Dual 80mm USB Speed Control Fan, 5V Portable Cooling Fan for Flat-Screen TV Receiver Router DVR PlayStation Xbox Computer Cabinet Cooler

Bought this to introduce fresh air, and vent air from my paludarium thingamabob. Fixed my condensation issue with the higher humidity on the doors. Have them on medium now with one pushing in and one exporting, and has helped stabilize the humidity and temperature, which were both a little higher and inconsistently fluctuating with my target range.Only had em a couple days, but so far, pretty pleased. Works great for my application.Very quiet, affordable, will see how long they last....

I have an Asus Wi-Fi 6 RT-AX88U router that works great, except when it doesn't. After trying many things, I decided that the periodic rebooting might be caused by operating temperatures. I changed the factory firmware for the AsusWRT Merlin so that I could expose the operating temperatures. On the surface, the temperatures didn't "seem" too high. The CPU temperature was running in the 60's Celsius range for temperatures, and the 2.4 and 5.0 Ghz bands were running in the 40's and 50's respectively. Doing some research, I read others having stability issues clear up by introducing a dedicated cooling fan.I purchased this product and immediately noticed a reduction in overall operating temperatures for the device and over the course of the next few weeks, the stability of the unit improved drastically. As of this review, the current temperature readings are:Legend: 2.4 GHz - 5 GHz - CPUCurrent Temperatures: 37 °C - 43 °C - 50 °CThe CPU temperature is running at least 12 degrees cooler than before. I had observed previous peak CPU temperature as high as 67 °C. Now, it never breaks out of the 50s. The Wi-Fi temperatures remain equally cooler than before.I am running this unit on the medium speed setting, and I cannot hear it in the room running. When at high speed, I could hear it a little bit. For my installation, I have one fan running on the top of the router pulling air through, and the second fan underneath pushing air into the unit.In short, I strongly recommend this product if you have a need to add, or supplement cooling, to reduce operating temperatures. If it is for your router, networking gear, or an entertainment enclosure, this device will fit the bill as a quiet and effective solution. I have the fans powered by a dedicated USB power source, rather than being plugged into the router itself.

Works perfect for my needs. I use it to dry out my ski boots and scuba booties.Only improvement would be increased airflow.

These are multi purpose USB fans withe three speed settings. While they are designed more for cooling a cabinet that has music/video players inside, they also function as added cooling for your computer tower.Nowadays computers can get pretty toasty with the high wattage GPUs, so I decided to slide these fans into my case to help get even more air flow through the case. I put them in a position to pull more cool air inside and if I'm playing a fairly intensive game these little fans have helped drop the temps 10-15c at peak hot spot temps.The fans have a single controller and single USB power plug, so it's easy to attach it to your system. With a simple flick of my finger I can turn the fans on to low/medium/high, I typically keep in on medium but even on high they are not that audible when inside the case. They also have rubber feet so they stay in place nicely.It's far cheaper and easier that installing additional fans in a case, plus these having the added bonus of being able to be used elsewhere if need be. So far I'm happy with the purchase and hopefully they last a while.I'll update this review if I run into any problems down the line.

Worked great right out if the box. Using to cool a fan less Lenovo iot firewall, dropped cpu temps already by 10°C. Will buy again if needed.

I made a little box that holds them to use as a phone cooler while charging. Turns out they sell a version with the two fans connected together...These fans run quiet on low, medium and high make a little noise. USB power is very convenient.The only issue I have with them is that the rubber feet are too short. Setting them flat on the pads greatly reduces air flow. They work better if they are raised up an inch or two from the surface. You may want to look for longer screws or make a riser to give better air flow.

Put these against modem and router to suck heat away from them so they operate cooler

They're fine, pretty quiet as long as you keep them medium setting or below. No reason not to buy them, it's a good value.

Hace más ruido mi otra PC con sus ventiladores a full, estos no hacen mucho ruido al máximo y bajaron las temperaturas unos 20°.Al ser SFF, en reposo daba unos 50° la GPU, y ahora no pasa de los 34°.En full carga al 100%, daba temperaturas de 92° incluso más, por eso tenía que limitar los FPS y la resolución para que no pase de 85°.Ahora con estos a full potencia no supera los 78°, obviamente si lo pongo a como lo ponía antes limitando FPS y resolución, no supera los 68°, los recomiendo totalmente para una PC de bajo perfil.

I am using these fans to circulate air through a cabinet that is displaying some cold temperatures and high humidity. They are quite quiet, even on high speed. With the cabinet door closed, they are hardly noticeable. They are functioning well so far. I hope that the situation is a cold weather issue only and that I can run the fans periodically when required. I don't see the need to run them 24/7. GordK

Están increíbles estos ventiladores, son muy pero muy silenciosos, compre el dual y mantienen mi receptor Onkyo a una buena temperatura, valen mucho la pena, estoy completamente satisfecho con esta compra

My internet connection has stability issue, after a few days of puzzling I found the wifi router is quite "warm" and rebooting it kind of recover the stability issue, however the problem just not go a way.So it is time to "fan" the router, I was looking for fan that are quiet and power by USB, this set of 2 80mm fan with speed switch fit the bill, the fans also have nice rubber boot and shield already installed so it is just plug and play for my router setup.Since I installed the fans, no more internet issue, I put the speed switch to Low.One thing I kind of want to mention is there is a single switch to control the 2 fans.If you have similar issue like me with the internet, just ping 1.1.1.1 and look if ping sometime fails.By the way my router is Linksys WRT1900AC, I just lay the fans on top of the router and make sure the fans is pulling the heat away from the router, usually there is an arrow to indicated the direction of the flow, strangely I could not find such, just put the fans on High to figure out.Overall, good set of fans.

It comes with two fans and both are connected to a switch, which in turn connect to a USB A connector for power. A charger, not included, with 5V USB A output power these fans. I use it to lower the temperature of a router. Just leave the two fans on top of the router and set to "L" mode on the fan switch. The temperature of the router lowered by 20 C, which is very good. Noise level is very low at "L" mode, haven't try the other two modes; so don't ask. Note: the router is sitting on a dish stand and its bottom is not blocked so airflow from router's bottom to top is excellent.
