speed label on the 4 pin master connector of the fan header splitter is wired to receive the PWM control signal and distribute it to all slave fans for synchronized cooling.
  • Unified PWM Control: The 3 way fan splitter (also known as a motherboard fan splitter, CPU fan splitter, or PC fan splitter 4 pin) connects to a 4-pin motherboard header and splits the signal across 3 PWM fans. Control fan speed uniformly through motherboard software for efficient, balanced cooling performance.
  • Synchronized Speed Management: The 4pin fan splitter features one 4-pin connector that sends the RPM signal back to the motherboard to synchronize fan speed across the other two fans. The 3 pin fan splitter omits the RPM signal pin, allowing all connected fans to run in tandem when supported by your system—perfect for setups where you need to daisy chain PC fans for optimized airflow.
  • Spare Cable Convenience Pack: This cost-effective 2-pack of computer fan splitter 4 pin cables includes a spare for future upgrades or extra fans. Each sleeved and wrapped black 12-inch case fan splitter cable provides a clean, professional look inside an open PC case and helps organize your cable management.
  • Wide Compatibility for Enhanced Cooling: Compatible with both 3-pin and 4-pin fans, this PWM fan splitter cable works with popular models such as the Cooler Master Hyper 212 EVO 120mm, Cooler Master MegaFlow 200mm, and other large 230mm case fans. Easily expand your system’s cooling capacity with this reliable PWM fan splitter cable.
