## 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. 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.

### ⭐⭐⭐⭐⭐ FANTASTISCH!
*by S***D on August 29, 2023*

Let me just start by saying, these fans are GORGEOUS. Seriously, these are the best looking fans on the market by far and no other fan comes close. These just look so premium and expensive. They feel it too. These things are HEFTY for a PC fan. They just feel so solid and well built and genuinely feel like a product that's made to last.The cable these fans have is also just so unnecessarily nice. Yo, they for real SLEEVED the cable and gave it a plastic connector with the Be quiet logo on it. What?! Ain't no one EVER gonna see/feel that cable or the nice connector. But they did it anyways so the moment you install these for the first time you feel like you TRULY got your moneys worth. This is the sort of attention to detail you want from a high-end product!Alright, onto performance and noise levels.I've compared these fans to the Phanteks T30's, Noctua A12x25's, and the Corsair AF120 RGB Elites. These were the only fans I had lying around for testing. These blow the Corsair's so far out of the water I won't even spend time comparing the SWP4 to the Corsairs. Total knockout, three fold. These are better than the Noctua's. They spin much faster and sound quieter to my ears. No professional measuring equipment here, but these are damn nearly silent until about 1,600 RPM. The Phanteks are the better performers, but not by much. This is a given because they are 30mm thick versus 25mm on the SWP4. However, I only noticed a degree difference in GPU temps between the two. However, the SWP4 were quieter. Let's also not forget that the SWP4, being the slightly thinner fan versus the Phanteks, will have better compatibility with longer GPU's and smaller cases. I will gladly take a degree difference for a quieter fan that has slightly better overall compatibility.I love these fans so much that I ended up populating my entire system with them. They are truly worth the price simply because of the performance, build quality, noise levels, presentation, attention to detail, and nice additional accessories. For users looking for the 'One Fan to Rule Them All' fan, these are it.

### ⭐⭐⭐⭐⭐ The best fans hands-down
*by B***F on July 14, 2025*

No other fans come close if you value a quiet build. I can curve my fans quite high with these and still have minimal noise impact. The build quality is outstanding and they move plenty of air. I have three of these 140mm PWMs (two bottom intake, one top exhaust) and one high-speed 120mm PWM (rear exhaust) in an mATX case (Jonsbo z20) and it cools just fine. I may add one more top 140mm once price/inventory stabilizes just because there's room. They are not the cheapest fans by any means, but you get what you pay for, and in my opinion it's really not worth cutting corners on fans in general. Just do it.
