GDSTIME Graphic Card Fans, Graphics Card Cooler, Video Card Fan, PCI Slot Dual 90mm 92mm Fans, VGA Cooler

You get $6 worth of components - $2 mounting PCI bracket made from soft bending metal and 2x$2 fans. The fans appear to be PWM and they don't work when connected to a PC motherboard or fan controller. I have not been able to find the datasheets and figure out what frequency they operate under, so I threw them away after about two hours of trying to get them work with arduino. The supplied molex adapters are useless because the fans don't have standard +12 V, GND and tach lines; they're 3-pins but they require PWM input at the right frequency. They're basically very old noisy fans. Save your money and get the mounting bits separately and get 92mm or 80mm fans.

This fan fit right into a slot and the 3-pin plug fit fine into a 4-pin fan plug on my motherboard (ASRock Taichi x399), and I am able to control the speed via my motherboard fan control utility. The fan is very quiet at full blast and almost silent at lower speeds, and moves good air. This is my work PC so I wanted it to be silent, and so I bought a graphics card that only has a passive heatsink, no fan. But when playing games it gets too hot to touch and slows down. So I bought this fan to try to keep the heat under control only during those times that I play games (very rarely). Wow what a big difference! After 20 minutes of game play the graphics card heatsink is barely warm, an enormous difference from the previous too hot to touch! So in short, this fan works as advertised. It includes a power adapter for the older style (round pin) power plugs used on older hard disks and some instructions for splicing it into an existing plug. I'm a little surprised that the adapter isn't for more modern SATA style power plugs. It includes a one page instruction sheet that tries to pack some good technical info into few words and not the clearest english ever, but I suspect in 99% of the cases the instructions aren't needed anyway as this will likely just plug right in to any modern motherboard with a free fan plug, or any PC power supply using the included adapter. So in short, it fits as advertised, plugs right in, is quiet, moves lots of air and works great with the motherboard built in fan controller if you have one, or plugs in with the included adapter if needed.

Tenía dudas de adquirirla, pero además de que me llegó muy rápido (como 15 días antes de lo previsto), SI FUNCIONA! uso una EVGA RTX 2060 OK, y antes con CAll of Duty Warzone y pantalla 2K a full, subía a 84 grados, con esta ayuda adicional de flujo de aire extra, bajó a 74 / 77 máximo con varias horas y a todo lo que da, en resumen si funciona, muy bien, y baja más de 10 grados conectándolo en su convertidor que trae a 12V, el convertidor es Molex, para 5v 7v y 12v para que puedas poner menos o más RPM. Lo recomiendo ampliamente! Sin dudas gran compra y muy económico para una solución térmica opcional a las liquidas que son costosas y complicadas de instalar. Esta opción no tiene ninguna complicación.

El artículo es muy bueno, tiene varias entradas de alimentación con la que puede varias el rpm de los ventiladores y con eso pude bajar a mi tarjeta de video 20 grados en uso normal pero no en uso rudo, es decir, que en uso rudo de la GPU no se mostró una diferencia instalándose en 12v .

Cheap but works well, fits in a pcie slot and does what its supposed to
