Intro: Adsl Modem Cooling Fan Mod
In this hot summer days, your modem may be get crashed in cause of high temperatures. and high temperatures can make your modem work slower. just a small fan can make your modem cool enough. cause you just need to supply air circulation.
here's the things we'll need:
-a piece of soldering wire
-double-sided adheshive tape
-a computer fan of your choice
note: the fan should use the same voltage with the modem, and the modem+fan power(generally in mA unit) shouldn't exceed power adaptors power. example, my modem wants 800 mA, and fan needs 170 mA. my modems adaptor can give up to 1000mA realtime. this is okay.
-your modem, of course.
Step 1: Cutting the Fan Air Hole
in this step, you need to decide to where will you open the hole.
after this, heat your soldering iron, and open the hole. then fine edges with nail cutter.
Step 2: Installing the Double Side Tape to Mount the Fan
first, place a piece of tape under the fan(air out side).
thenshape it with cutting blade.
note: if you want to mount your fan with screws, you wont need this step.
Step 3: Mounting the Fan
remove the protect paper-film on the tape. then place it on the air hole. do not forget to take the power cables to the inside.
Step 4: Testing and Soldering the Power Wires
first, test you fan to solder it in right "current direction"(?). then solder it to power pins on your modem board.
Step 5: Reassemblying the Modem, and the Finish.
reassembly your modem. and start using it!
