Ventilador de refrigeración con router USB de 4.724 in x 2

Works great! I was pleasantly surprised by how effective it is at cooling my system, and it's not nearly as loud as I expected, even at higher speeds. The variable speed controller is a nice touch, letting me adjust the airflow to fit my needs. Overall, it’s a solid fan that provides excellent cooling without being overly noisy—definitely a great addition to my setup!

I couldn’t be happier with the WDERAIR 240mm USB Powered Fan! I bought it to help keep my car amp cool, and it’s done an outstanding job. The fan is easy to install and surprisingly powerful, providing excellent airflow to prevent overheating during long drives.One of the best features is the variable speed controller, which allows me to adjust the fan speed based on my needs. It’s quiet enough at lower speeds not to be distracting, but when I crank it up, it moves a serious amount of air. The USB power is super convenient—I plugged it right into my car's USB port, and it’s been running perfectly ever since.This fan has made a noticeable difference in the performance and longevity of my amp, and I’m confident it will work just as well for other electronics too. It’s a versatile …

✅ Cools my almost 8 year old Xbox360✅ Quiet✅ Don't need to use another outlet, plugs right into system

the controller cord doesn't work. Plugging in directly works fine but I cannot change the fan speed without the controller cord.

We have a lot of the single fan solutions that use this approach. Allowing us to use them for various projects where we don't have the luxury of manually running wires. Being able to tap into any USB port is a luxury as you're off and running with it in no time.In this case, having the double fan design is absolutely fantastic. I chose this one for a very specific reason. For placing it next to an external cloning device for hard drives. With the idea that this will help increase air flow around the drives as they are cloning. Reducing heat, and minimizing any chance of failure. The double fan design knocked the job out of the park with great success.They can easily see somebody designing this into a cabinet or entertainment center to help pull heat out. Especially since you likely have …

I hope this doesn't sound bizarre but I got this for our countertop ice maker. we have one of those pellet ice makers and on the really hot days, the ice maker's internal fan sometimes has issues keeping up so I got this fan to use as an assist to keep the motor from overheating. It works perfectly. I just stuck it on with some tape to the vent area and the fan really helps the motor from straining when the ambient temp of the room becomes too high for the ice maker. I know it is a weird application but I love ice and I love my pellet ice especially so whatever it takes. If you know, you know.

I ordered this Wderair 120mm 240mm Computer Pc Case 5V USB Powered Fan with Variable Speed Controller to replace two 120mm fans that I am using to cool some external disc drives.As a fairly prolific photographer, I am constantly adding more disc storage. I'm now up to a set of 4 12TB external drives. I noticed that I'd typically get a heat alert from CrystalDiskInfo after a few hours of working. So, I got a couple of computer fans that each sit atop a pair of the drives. One of the fans came with a speed controller, but the second one runs at full speed all the time. Honestly, the noise level was intense and I found that it was interfering with my concentration while editing photos.This unit combines two 120mm fans. They are held side by side, and the unit fits nicely on top of my 4 …

I am using this to cool an standalone external hard drive, 20TB that can get pretty hot while backing up from my NAS drives. This dissipates the heat nicely, pulls cool air in from below and blows it upwards which is great for cooling the drive during max read/write speeds. It is USB powered, and the platforms are sandwiched on two 120mm fans, so if you ever needed to replace them, with some minimal wiring and soldering you could keep this going for quite a while. It has padded rubber foam feet that are very sturdy and keep vibration noise down to a minimum; 3 speeds on the fan (High, Medium, Low, Off-in that order); and a nice solid frame that will keep fingers from getting sliced and remaining very strong for the weight of what it may hold. A great product!
