ELUTENG Dual USB Computer Cooling Fan High Speed 120mm Fan Adjustable 5V USB Port Heatsink Cooling Fan 12cm for Laptop Receiver DVR PlayStation Xbox Desk Computer Cabinet Cooling

Works well. Really quiet....so quiet, I've actually left them on overnight (mistakenly), because even though I turned off any / all noise makers in the room (ie: computer, tv, etc.), I didn't even really notice the barely noticeable "hum" of the fans (they're that quiet). Turns my warm (almost hot) External HDD's almost room temperature (when I touch the running HDD, I can't tell from the temperature of the casing that it's running...only from the movement of the platter / arm). Like the fact that it has "Feet", on the corners, on both sides, so that you can not only elevate the HDD off the desk allowing more HDD case surface area for heat dissipation, you can either BLOW air onto the HDD, or SUCK air away from the HDD (depending on your needs)...just turn the unit over, depending on which way you need the fans to go.

I use this under my DJ controller in its case to keep it cool. Does the job. Not too noisy. So easy to install and mount just plug it into any usb port. Moves air very well so it has sufficient power. This fans rarely fail so I see it will have a good lifespan.

I bought the 80mm version to add extra cooling to COB lights like my Godox units, and they’ve been great for that. I zip-tie the fans right to the body of the light and it noticeably improves airflow, especially during longer sessions when heat usually builds up. It’s quiet enough that I don’t notice it running, even on the higher setting, and the USB power makes it easy to plug into whatever power source I already have nearby. Build quality feels fine for the price and I’ve had zero issues so far. Simple product, does exactly what I needed it to do, no complaints at all.

Good little fans, low noise and moves air pretty well. For me, I separated the 2 fans to cool my NVR on 1 rack shelf and a PC on another rack shelf. Keeps the NVR and PC nice and cool. I also like that the fans run off 5v USB-A plug so I don't have to run them to 110v AC plug, I plug them into the PC USB port, done!

Purchased this fan for the sole purpose of cooling my PS5 inside an entertainment cabinet. Easily plugs in the back USB port of a PS5 so it turns on with the console. I have it on low speed and it moves plenty of air keeping the cabinet space cooler than without a fan. There isn’t any noise from the fan while in operation on low speed and the slightest hum when switched to high speed. In any case if you’re playing a game or watching a dvd on the console, you won’t hear it.

I only just took this out of the packaging and put it directly into use as cooling fans for our home router. I read all the reviews about these being noisy, and perhaps there were some that fit that description. However, the ones I got were super quiet! Seems to be a great value for the money. It moves heat away from my router and the fit was perfect. The three position speed switch works fine and I run the fan on high constantly. I'll update if the durability isn't good. I expect at least a year or more of service.

Purchased this usb dual fan set to ventilate my PC cabinet. Pretty awesome. Very quiet. I was very impressed.

Works out of the box and can choose different fan speeds over USB depending on the situation. Pretty useful and flexible too as you can connect over USB which is widespread. The fan grille is a plus so your fingers don't get chopped off by the 140mm blades and you can position it on your desk/beside your computer with ease.
