SickleFlow 200 ARGB Gen 2 Square Frame Fan, Customizable LEDS, Air Balance Curve Blade, Sealed Bearing, PWM Control for Computer Case

Quiet but moves good air when needs to. Very high quality!

These are a new 2025 release, but I'm honestly really surprised that these seem to have flown under the radar. Both their airflow and air pressure performance is exceptional. This made them perfect for my build as both AIO pull fans on a radiator as well as bottom intakes. At idle speeds their sound is also totally imperceptible, the first time I've ever heard that (despite using famously silent BeQuiet! fans, as seen in this case pictures as well). The aesthetic is incredible as well, this is the first single frame I've seen that looks both well composed and flashy enough without coming off as tacky. I was initially looking for reverse case fans (as most Lian Li O11 builds tend to use) but didn't really love any options. I came across this and was drawn in by the rare X-frame bracket, I really love the way that gives the case/fans some visual structure and I'm not sure why more fans don't use it (as opposed to the more common swirl-X frame bracket on the back). Highly recommend these!

Bought for a custom case build and am not disappointed. Super quiet at max speed. Rgb is as good as it can be. Setup in a push pull config they move a lot of air.

Quiet, moves a lot of air and looks good. Brought much needed life to an old haf 932 case

I've been using COOLER MASTER since the 1990's. Good product, nice and quiet.

Works fine! It's been running nearly constantly for a couple months and its quiet and does its job.

Todo al 100%. Son bastante buenos y silenciosos hasta 50%. Y pues es el límite que es tengo y mantienen mi pc por debajo de los 50 grados en un i3 14 gen, con refrigeración por aire.

Nice quality and look. Didn’t fit my installation though. Cool master case cover clearance wouldn’t allow it.
