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

Ps4 no longer sounds like a jet engine taking flight, it really is very quiet and even running heavier games it's made quite the impact in keeping the system cool! I could almost see if you wanted a super quiet fan for your desk this would probably be just as great, it's that quiet and effective.

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.

As for the size, it fits my laptop perfectly, and the pads keep it from sliding around which was a concern at first, but it's definitely not going anywhere! The fans themselves run off of a USB cable, with a slider switch from off>low>medium>high and barely make any noise at all. In fact, my own laptop's fans are louder. These things are BEEFY by the way, i use a pretty low-quality, unmaintained ROG Asus gaming laptop with a 1060 that usually heats to 91C. This thing bumps it down, at 70%-90% load, straight to between 68C and 87C. That's a pretty big improvement, if you ask me. Also the plug being USB is pretty useful. I put it under my laptop but honestly this thing looks pretty versatile, you could probably use it for other stuff too if you want. Very good cooling fans, would definitely recommend if your laptop overheats and slows down.

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.

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

Give it some time to get hot (couple hours of running) Because they will make noise in the beginning. I really hope they can make the controller feel a little bit more premium, it’s very fragile and cheap feeling. Would also like to have add ons, tubes, intakes etc. Maby rgb led lights also. Works great for my hometheather amp 👍

Hooks up to my USB port in the back of my vehicle. Low, medium and high settings all put out a really good breeze! Extremely quiet and super lightweight. Has been pretty reliable so far to help keep my dog cool while traveling and waiting at events. For a Ruffland kennel fan I recommend this and it’s affordable!!

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.

My External WD drives were idling around 57°C and of course ran even hotter under load. This fan on the low setting has brought them to 37°C! Plus, it can run off a USB hub. I can't speak to the longevity, but it feels solid.

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

I am 100% happy with the product. However, I think I received a returned item, as the screws were out of the bag and the cable was poorly folded; though there is no issue with the product itself, one would expect a discount. as stuff like that isn't generally resold at the same price. Anyways, on to the product. I have 6x 18-22TB Western Digital External hard drives, and these run warm at idle 51c, which isn't bad, but they were pushing 57 at intermittent load. Anything below 60c is safe, but I don't want to lose what I have, so if cooling them buys them a few more years, I'll do it. It took about 10-15min to start cooling down, but now, at idle, it is 30c and 35c at load, a 21c drop in temp in a warm room. I have the hard drive on top of the fan blowing up as there are vents on the external, top, bottom, and back, so it is a perfect solution. I will buy more for the rest of my drives once I set up my rack.
