This little guy moves ALL the air
Needed a solution for a RAID Controller (PERC H730) that was continually running at 52c in a Fractal Design Node 304 case. Designed and 3D Printed a bracket for it, installed on the same port as the rear fan so it's cranked up pretty good. It's almost silent, and took my temps down to 38c continuous. Absolutely worth the cost.

Silent and powerful
My PC's CPU temperature was low (35 – 52 degrees). However, the Z690 chipset was hovering around 80 – 90 degrees. Way too hot for my comfort. Made a simple mod by zip tying a 4cm Noctua fan to blow directly at the chipset heatsink. The temperature drops to between 61 and 69 degrees. ASUS made a mistake of removing the heatsink fan for aesthetic reason.

Excelente calidad 👍
Excelente producto al inicio pensaba que era demasiado caro para un ventilador tan pequeña, pero de verdad que sí fama lo precede. Lo instale en una impresora 3d y me va de maravilla comparado con el que traía este es mucho muy silencioso, la verdad estoy muy satisfecho con la calidad de este producto
