ELUTENG Mini 40mm 5V USB Fan Desk PC Fans with L/M/H 3 Adjustable Speed Portable USB Computer Fan Case Box Electronic Cooling Fan 5300 RPM with Metal Grill for Laptop/TV Box/AV Cabinet/PS4/PS5/Router

Nice little fan, it has 4 speeds, quiet powerful for it's size, used to cool ps, no loud either, even on full speed, not a bad price, USB plug in. Delivery was good.

I am using this to help cool a Linear Power Supply. Rather than the fan extract the heat more rapidly I removed the grill and turned it upside down to blow cool air into the power supply. Even on the low setting it has performed exactly as I needed it to. I didn’t want to freeze the LPS just bring the heat down a few degrees. The 40mm size is perfect for the Sengterbelle 12v LPS leaving enough venting either side of the fan for the air to escape.I would like to know how long I can leave this fan on for but there is no info on a constant run so it looks like trial and error but in the meantime the heat is under control even without going high on the setting, works just fine on low. Some say this fan is noisy but seriously I am not sure what they maybe using it for but I have had louder mosquitoes in my ears than this fan! It’s quiet.

Sounds a little like a PS2 starting up at high but does the jobDoesn't push the most air but does the job, good to keep my laptop cooler and less noisy when gaming or using ai.Seems like it could be good for circulating air in a TV unit with modern consoles or PC also

This is a good little fan that does exactly what you'd expect, but I found it to be noisier than I expected. It is good to have different modes and speeds/speeds so I can lower the noise when running at low speeds. I would recommend it, but I would like it to be quieter.

Bought a couple of these now great for cooling down my router as it’s placed In a cupboard. Low noise, low power consumption doesn’t look too outrageous.

This USB fan has been a lifesaver for my old PC — it helped prevent it from overheating and keeps it running smoothly. After I started using it, my stepbrother even took it over because it works so well, and it’s still going strong! One thing I really like is that it doesn’t wiggle around or vibrate too much, so it feels sturdy and stable even when running.Installation was super easy — I just plugged it in, and it was good to go with no hassle. It’s also got a sleek, clean design that fits nicely with my setup without looking bulky or out of place. Overall, this USB fan is reliable, effective, and looks good doing its job. Definitely recommend if you need a simple cooling solution!

Needed a fan to help airflow on my work laptop. This easily fits under my laptop stand and helps with airflow, but it’s a bit noisy…

I purchased this fan to replace a DIY job I carried out on my TV cabinet.My PS4 Pro is in a wooden TV cabinet with very little ventilation and the back of the cabinet would become noticeably warm when playing games, definitely not a good thing!To remedy this I cut out a square hole from the plywood back and fitted a PC fan that I soldered to a male USB connector (not ideal but it worked) to draw air from the back of the PS4 and out. While this certainly worked, I didn't feel too happy leaving such a botch fan connected to my expensive PS4 in case the worst happened.After some research I came across this product and despite it seeming a little costly for what is essentially something I created using bits I had lying around, I thought it would be worth trying.It arrived in a simple no-fuss box and I soon had it installed and set up.The key thing here is that the fan is rated for a 5V power supply unlike most PC fans (12V) so this runs nicely off the PS4's USB port and it moves a LOT of air compared to my DIY version. The metal grille ensures wires won't get caught up in the fan and it also gives a very high quality finish to the product.I opted for the variant with speed control so that I could turn things up only when needed.The fan cannot be heard over the TV and I am extremely happy with the product!
