The ID-COOLING FS-04 PWM is a 1-to-4 fan splitter cable that connects up to four cooling fans to a single motherboard fan header. With shared PWM speed control and support for both 3-pin and 4-pin fans, it’s the simple way to expand your cooling when your motherboard runs short on fan headers.

1. 1-to-4 Fan Splitting

With one input and four outputs, the FS-04 PWM lets you power and run four fans from a single header. It’s an easy fix for builds with more fans than available headers, keeping all of them driven from one connection point on the motherboard.

  • Connects up to four fans to one header
  • Standard 4-pin input and four fan outputs
  • Ideal for boards with limited fan headers

2. Shared PWM Speed Control

All connected fans follow the same PWM signal from the motherboard header, so they ramp up and down together in response to temperature. Your board reads RPM from one output while every 4-pin fan on the splitter shares the same automatic speed control for consistent, temperature-aware cooling.

  • Automatic PWM speed control across all fans
  • Fans scale together with system temperature
  • RPM reported to the motherboard from one output

3. 3-Pin & 4-Pin Fan Compatibility

The FS-04 PWM works with both 3-pin and 4-pin fans, so you can mix whatever hardware you have. 4-pin fans get full PWM speed control from the shared signal, while 3-pin fans connect for power and run at a steady speed.

  • Compatible with 3-pin and 4-pin fans
  • Full PWM control for 4-pin fans
  • Powers 3-pin fans at a steady speed

4. Clean, Easy Cable Management

Consolidating four fans onto a single header cuts down on cable clutter and frees up your other headers for different uses. Just plug the fans into the splitter and the splitter into your board — simple, tidy, and quick to install.

  • Frees up motherboard fan headers
  • Reduces cable clutter for a tidier build
  • Simple plug-and-play installation

Frequently Asked Questions

How many fans can I connect?
Up to four — the splitter runs four fans from a single motherboard fan header.

Can I control fan speed?
Yes — all 4-pin fans share the header’s PWM signal and scale together with temperature. Your motherboard reads RPM from one of the outputs.

Does it work with 3-pin fans?
Yes — 3-pin fans connect for power and run at a steady speed, while 4-pin fans get full PWM control.

Is there a limit on how many fans it can power?
The splitter supports up to around 1A of total fan load across all four ports — comfortably enough for typical case fans. Check your motherboard header’s rating for heavier fans.
