2 TopicsNighthawk M1 custom fan
Hi everyone. Just wanted to share a little fun setup I made out of boredom. I found a spare slide switch and a 5V fan in my electronics box and also a 2 AA batteries socket connected in serial. I soldered it together and insulated the wires in a coating and stuck it beneath an opening in the lid and positioned the small fan inside the square, where the Li-Ion battery was supposed to sit before I detached it. It now runs on 3 volts providing a refreshing stream of air to aid the logic board in receiving its heavy loads from the telecommunications network. :) You could actually make it spin faster by using three or maybe four AA batteries without burning out the circuitry (I have tested it with as high a 12V battery, and it did tolerate that for several minutes). You could even get a 9V battery and a just slightly larger fan, or you could perhaps use a tiny lithium polymer battery and make a compact solution completely inside the device itself by using up the dimensions from the hollow battery compartment! I have noticed that the modem gets really hot when you pull torrents down for hours and some report that the DC current will decrease in case of overheating and start to drain the internal battery down to zero, while others report that using a fast charger (2.4A and up) without internal battery will less likely make their modem reboot, so for those people, this could be an adequate option to avoid removing or poking holes in the cover lid and mounting a regular sized cooling fan.
