Reviewed in Canada on April 12, 2025Verified PurchaseParfait
- Reviewed in Canada on August 18, 2024Verified PurchaseGreat when you have a large motherboard/case and requires further reach. Worked for me when the fan splitter could not reach during the build. Great when daisy chaining groups of 3 (120mm Fans). I had plenty of fan headers so grouping 3 with a splitter then attaching an extension worked well.
- Reviewed in Canada on May 18, 2024Verified PurchaseI had to use Two of these cables per each fan. So 24" extension total per fan and they work just fine.
Much cheaper than buying individual 24" fan extension cables that are expensive.

- Reviewed in Canada on February 17, 2024Pros:
Length and Flexibility: The 12-inch cables offer ample extension for reaching distant fan headers, particularly behind the motherboard tray. The mesh sleeving provides flexibility while preventing kinks.
Build Quality: Sturdy construction with firm connectors and durable sleeving. These cables will last.
Versatility: These extensions work with both 4-pin PWM and 3-pin fans, offering wider compatibility. The included keying prevents accidental misconnections.
Aesthetics: The black sleeving and rubberized ends blend well with most PC builds. They're a visible upgrade over stock fan cables.
Value Pack: The 4-pack provides spares for future builds or sharing with friends, making it a cost-effective option.
Cons:
"Off" Feeling: Some users report a strange sensation when turning the fans on/off, although functionality remains unaffected. It's unclear if this is widespread or an isolated case. I've never experienced it.
Thinness: Compared to brand-name fan cables, these might feel slightly thinner. However, this doesn't seem to impact performance or durability.
Not a Splitter: While they extend reach, these cables don't power additional fans. Use a splitter if you need to connect multiple fans to one header.
Overall:
These extensions offer a solid solution for extending fan connections while maintaining performance and aesthetics. The build quality and versatility are commendable, and the value pack is a bonus. However, the slightly thin cables might be minor drawbacks for some. If you prioritize a reliable and affordable extension solution, these are definitely worth considering. Just be aware of the potential quirks and choose a splitter if you need to power additional fans.
- Reviewed in Canada on July 1, 2024Verified PurchaseGood value for money
- Reviewed in Canada on May 10, 2024I only needed one of these cables for my setup. For some reason one of the system fans ports are above the PCIE x16 which isn't easily accessible through my rig. While I can directly plug in the fan cable to the mobo, I would like some extra slack to better cable manage at the back. Anyway, it is an extension cable and so the attachment process is really simple. The cable is sleeved and has a heatshrink wrapping on the ends for added durability.
- One thing I don't like is the spaghetti colours which are ever so slightly visible on the end that connects to the motherboard.
Nevertheless, it is again, cheap and serves its purpose, which is really all you need.

5.0 out of 5 stars Nicely priced and very high quality fan cables for PC builds
Verified PurchaseValue-priced but high quality PC case fan extension cables. Certainly beats how much my local Microcenter charges for the same cables. And these that I got from amazon appear to be of a higher quality.
It's all just cables anyway. Perfectly functional for my basic PC builds. Connect multiple 120 and 140mm PWM fans to fan headers in ATX and mATX motherboards.
Works. Nicely priced. I will order more for future PC builds.

5.0 out of 5 stars Sehr gutes Preis / Leistungsverhältnis
Verified PurchaseIst genau das was es sein soll, eine Verlängerung, die Stecker sitzen gut und, auf den ersten Blick, scheint, die Qualität auch in Ordnung zu sein.
