2X 120mm Computer Fan with AC Plug, AC 110V 120V 220V 240V Variable Speed Fan for Mining Machine Cabinet Chassis Server Workstation Cooling

This works great for the price. It's cheap fan but does a good job. I installed it in my TV stand cabinet where my ps5 is so I can run the ps5 with the doors closed. This sucks out the hot air keeping it cool inside a in closed area. A home project that worked out. Would buy again. May try to find a quieter fan.

I mounted this device on the inside of the return air register screen. Rather than boosting the cool air up from a floor register, I "extract" the warmest air near the ceiling. Closing the door to the room creates a little negative pressure which draws some extra cool air from the floor register and exhausts the warmest air in the room into the return. Would be better to have a dual-zone system but with an older home, this is not easily done. This dual fan does the job quite well. I also appreciate the speed control which allows the quietest operation when the air conditioner can handle the load and higher speeds when needed. A quality product. Several extra parts were provided to assist with different applications.

So I am not using these for the intended purpose I am using them to fix the airflow on an under desk treadmill. For that purpose they work great. They move plenty of air and the speed control is nice. Build quality is fine. Again I am using them for a niche use case so take from this what you will.

Works great, help to keep cooling my lap top.

Works awesome for cooling my broadcasting equipment

Works perfectly for cooling electrical cabinets from either normal heat build up or from generated heat from VFDs, transformers, miners, etc...

The cabinet ventilation fan with variable speed, variable voltage input, and dampers is an excellent product that is perfect for keeping electronics cabinets cool and boosting central air systems. This fan is specifically designed for use in cabinets and can be customized to meet your unique needs.One of the standout features of this fan is its variable speed and variable voltage input. This means that you can adjust the speed and voltage of the fan to suit your needs, allowing for greater control and energy efficiency. The fan also comes with dampers, which allows you to regulate the airflow within the cabinet, ensuring that the temperature is maintained at a consistent level.The installation process of this fan is straightforward, and it can be mounted either horizontally or vertically, depending on your needs. Once installed, it is virtually silent and does not create any vibrations that could potentially damage your electronics.Using this fan to keep your electronics cabinets cool is an excellent way to extend the life of your equipment. Electronic devices generate a lot of heat, and if not properly ventilated, this heat can cause damage or even failure. With this cabinet ventilation fan, you can ensure that your electronics are kept cool and protected, allowing them to operate at optimal performance.In addition to keeping electronics cabinets cool, this fan can also be used to boost central air systems. By installing the fan in a duct, you can increase the airflow and circulation of your central air system, which can help to reduce energy costs and improve overall comfort.Overall, the cabinet ventilation fan with variable speed, variable voltage input, and dampers is an excellent product that is versatile, efficient, and easy to install. Its ability to regulate airflow and temperature makes it an essential addition to any electronics cabinet or central air system. I highly recommend this product to anyone looking to protect their electronics or improve their air circulation.

To be clear upfront, I'm not really using this pair of fans for their intended purpose, for cooling an entertainment center or something like that.I used them to make a a soldering fume extractor. Previous fans I had used did not move enough air, and when a filter was placed in front, they moved almost no air at all.These things REALLY have some power when turned up all the way on the handy little control box. I put a carbon filter in front to absorb most of the solder smoke and it still moves a lot of air, even with the filter constraining it.The fans seem to be of decent quality. The brackets holding them together are nicely made and work well. The little wall adapter power supply box works well. I have not tested yet if it is well filtered to prevent RF noise, that remains to be seen.As far as regular noise, at full power it is quite loud. But that's not terribly surprising considering how fast they are turning! It doesn't bother me but it may bother some.Overall, good product!
