Originally I had Fractal Design Dynamic GP14 fan that came with the case but I swapped that to be an additional input when I upgraded to a higher powered Corsair ML140 Pro. With the Corsair fan performance was decent but I found it seemed to get a bit noisy at moderate speeds.Realistically, my cooling setup was always more than adequate, I didn't have any temperature issues whatsoever, but I am a bit of a nerd for good air cooling and just like upgrading something once in a while and it seemed like there was room for improvement here.I had the corsair for several years but I would occasionally do research on fans or watch the latest reviews and comparisons of fans on youtube. Eventually the time felt right that I felt like spending the money and that there were some good options to upgrade to. This fan has been a definite improvement capable of moving more air at lower sound levels. I also like that it has the headroom to push to even higher speeds than I need with my current setup just in case I ever feel like it or was trying to max my performance having fun overclocking and benchmarking.I didn't bother to do any recorded tests of my temps but my subjective experience has been that I am very happy with the performance as I created a fan curve for it that gives me what I want airflow wise and my computer remains quieter than it did before. I also stepped away from having my computer with so many LED lights so the transition to a fan without lights worked for me. A few months ago I made significant upgrades to my processor and my video card and this still handles everything I can throw at it with ease and quietness. I have been super happy with the performance of this fan and will definitely have them in mind next time I am building a system. ### ⭐⭐⭐⭐⭐ Exceptional Case Fan *by on Reviewed in the United States August 18, 2023* I purchased the be quiet! Silent Wings 4 140mm PWM high-Speed fan to go in to the rear case position of my Fractal Define R5 case. Another review led me away from the Silent Wings Pro 4 as the user noted that it was loud at full speed and that it was optimized to go on to radiators which contributed to the extra cost of the fan. Upon receiving it I was shocked by the weight of this fan, nearly 11 ounces. Fit and finish appeared superb. Since I was only purchasing one fan, I was mostly price agnostic. I needed a rear case fan to use in combination with a Noctua NH-D15 cooler to help cool an Intel i9-13900K. It's plugged in to the CPU-OPT header on my MB which works well for my set-up since I don't game and don't put any stress on the GPU (CPU based video rendering.) The PC sits on my desk about 1.5 feet away from my ear. The PC is completely silent at idle with all the fans running at 30%. I get maximum cooling of the i9-13900K with the two Noctua heatsink fans plus the Silent Wings high speed set at 90% (about 1700 RPM for the be quiet! fan.) I get no throttling when working on my simple and short 4K videos and the sound level remains moderate even at 100% fan speeds for the 3 CPU fans. I have it mounted for silence which places the fan about 1 mm away from touching the case. This is how it arrives in the package. If you prefer, however, you can reverse the corner mounts and mount it touching the case for maximum air pressure. I'm using the 3rd party software FanControl to control all of my PC fans. I couldn't be more pleased with the performance of this fan. ### ⭐⭐⭐⭐⭐ Excelent *by on Reviewed in the United States June 6, 2026* I installed a new Main Board in my 18 yo mid-tower size case. This fan is perfect and MUCH quieter than the original constant RPM fan it replaced. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/650154969-be-quiet-silent-wings-4-cooling-fan-120mm-pwm-high](https://www.desertcart.co.za/products/650154969-be-quiet-silent-wings-4-cooling-fan-120mm-pwm-high) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-31*
