that's a perfect way to start a fire or electrocute some poor slob. well, don't tell your home owner's insurance.
How were you going to power the fan in a consumer WiFi box anyway? If you're planning on leaving the PCB naked without the plastic. they die in no time and then either toast the whole thing or draw so much current that the power supply dies. and jeezus, for the love of god, don't put one of those crappy 2" fans anywhere near anything you care about. If you're worried about heat, better to sink the power regulators than anything else on the PCB. sometimes its power regulation on the board, but most of the time its in the wall wart. most of the time, the power supply dies when an electrolytic capacitor dies. most devices like these die because their power supply dies. Keep them cool, and they will last longer.Īctually, that absolutely not true. Most devices like these just die from thermal stress. Bonus points if it's a heatsink + fan that you can power. (in this instance the radio & CPU are the most important)Īpply some thermal epoxy and attach a heatsink from an old computer CPU. Remove the plastic case and expose the internal circuit board. As far as device longevity, you should do this to every consumer electronic device you own:
