Fans are often overlooked when building a gaming PC for the first time, keen to invest in video cards and CPUs its easy to forget how you’re going to keep your new rig cool – but reducing temperatures and noise
are essential, and Noctua’s Redux fans are pretty good at both.
While most of Noctua’s fans boast the retro brown and beige color scheme, the offerings in the Redux product line are a distinct light grey color.
Redux fans are available in a range of sizes and speeds, from 140mm to 80mm, and have been designed by Noctua to appeal to budget builders and hardware fans, offering most of the technologies of their more expensive cousins, but at a cheaper price.
These are all PWM (pulse width modulation) fans, and range in speed from 1600RPM, 1500RPM and 1800RPM respectively.
If you’re new to PC building and are wondering what PWM fans are, it’s simple.
They’re basically fans that can have their speed controlled by your motherboard, depending on the temperature inside your case, and using software like SpeedFan.
As with all of Noctua’s hardware the Redux fans are well packaged, and despite being from the firm’s so-called ‘budget’ line, are presented as a high quality product.
The NF-B9 is a 92mm fan that features an industry standard SSO-bearing, and a mean-time between failure (MTBF) rating of 150,000 hours – basically this means it’s super reliable.
This reliability is confidently backed by Noctua’s six-year warranty on the fan – a term almost unheard of for a PC case fan.
The NF-B9 PWM features proprietary automatic speed control through its custom-designed smooth commutation drive (SCD) technology.
This provides much smoother torque impulses and means PWM switching noises are reduced, allowing it to strike a balance between very strong cooling performance and low-level noise operation.
The seven fan blades feature bevelled blade tips and vortex-control notches.
These contribute a wider surface area of fan blade to dissipate heat, and spread the fan’s noise emission over a range of frequencies – effectively making it more pleasant to listen to – yes, they really have paid VERY close attention to detail in producing this quality piece of kit.
Unlike other fans in this post, the 140mm NF-P14R fan features a round frame, but with 120mm mounting holes allowing it to be fitted into a smaller space.
This means it provides more airflow due to its larger size, but will fit in all 120mm mounts.
While the NF-B9 features seven fan blades, the NF-P14R features nine, providing great airflow to your components.
The fan also features Noctua’s time-tested SSO-bearing, with a 150,000 MTBF rating, and Noctua’s six-year warranty.
The top speed of the NF-P14R is 1500RPM making it ideal for a variety of uses, including case, radiator and CPU cooling.
As with other products in the Redux line, the fan features vortex-control notches, ensuring that even at full speed the noise generated by the fan is extremely low.
The smallest fan in the Redux range at just 80mm, the NF-R8 features a seven-blade design, and a top speed of 1800RPM.
It also features Noctua’s custom speed control technology, that integrates smooth commutation drive technology to ensure the noises produced when the fan changes speed remain extremely low.
Again, the fan features an SSO-bearing, that has a 150,000 MTBF rating and a six-year warranty.
Each of the fans comes with mounting screws and is extremely simple to install
I installed each Redux fan in my test system then put them through their paces running the Witcher 3 at maximum settings on a GTX 1080Ti at 4K.
The fans each remained whisper quiet even under full load, which is great news for hardcore gamers.
But if you’re more of a casual gamer, and mainly use your PC for work or surfing the internet, you’ll barely notice these fans are on.
This makes them a perfect choice for mini-ITX builds or a rig you’ve designed to sit under your TV in the living room.
If you’re building a gaming PC, first make sure you don’t overlook cooling, second make sure you consider Noctua’s excellent line up. Recommended.
