Worth the money, especially when you look at the price of the fan on it's own. Review: Quality made - Nice addition to my build ## Features - Upgrades the NH-U12S redux to a push/pull dual-fan configuration for improved performance or lower noise levels when running both fans at lower speed - Can reduce temperatures by 1-3°C, especially on higher heat-loads such as during turbo use, on overclocked systems or higher TDP processors - Second high-quality NF-P12 redux-1700 PWM fan supports automatic speed control via the motherboard, can provide massive airflow at load and run whisper-quiet at idle - Low-Noise Adaptors allow the maximum fan speed to be reduced from 1700 to 1300rpm for near-silent operation - Includes 1x NF-P12 redux-1700 PWM fan, 4 anti-vibration pads, 1 pair of fan mounting clips, 1x 4-pin PWM y-cable and 2x Low-Noise Adaptors ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08WQ6HT24 | | Best Sellers Rank | 89,434 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 395 in Kids' Play Trucks 19,270 in Camping & Hiking | | Brand | Noctua | | Compatible Devices | Desktop | | Cooling Method | forced air | | Country Of Origin | Taiwan | | Customer Reviews | 4.8 4.8 out of 5 stars (926) | | Included Components | 1 product | | Item Dimensions L x W x H | 15.4L x 13.9W x 4.9H centimetres | | Item Weight | 0.1 Kilograms | | Manufacturer | Noctua | | Manufacturer Part Number | NA-FK1redux | | Material | Fibre-glass reinforced PBT | | Max Rotational Speed | 1700 RPM | | Model Number | NA-FK1redux | | Number of Items | 1 | | Power Connector Type | 4-Pin | | Product Warranty | 6-year manufacturer’s warranty | | Voltage | 12 Volts | ## Product Details - **Brand:** Noctua - **Compatible devices:** Desktop - **Cooling method:** forced air - **Manufacturer:** Noctua - **Material:** Fibre-glass reinforced PBT - **Maximum rotational speed:** 1700 RPM - **Number of Packs:** 1 - **Power connector type:** 4-Pin - **Product dimensions:** 15.4L x 13.9W x 4.9H centimetres - **Voltage:** 12 Volts ## Images ![Noctua NA-FK1 redux, Second Fan Upgrade Kit for NH-U12S redux Cooler - Image 1](https://m.media-amazon.com/images/I/81L6v6TLrpL.jpg) ![Noctua NA-FK1 redux, Second Fan Upgrade Kit for NH-U12S redux Cooler - Image 2](https://m.media-amazon.com/images/I/81YTWX0VJGL.jpg) ![Noctua NA-FK1 redux, Second Fan Upgrade Kit for NH-U12S redux Cooler - Image 3](https://m.media-amazon.com/images/I/81hu8euJwoL.jpg) ![Noctua NA-FK1 redux, Second Fan Upgrade Kit for NH-U12S redux Cooler - Image 4](https://m.media-amazon.com/images/I/71oFcQTJ5xL.jpg) ![Noctua NA-FK1 redux, Second Fan Upgrade Kit for NH-U12S redux Cooler - Image 5](https://m.media-amazon.com/images/I/81gJvJ0-AVL.jpg) ## Questions & Answers **Q: Would these fan clips work for the u12p? I have the heat sync but no fan clips. Since im not the original owner I cannot get them from noctua.** A: Since this was designed as an add on fan for the Noctua NH-U12S redux cooler, the clips will be compatible with the other Noctua NH-U12S coolers. Diagrams of these coolers can be found at the Noctua website showing the exact dimensions. **Q: Does the fan have a cfm rating? (i don't see cfm on noctua.at specs)** A: This is a replacement part for the u12s cooler which commonly has a fan of a cfm rating of 70.60 so I'm guessing that's it **Q: Hi,does it work with cooler master hyper 212 evo ??** A: yeah but you'll need the brackets that came with the 212 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not quite 20% cooler ;) *by E***A on 9 January 2026* 2-3*C cooler. Worth the money, especially when you look at the price of the fan on it's own. ### ⭐⭐⭐⭐⭐ Quality made *by J***C on 21 May 2025* Nice addition to my build ### ⭐⭐⭐⭐⭐ Worthwhile Accessory *by K***N on 16 May 2021* I picked this up to add to my NH-U12S Redux air cooler. It will only drop temperatures a few degrees more, but I had room for it in my case so wanted to add it. As you would expect from Noctua, it arrives in a nice box and comes with a fan splitter cable, two low noise adapters and the metal grips to attach the fan to the cooler. The fan fits perfectly and isn't too loud either.
