Pros & Cons
Pros

Cons
- ✗ Splits one header, so both fans always share the same speed curve
- ✗ Only doubles a header, no 3-way or 4-way splitting option

- ✗ Adds a junction and slack cable to route inside tight cases
Manufacturer description
The Noctua NA-SYC1 chromax.Black solves a problem every dense build eventually hits: more fans than fan headers. Each set includes three NA-YC1 y-cables that split a single header into two, so you can run a pair of fans from one motherboard connection instead of hunting for a free port or adding a hub. Because the cables carry the full 4-pin PWM signal, both attached fans respond to the same speed curve simultaneously rather than running locked at 100 percent, and the 4-pin connector stays backward compatible with 3-pin voltage-controlled fans. The black sleeving is the chromax treatment…
SpecPicks Verdict
SpecPicks scored Noctua NA-SYC1 chromax.Black using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Noctua's cooling & fans 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 cooling & fans 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 run with this set?
The pack contains three y-cables, and each one splits a single fan header into two connections, so a full set lets you run six fans from three motherboard headers.
Will both fans still be PWM controlled?
Yes. The cable carries the 4-pin PWM signal to both fans, so two 4-pin PWM fans on one header are controlled simultaneously by the same curve rather than running at full speed.
Does it work with 3-pin fans?
Yes. The 4-pin connector supports both 3-pin and 4-pin fans, so you can use it with older voltage-controlled fans as well as PWM models.
Can I set different speeds for the two fans on one cable?
No. Both fans share one header and therefore one control signal, so they always run the same curve. Use separate headers if you need independent speeds.
What warranty comes with these cables?
Noctua covers the NA-SYC1 with a 6-year manufacturer's warranty. Check the product listing for current terms and regional coverage details.
