Pros & Cons

Pros

  • ✓ Runs 2 PWM fans from a single motherboard PWM header
  • ✓ Frees up headers on boards with few fan connectors
  • ✓ Both fans follow one PWM curve for matched speeds
  • ✓ 100mm length keeps slack minimal for tidy routing
  • ✓ All-black sleeving blends into dark, windowed builds

Cons

  • ✗ Splits to only 2 fans; bigger fan arrays need a hub
  • ✗ 100mm may not reach fans at opposite ends of large cases
  • ✗ Shared signal means no independent speed curve per fan
  • ✗ Combined fan draw must stay within the header's current rating

Manufacturer description

The SilverStone CPF01 is a 1-to-2 PWM fan splitter cable that runs two PWM fans from a single motherboard PWM header. If your motherboard has fewer fan headers than your cooling setup needs, it adds a second fan without a separate fan hub or controller. Plug the CPF01 into any 4-pin PWM header, then connect two fans. Both fans get the same PWM signal, so they speed up and slow down together on whatever curve you set in BIOS or your fan-control software. That works well for paired intake fans, dual-fan radiators, or push-pull fans on a tower cooler, where you want matched speeds anyway. The…

SpecPicks Verdict

SpecPicks scored SilverStone Technology All Black Sleeved 1-to-2 Sleeved PWM Fan… using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. SilverStone's accessories 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 accessories 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.

Frequently Asked Questions

How many fans can I connect to the SilverStone CPF01?

Two. The CPF01 is a 1-to-2 splitter that connects two PWM fans to a single motherboard PWM header.

How long is the CPF01 splitter cable?

The cable is 100mm long. That suits fans mounted close together, like a dual-fan radiator or a push-pull CPU cooler. Fans far apart in a large case may need an extension.

Can I control each fan's speed separately with this splitter?

No. Both fans share one header's PWM signal, so they follow the same speed curve. If you need separate curves, connect each fan to its own header.

Will it work with 3-pin fans?

The CPF01 is designed for PWM (4-pin) fans on a PWM header. 3-pin fans usually physically fit a 4-pin connector but will not get PWM speed control. Check your motherboard manual to see whether the header supports DC voltage mode.

Is it safe to run two fans from one motherboard header?

Usually, as long as the two fans' combined current draw stays within the header's rated limit. Compare your fans' listed amperage with the header rating in your motherboard manual before connecting.
