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: I exclusively use be quite fans on PC builds have not had a failure yet - Great 120mm fan choice, quite when at lower RPMs, and move a lot of air when turned up. I exclusively use Be quiet fans and have not had a failure yet. Thick material on the fan and blades, quality look and feel, mounting hardware is quality and the power cables look great.

### ⭐⭐⭐⭐⭐ Best 140mm silent fans on the market
*by M***H on October 1, 2025*

I’ve tried a lot of high-end fans from Noctua, Phanteks, Lian Li, Arctic, etc, and I was really surprised with how good the SWP 4’s are. In some ways IMO they are one of the best 140mm fans on the market, if not thee best. Let me explain why. In terms of brands the two best fans I’ve ever used are the Noctua NF-A12 G2’S and the Phanteks T30. Like the SWP 4’s they both strike the perfect balance between high airflow and silent operation. HOWEVER, the reason why I ended up going with the SWP 4’s is because (1) the Noctua G2’s only come in their distinctive yet fugly brown color, and (2) Phanteks still hasn’t released a 140mm version of the T30. So essentially, if you need black 140mm fans that are both high performing and silent, the SWP 4’s are currently the best option on the market today. They’re also a very attractive fan with high quality cabling so if you’re into aesthetic building like I am they look great on a radiator. In terms of how quiet they are, I have them in my SFF PC which sits directly on my work desk and while idle my PC is completely silent. But even at higher RPM my PC sounds similar to an air purifier - no vibrations, motor sounds, droning, etc, just a pleasant and subtle rush of air akin to white noise. Overall I definitely recommend these fans especially if you need 140mm.
