ANVISION 2-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.

came quickly and for being small they work .

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

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.

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.

These fans are well made, high volume of air flow for a small fan. Noise is not a problem.

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.
