Forced Air Cooling of WiFi Amplifier - DECOMMISSIONED.

I recently installed an 8 watt wifi amplifier in my home. Measuring the power used showed 2.4 watt. I'm Guessing the output power is approximately 2 watt. Really bad labelling from the manufacturer of this amplifier.

I Have made sure to change my router's frequency channel to make sure there is no interference with my neighbors.

After a solid day of operation I have been very pleased with the 700 foot radius of connection I enjoy now even though houses and other rf obstacles. I did a thermal imaging scan of the amplifier and it had hotshots of over 63 Celsius! That's too hot! Read on for my solution to this issue.

Remove the Bottom Plate and Solder 12volt Fan.

I used an Allen key to take out the back plate. I soldered a 12volt blower fan to the circuit board and simply pushed the fan into the housing carefully.

Power Up and Enjoy.

It is true without the bottom plate that the amplifier will pick up more noise but I prefer a cool amp over a less noisy one!

After 9 hours running the amplifier is at room temperature and working great! I attached a thermal image of the amplifier running continuously for 4 days. Max temperature is 36 Celsius internally.

Also the range is still awesome and I have no issues with noise so far.
