can I cool a router?
I have an older Rogers Coda router that gets very hot when it's running, and I'm considering switching to a new one. I'm curious if it's possible to manage the heat by adding a fan or cooling solution. Also, are routers capable of throttling performance, and can an old router function as a network switch?
You're moving too fast, not quite understanding the performance limits of the new router yet. Of course, a small USB fan can help keep things cool if needed—most routers have a USB port, so that's a practical option. It might handle itself without extra cooling, though some models struggle and crash frequently. The main issue usually comes from outdated firmware. Try turning off DHCP-server and firewall/NAT functions, then assign it a different IP address than your primary router. That should resolve the problem.
If performance issues arise or the device overheats, adding an external USB fan can help. I switched from a TP Link archer VR600 to an Archer VR2800, which would overheat under heavy online gaming. I used a Corsair 120mm case fan, cut the cable, and connected it via USB. It slowed down slightly on 5v power but worked. The router stayed smooth until it failed a few months ago.
I upgraded my WRT3200ACM with an advanced cooling solution featuring a quiet 120mm Noctua fan. It connects via USB to a PWM adapter, running at a reduced speed due to the 12V source and limited 5V output. On OpenWRT 19.07, this model was prone to overheating—often hitting 90°C or more—but now stays around 67°C with active cooling. The fan helps push airflow, and it’s currently delivering strong cooling when needed. The setup is placed discreetly under my gaming table in a corner.
I don't have access to your device details. I can't determine its compatibility. If the firmware is intact, it might function properly.
