be quiet!Pure Wings 3 120mm PWM High-Speed Case Fan | Speed-regulating Closed Loop Motor| Extraordinary Air Pressure | Very Quiet Operation | BL106

I have been using the original Thermalright Frozen Prism 240 Black AIO 120mm fans, which were pretty good. Unfortunately 1 of them went bad and started making a loud grinding noise, despite nothing touching the blades.I picked up two of these Pure Wings to replace the bad fan as well as the other Thermalright, and I have to say both the airflow and noise level are noticeably improved. My CPU temperatures are a little lower on average (about 2 to 3 degrees centigrade) when playing Cyberpunk 2077 or working in really demanding office files. The fans typically run between 55% and 75% during my office tasks, and they ramp up to 100% generally when gaming. Even then, the sound is a pretty soft hum. It's noticeable if I lower the volume on everything, but when playing at a normal volume or with my headphones on I never notice the sound. The sound is certainly less noticeable than my GPU fans, which are quite loud above 70%.I can't comment on their lifespan yet. The first couple weeks of using these fans has been great, so if they continue this way I will be quite happy.

So, I installed this fan to replace some RGB nonsense fan that was installed. It was so much louder than the fan I was replacing, I was so disappointed. I even started a return and called beQuiet to complain. Then I thought, well, I'll just put the old fan back in. In the process of uninstalling the Pure Wings 3, I thought I would just plug it in to power while it's outside of the case, to see if maybe it was experiencing interference when installed or if it was always noisy. Well, when I plugged it in, I felt a nice breeze from the fan and very little sound. 😌 I then put it back in the case to see if it was still noisy when installed. It turns out, I had installed it backwards and it was pushing against 5 other fans and rightfully crying out for help! Nice and quiet now that it's flipped around. Don't be like me!! Install in the correct orientation!

Item came fast item is as described comes with 4 mounting screws and 4 pin motherboard connector buld quality seesm just fine yet to install on new build

I'm really impressed at low rpm how much air flow is moving while the fan is near silent. I have nothing negative to say

This fans were for my small form factor build in the ncase t1. I use these on a radiator, the radiator places the fans within 1mm of the case panel. With the panel on it creates a lot of wind noise, with the side panel off it is significantly quieter but still creates wind noise between the fan and the radiator. Overall though the fans are quiet. I feel like if they were used just as case fans they would be dead silent but as a radiator fan or against a panel it creates too much turbulence.

Fantastic fans, very good quality, and awesome performance. Unbelievable for the price

Beautiful product and cant say nothing bad about its performance! Greatly recommended.

I bought a pair of these and I love how quiet they are. Even at full speed I can't really hear them.However, thermals were surprisingly poor. I moved them around (4 fans total) but all other configurations were worse than the original.I opted for a pair from a manufacturer that starts with a 'C', same CFM and all, and it's now much better.I moved these to a much smaller case and they seemed to do better there. I still like them, just not for my bigger case.
