Silent Wings 4 120mm PWM High Speed 2500 RPM Premium Low Noise Cooling Fan | 4-Pin | BL094: Case Fans - desertcart.com βœ“ FREE DELIVERY possible on eligible purchases Review: One of the very best airflow fans on the market - I was looking to get the best low-noise but high performance fan for the single output of my case to balance with the 4 low-noise fans I had running for air intake. 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. Review: Exceptional Case Fan - 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. ## Features - Silent Wings 4 120mm PWM high-speed is the fan of choice for all possible operations. Be it in a case, on radiators or heat sinks – Features like the silence-optimized fan blades and the funnel shaped fan frame make Silent Wings 4 120mm PWM high-speed a fan that makes no compromises between very quiet operation and highest performance. - Silent Wings 4 120mm PWM high-speed makes for extraordinary air pressure and, therefore, significant increases in the system’s performance. The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 120mm PWM high-speed allows the user to run even the most demanding applications. - Silent Wings 4 120mm PWM high-speed has 2 mounting options in the scope of delivery. The pre-installed anti-vibration mounting reduces noise-generating vibrations to a minimum. For radiators and heat sinks, the plastic mounting is the first choice. Both solutions have in common that they enable virtually inaudible operation at regular speed. - The key for virtually inaudible operation when needed 6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 31.2dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed. - The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours. In addition, it reduces the vibrations significantly and supports the virtually inaudible operation of Silent Wings 4 120mm PWM high-speed. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6WPZFBX | | Air Flow Capacity | 76.7 cfm | | Best Sellers Rank | #27 in Computer Case Fans | | Brand | be quiet! | | Brand Name | be quiet! | | Compatible Devices | Desktop | | Cooling Method | Fan | | Customer Reviews | 4.7 out of 5 stars 969 Reviews | | Global Trade Identification Number | 04260052188866 | | Item Dimensions L x W x H | 4.72"L x 0.98"W x 4.72"H | | Item Weight | 310 g | | Manufacturer | be quiet! | | Material Type | Plastic | | Maximum Rotational Speed | 2500 rpm | | Model | BL094 | | Noise Level | 31.2 db | | Number of Items | 1 | | Number of Packs | 40 | | Part Number | BL094 | | Power Connector Type | 4-Pin | | Product Dimensions | 4.72"L x 0.98"W x 4.72"H | | Set Name | PWM High-Speed | | Unit Count | 1 Count | | Voltage | 12 volts | | Warranty Description | 1 year | | Wattage | 2.4 watts | ## Product Details - **Brand:** be quiet! - **Compatible Devices:** Desktop - **Cooling Method:** Fan - **Material:** Plastic - **Maximum Rotational Speed:** 2500 rpm - **Noise Level:** 31.2 db - **Power Connector Type:** 4-Pin - **Product Dimensions:** 4.72"L x 0.98"W x 4.72"H - **Voltage:** 12 volts - **Wattage:** 2.4 watts ## Images ![Silent Wings 4 120mm PWM High Speed 2500 RPM Premium Low Noise Cooling Fan | 4-Pin | BL094 - Image 1](https://m.media-amazon.com/images/I/61fKd0gyi0L.jpg) ## Available Options This product comes in different **Color, Size, Set** options. ## Questions & Answers **Q: I enjoy this brand of fan but have a need for high cfm. which of the silent 4 120mm models yeilds the highest cfm?** A: The highest CFM 120mm model is the Silent Wings Pro 4 120mm PWM.

Is it just one?** A: Just 1. **Q: Silent wings pro 4 vs silent wings 4?** A: The Pro is more expensive and designed specifically for liquid cooling radiators. ## Customer Reviews ### ⭐⭐⭐⭐⭐ One of the very best airflow fans on the market *by A***N on November 13, 2024* I was looking to get the best low-noise but high performance fan for the single output of my case to balance with the 4 low-noise fans I had running for air intake.

These are pricey i am not going to lie but the quality and the performances in cfm you get in a fan thats this quiet is well then worth it, i had stock nzxt fans on my kraken elite and for what it was they did okay but i needed fans that push more air out and oh man do they do. In low idle i can feel the air blow through the radiator and my mesh upper portion of the case and this is just in low idle. I also want to put it out there that i run a 7700x and I’ve noticed that its been keeping my cpu temperature cooler by about 3-5 degrees. ## Frequently Bought Together - be quiet!
