ELUTENG Dual 120mm USB Fan with 3 Speeds 5V Ventilator Fan Portable Cooling Fan

There is no warmth associated with these fans. They are quiet and move a considerable amount of air behind out QLED TV. The TV is in a cabinet and heat is a factor. These fans solved that issue for us. They plug into a USB port on the TV and turn on and off with the TV. Definitely recommend.

EXCELLENT

Very quiet in operation. They are being used to cool two external hard drives. Crystal Disc reports excellent cooling. Very surprised at the low noise level. On low they are inaudible and adequate for my application.

Keeps Receiver nice and cool

They are quiet but not strong even on the highest setting.

I have a couple of pairs of these fans, as well as a 80mm sized pair, for cooling electronics. One pair of these 120mm fans is on my Yamaha receiver, the other pair is suspended behind my 32 inch OLD Sony LCD screen Bravia. The 80mm fans are behind my PS4, Switch, and Wii U. On the rare occasions I fire up the XBox One, I just move the 80mm fans up a shelf to where the XBone is. I don't know the exact numbers for these fans with regards to air volume they move, but it seems to me that the smaller fans force more air, but obviously they don't cover as much surface area. The fans don't help my TV much, which I expected. They cool my receiver more than I expected, and I think the 80mm fans are going to extend the lifetime of my PS4. That console runs really hot, especially at the power supply, and the 80mm fans help cool that very noticeably. Oh, and the fans are quiet enough that I sometimes forget to unplug them and have slept peacefully though the night with them running. Although it is summer here so I always have a large fan running anyway..... Anyway, I recommend the 120mm fans for receivers and the 80mm fans for video game consoles. Maybe I'll try some 40mm fans later....

Cold air keeps my desk units cool. It’s so cold I’m impressed. Looks like a normal fan. Amazing value. Little short cable length but gets the job done. Fans are large full 4 inches. Keeps cpu cool and safe. Protect your investment.

Bought this to run constantly to keep a chameleon enclosure with fresh moving air. 1 week later and its still working. Seems like it was built with better quality compared to another set of small fans i had that lasted 2 or 3 weeks. Time will tell.

Low noise . 3 speeds that seem to actually be different. Seem well built and are fairly powerful.

ボタデンの充電時のファン吸気と排気の所に付けて使用 ファンの回転も3段階あるし気になる音も無く良かった

二つの送風機を一つのスィチにより入り切りができる。

I bought these fans to add airflow through my chameleon's mesh terrarium, they work well and are very quiet, I just wish they moved a little more air than they do. In any case, they definitely do the job I bought them for, so 4/5 from me!

Works well and is quiet
