Pros & Cons
Pros
- ✓ Runs three fans off one motherboard header; two cables chain up to five
- ✓ PWM signal passes to all three outputs for full speed control
- ✓ Fan 1 RPM returns to the header so monitoring still works
- ✓ 4-pin plugs accept 3-pin fans too, at 5V, 12V or 24V
Cons
- ✗ Only one fan's RPM is reported; the other two go unmonitored
- ✗ 13cm length is short for routing across a full-tower case
- ✗ 3-pin fans lose PWM control and fall back to voltage control
- ✗ You must check your header's current rating yourself before chaining
SpecPicks Verdict
SpecPicks scored Noctua NA-SC1 Sx2 using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies & cables category. Noctua'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-splitter cables for powering and speed-controlling three fans through a single header on your PC motherboard or other power sources (e.g. NV-PS1 power supply combined with NA-FC1 controller)
- RPM speed signal of one fan (output connector 1) is transferred back to the motherboard or fan controller for speed monitoring, PWM signal for speed control is transferred to all three outputs
- Works with Noctua 5V, 12V and 24V fans; 4-pin plugs supports both 3-pin and 4-pin fans (PWM-based speed control only with 4-pin PWM fans, 3-pin fans can be voltage-controlled)
- Set of 2, both 1-to-3 splitter cables can be combined to connect a total of five fans to a single header (verify not to exceed the maximum current rating for motherboard fan headers!) or PSU
- Trusted Noctua quality with black fibreglass silicone sleeving that is highly resistant against mechanical wear, heat and flames (up to 200°C, UL 1441 certified), safe for use in various environments
