Review: A bit loud, but performant - These fans are a bit louder than I would have hoped for, but they're still quieter than what they replaced. I did some math before buying and determined that the 6K variant would not be enough for my use case on a Tesla P40. That was correct, as these fans have to be at 11-12K RPM to keep temperatures under control. Under a more moderate load, they can run at 9K or less to keep it cool. Overall, if you're trying to cool a 250W TDP or so GPU like a Tesla P40, these work fairly well for the price.
Review: Wow - These fans sucks so much, it could suck a golf ball through a garden hose! In all seriousness, it is loud on full speed but it moves more air than any off brand fan I've purchased. It is quiet on the low settings.

## Features

- TheS4028-15K's impeller is held in place by two ball bearings, making it both particularly durable and less sensitive to external influences like heat and dust
- The S4028-15K has a particularly wide speed range that can be regulated via PWM and voltage. With its 15000 max rpm it is one of the strongest 12 V fans with a 40 mm diameter
- With a static pressure of 26.5 mmH₂O and a maximum airflow of 32.67 m³/h, the S4028-15K is a true all-rounder and is suitable as both a radiator and case fan
- The S4028-15K 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 the 40 cm cable allows enough flexibility in positioning

## Questions & Answers

**Q: are these silent or the standard howling?**
A: They aren’t silent but they are at least 90% quieter than the standard screamers. A point to note is that on the servers I've used these the cpu temps can be around 10-12c hotter than using the screamers so watch out for that. They move significantly less air.

### ⭐⭐⭐⭐⭐ Wow
*by I***K on November 12, 2023*

These fans sucks so much, it could suck a golf ball through a garden hose! In all seriousness, it is loud on full speed but it moves more air than any off brand fan I've purchased. It is quiet on the low settings.

### ⭐⭐⭐⭐⭐ Fantastic replacement for 3-pin Fan
*by W***S on April 8, 2024*

Originally was using another pair of 40x40x28mm fan that came with my In-Win 1U case. Was running at max speed since it was 3 pin. Bought a couple of these Arctic fans since they were 4 pin and have been working out great. Have them running at approximately 6-7,000 RPM and they are decently quiet for behind a closed door. It’s nice to have the ability to go back up to 15,000 RPM if necessary but I think the temps will be fine running at ~60% speed. Screws fit fine with the pre-existing screws from my old fans, but be careful screwing everything back on. I accidentally cracked a corner of one of these Arctic screws but obviously it’s still fine.
