ELUTENG Dual AC USB Computer Fan 140mm USB Fans for Cooling 3 Speed Control 12V Computer Fan with AC Plug 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 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.

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.

So, I clearly wasn't paying attention when I purchased this, I wanted to get mini fans with a control for a little terrarium so I could circulate some air into the setup, this is a heatsink. At first one fan didn't work, it was due to the grill, when I loosened it the fan worked again. I decided to experiment with this mini heat sink and found that it is surpringly effective at looking phones while charging, even with screen down on the heatsink (if the phone has a case). So now I have a little charging stand with this cooler, it will wick the heat off a hot phone almost immedietly. Hoping this will extend the life of the phone batteries in the long run. It's been wicking the heat off of any device I am charging. Yes it is loud at full power, but I usually havea headset on anyway.

Perfect size and zero noise! My AT&T DVR was running super hot so bought this little fan to try. Absolutely impressed, easily plugs into back of router for power and with fan set on low DVR is cool to the touch. Highly recommend 👌

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.

Works great for cooling down my modem.

Does what it says on the tin, runs quietly in my desk cubby cooling an AC receiver and laptop power supply. Not something I'd run inside a PC case, but perfectly functional for AV/Pre-amp/external power supply cooling. Time will tell how long it lasts.

Oh it's bigger then I expected wow it brought my drive disk temp down by 10° c so u can't complain just just on default speed. I can't complain Makes no sound no vibrations and a constant speed I am using its own USB dock and not a laptop or control bored USB. I haven't tested it's threw a ps4 port ps5 ECT..

Works as advertised, it's pretty quiet and is keeping my server cabinet much cooler than it was before installing this fan.

Use this to cool down my AVR and is work as advertised. There are 3 speeds settings and so far I use the lowest speed and it is still able to keep my AVR cool down after hours of use. Would recommend it to others.

Nice quality but a bit noisy a high speed despite this its good product

Excellent fans. I have a dual 120mm cooling my Receiver. And a dual 80mm cooling my Cable/PVR box
