ELUTENGUSB Fan 80mm 5V 2 in 1 with 3 Adjustable Speeds, Double Row USB Computer Fan 80mm PC Fan 8cm with 8 Shock Absorbent Feet for PS5 PS4/Laptop/TV Box/Router

I got these to help with temps on my wife's PS5. The PS5 lives in a cubby on the side of the tv unit. This causes a lack of airflow with all but one side being blocked off to moving air. I got these fans to help push air from behind the PS5 out the open end of the cubby.After the first few uses I could notice a difference in how hot the PS5 was getting, sadly this is only a feeling as I font have any temp sensors to monitor this. But from a touch feeling the ps5 feels cooler and it's not a loud.As for the 2 fans, I went with the 140's simply because bigger fans move more air while turning slower. Turning slower normally means less noise and this is can happily say is true. In my set up having them on the middle setting you can't hear the fans at all. Putting them on high brings them up to around the same volume as the fans on the PS5. So this is great news on a noise level for me. I will keep them on the middle setting unless in the summer we get some really hot days.In short does everything I could ask of them, low price, low noise level and perfect for keeping the air moving around the PS5

I bought this to actually sit under a SkyQ box and run to cool it down as well as give it space underneath for air to flow. It actually works quite well for this and uses a USB port on the Sky box itself for power.A second one I bought to help blow air into a computer case that was sitting inside a cabinet and had poor air flow.For the price I paid they were good value and work well enough for the job with variable speeds on the controller.

My few-years-old windows10 PC (all in one form desktop) has cooling fans going full pelt (and noisily) when I'm streaming anything 4K. The fan noise is irritating and also I worry if the graphics card will give up the ghost. I use this fan to add to the cooling. Placed under the desktop all in one pc by the ventilation holes, it perhaps helps a little as judged by the fan noise from the PC. When balanced on top of the all in one PC, by the exhaust vents (with this fan positioned to suck from the vent rather than blow into it), it helps more. But there's the risk of knocking off the fan balancing on top of the desktop, already happened once. The noise from this fan is much less than the PC's own cooling fans, so less annoying for me. Good that this fan can be powered from a USB socket on the PC. I was hoping the cooling from underneath the all in one desktop PC would do the trick but that way it's only of limited benefit.

I bought these fans to fit underneath my hifi amplifier which was running too hot during these summer months.The base, top and sides have numerous slots which were struggling to keep the top at an acceptable warm temperature.After testing the fans to workout direction of flow, I removed the upper cover and feet due to lack of space. I also placed an extra pair of rubber feet beneath the amp leaving a 3mm gap between the top of the fans and the base.The amp had been on for a few hours and the top was relatively hot.Within 5 minutes of running the fans on the slowest (and quietest setting) the top was warm, and 10 minutes after that it felt almost cool.I accept that the amp's components would no longer be at normal operating temperature (which is desired) but knowing that none of them were in danger of overheating outweighed that.The noise level is acceptable on the lowest setting. I can only hear it with the sound off.I turn the fans on when turning the amp on, and the top stays cool all day.I am completely satisfied with the product.

Purchased this for my AV receiver to keep it cool, all 3 settings work (L,M,H) with no noise coming from the fans. I also have the fans plugged in to a 4 way USB adapter so giving me future expansion should I need it. They are well made & kick out some decent air flow. Overall I'm very happy with these 😎

My mini-pc kept overheating and locking up. Since I've had this it's stopped the PC overheating. It's fairly small, runs at different speeds and controls the airflow. Works a treat for me.

The fans are nice and quiet, and the rubber dampeners work great, but the airflow isn't all that much to call home about... But it does help keep the air moving in my homelab, rather than stagnant hot air sitting around.

I got this to use as a radiator fan as way cheaper than a purpose built one, although you obviously need your own USB power supply and some sort of support to stand it on below the radiator. This does the job very well, I may get another one, I use with a smart plug.The build quality is excellent and it’s nice it has grills over both sides of the fans. It’s very quiet, unless on max speed, but it’s a small fan, so that’s to be expected.
