Review: El performance de los ventiladores es muy bueno definitivamente cumplen con su función, tanto para servidores, NAS o para agregar un extra de ventilación a los headsync de la tarjeta madre funcionan a la perfección, el flujo de aire es bastante bueno y con bajo nivel de ruido. en comparación con la competencia NcTua, creo que valen cada peso de lo que cuesta el paquete de 5 es excelente y son PWM
Review: I have bought multiple packs of the 6K and used them all over. Imo I would say the difference in noise between these and a Noctua is fairly neglible so don't believe those that say these are insanely loud. I may be biased because I am replacing MUCH louder fans in old server equipment so anything quieter is a blessing, however I have tested the Noctua and the 6K version side by side in a quiet computer room of mine and even being next to them on full blast these were barely audible. I hooked them up to a bench top power supply giving 12V DC so there was no confusion of if they were each on full blast or if the noise was being muddied by other fans. I think the Noctua is a better pick if you absolutely value complete silence above all and you intend to use these in a computer that you have tuned to full blast. Otherwise with PWM I would pick these 100% of the time - they're much cheaper AND they move MUCH more air than the Noctuas, which is another great benefit in old server components -- I need the airflow. Ultimately these are a great buy and I would definitely recommend them!

## Features

- The S4028-6K's impeller is held in place by two ball bearings, making it both especially durable as well as less sensitive to external influences such as heat and dust
- The S4028-6K has a particularly wide speed range that can be regulated via PWM and voltage. With its 6000 RPM max it offers a well-balanced ratio between cooling power and noise
- With a static pressure of 4.2 mm/H2O and a maximum airflow of 12.06 m³/h, the S4028-6K is a true all-rounder and is suitable as both radiator and case fan
- The S4028-6K fits in 1U server cases as a replacement fan for routers, switches, and NAS. It can also be used for other products such as DVRs, Mini PCs, HTPCs, hard disk enclosures and 3D printers
- The fan has a standard 4-pin fan connector and can also be connected and controlled on 2-pin or 3-pin headers, while its 40 cm cable allows enough flexibility in positioning

*by T***T on 1 July 2024*

I got the Jonsbo TK-1 v2 case, but there weren't a lot of rooms for larger 120-140 fans. BUT THESE BAD BOYS CAME IN CLUTCH. There's some ventilation space on the left side of the case that I suspected these could fit in, AND THEY DID! Helped reduced my temp by quite a lot, I can feel them pumping out air as I ramp up performance and they do AN AMAZING job. The YouTube videos on them were rare albeit high quality and that's why I decided to stick with them instead of competitors. Running 4090 and 7950X3D and mewmaxxing on ultra + high every settings on Baldur's Gate 3 and Dota 2, but temps after were fantastical. Obviously water-cooling is a component here, but these fans did WORK to keep the internal of my chamber breezy. Will be buying more and stocking up for future builds. 10/10 🔥
