Is it safe to install ventilation holes on the ZTE F50 router?
Hi everyone, I'm working on enhancing the thermal efficiency of my ZTE F50 router. It has a completely sealed plastic casing with no vents, and it operates continuously for 5G data, which means it often becomes quite hot.
I’m considering drilling a few ventilation openings and installing a small 80 mm fan at the top to release the warm air. But I’m worried about safety—might this affect the internal antennas or other delicate components near the case walls?
Should I drill on the top or bottom side? Also, are there any general guidelines for adding vents to sealed networking equipment to prevent damage?
Any advice or experience with similar projects would be greatly appreciated. Thanks!
I own a mediocre ZTE modem that comes with an ISP, which causes it to restart repeatedly when it overheats. I removed the plastic casing and installed an old Pentium cooler on top of the main IC, securing it with thermal glue so it stays in place permanently. You can drill holes, but be careful not to damage the board.
My unit sits on a wooden shelf and I rarely handle it, so any risk of further harm is minimal. It's also an older DSL model without antennas or other concerns. The fan is powered from the same supply, and I connected the wires to nearby contacts on the jack.
Treat it like a CPU: the fan should blow air in, ensuring heat reaches the chips. You can also make small slits on the sides for better airflow. No need for a high-speed fan.
Additionally, adding a foam filter at the top would help prevent dust buildup over time.
Did you really change the router according to the video? Can you share some pictures of your ZTE F50 router setup and connection?

Extra cooling probably won't make a difference. More details are needed.
