ANVISION2-Pack 40mm x 10mm DC 12V Brushless Cooling Fan, Dual Ball Bearing, YDM4010B12

Used for the intake on an Xbox Series S. Paired with a usb hub. Surprisingly quite perfect size and good air volume. No complaints.

I ordered these for my son who has an old security camera system (10 year old Swann), and the little fan in the system was getting noisy. He swapped it out with this new one and he was very happy with how easy the swap went and how much air the little fan moved.

Purchased to replace ortur laser master 2 laser fan and they are thinner than the original fan.

came quickly and for being small they work .

I wanted to add a cooling fan to my Reolink NVR camera system. Fan fit the factory fan location perfectly, The fan case has hex shaped indentures for nuts and that size would me M3 you'll need M3x15 screws at minimum for attached to a stamped metal case. I chose to use nylon lock nuts with in so vibration was not a concern. The connector on the fan was an exact fit for the Reolink board socket.

These fans are LOUD. I installed this on my Ender 3 Pro hotend and it is significantly louder than the stock fan. However, if you are dealing with heat-creep issues like I was, these fans are very powerful and are really good for regulating the heat break temperature, I haven't had any clogging issues since, but I am just not a fan of how loud they are.

One of the out of the box issues with using the Raspberry Pi is the fan staying on even when the Pi is safely "shutdown". Since most fans are connected to the 5v gpio pin, power will continue to run the fan and there no way control it from those pins. One option is to use a moffet pcb to cut off power to it without damaging the fan but then you may require soldering which can problematic for some folks.The other option is to use a NPN transistor to control the fan from another gpio directly. This is actually a good way to handle it as you can code how you want the fan to function, when to activate it based on powering on the Pi or even based on the current temperature. But, you'll have to properly wire the transitor and do some coding and that maybe scary for some folks too.The easiest way to handle the fan is of course, by using a USB fan. Basically, if the Pi is on, power is sent to the USB port to turn the fan on. If the Pi is off, power is turned off from the USB port thus turning off the fan. No coding, soldering, or transistors needed. Granted you will have to give up a USB port but totally worth it for me.I'm using this fan for a game console rebuild and it's perfect for what I need. Runs quiet and keeps the Pi cool at 45 degrees consistently. Definitely recommend this one for anyone doing Raspberry Pi projects.

I had a 1TB USB hard drive fail that I used to play video, installed in a fixed location that the drive slid into and was powered on 24/7. I noticed the drive was hot when I removed it as well as the USB switch powering it. So I conjectured that it may have been the heat that caused the drive to fail prematurely. So I got the Anvision fan to blow air over the fixed installation and choose it becuase "Quiet" was used in the description. I simply added double side tape to one side of the fan and placed it so it would blow air over the drives and pull air over the USB switch used to power the drives. Just the little bit of air it moves made a big difference and the drive and the USB switch were cool to the touch after several hours of operation. As far as noise, sitting 10ft away I can barely hear the fan and after a while its not noticeable at all and is especially not noticed when playing the TV. Outside noise, refrigerator are much louder then the fan. If noise was a problem I would get a fan with adjustable speed but this one seems fine for me.
