GDSTIME 3 x 120mm Rack Fan 220V 230V 240V Computer Cooling Fan 4V to 12V Adjustable Speed Controller with AC Plug Dual Ball Bearing 120mm x 38mm For Server Cabinet Chassis Machine Ventilation

The media could not be loaded.  At the moment my son and I are building up a server cabinet chassis, this is going to be fitted with Intel Xeon processors and a fairly large amount of storage. We were looking for fans to keep internals of the cabinet well ventilated, this GDSTIME high airflow 3 fan system came up for review and I was sure that somehow, I would be able to fit this on the back of the chassis.Before fitting I gave the fans a quick test, and I was impressed with amount of air a 3-fan system can shift. Each fan has a specified air flow of 116 CFM which is about right for this size of fan. As it is noisy on the fastest fan setting, I think I will set it at about a third to half way on the potentiometer. The potentiometer varies the voltage between 4V and 12V, maybe at some later stage I will be able to control this thermostatically with a different controller.Build quality seems to be good, and hopefully the fans dual ball bearings will keep this running noise and rattle free, for the 50000 hours quoted life span.Overall, this high airflow 3 fan system should be a good addition to any electronic equipment that needs good ventilation and cooling.I hope you find my review helpful

I got this GDSTIME 220V 240V Powered High Airflow 3 x 120mm AC Axial fan for my server rack as I needed some manually controllable airflow for winter and summer temps. After fitting and installing these new fans, I am now able to accurately adjust the airflow using the dial controller on the adapter. The fans are quite powerful, providing a high and reliable airflow. Along with a good rpm, it cools just as expected and the fans are pretty silent as well. The fans are also protected by metal grills which also keep out fingers, cables and such as to avoid human injury, or damage to the fans. These fans have a unique design in which they are connected by a very solid custom metal buckle and screws. It's a fantastic, professional-like high quality and I surely recommend.
