If your Raspberry Pi is getting a bit too warm, this little 5V cooling fan is a cheap and easy fix. It’s super small, plugs right into the GPIO pins, and does a solid job of keeping things cool, especially during heavy use like gaming, or a 24/7 server (like pihole). It’s not totally silent, but the noise is barely noticeable unless you're really close. Installation is straightforward, and it fits nicely in most standard Pi cases. it’s a simple, low-cost upgrade that helps your Pi stay cool and run smoothly. Definitely worth picking up if your Pi tends to overheat.
