Wathai 120mm x 25mm 5V USB Cooling Fan
A whisper-quiet USB fan for basic cooling of routers, consoles, and low-power electronics.
Wathai’s 120mm USB fan solves a specific, common problem: silent electronics that run too hot. It’s a simple, plug-and-play cooling module for the countless gadgets that lack active airflow.
At 5V USB power, it draws minimal energy from any port, making it ideal for set-top boxes, routers, or network enclosures that get tucked away. The 120mm by 25mm frame moves a decent volume of air quietly. You won’t hear it over room noise. In practice, this can mean the difference between a stuttering streaming device or a consistently stable connection from your gateway.
Just know its purpose. This is a supplemental fan, not a replacement for high-performance PC cooling. The build is functional and the included rubber mounts help with vibration. For a few dollars, it’s a pragmatic fix for overheating hardware.
