If you're concerned about it, you can arrange a cooling fan
next to the item.
I have a couple external fans now. One points at my rack
of AC wall wart power adapters. A second cooling fan points
at my ADSL modem (draws perhaps 10 watts). The wall warts
shouldn't need cooling, but I added it as a debugging step
when I started having problems. On the ADSL modem, it was
a suggestion based on failures in the caps inside that model.
I added the fan to see if the thing would last longer.
You can buy 12V adapters at an electronics store, buy a computer
case cooling fan, then wire them together.

When using stuff like that, it's up to you to figure out which
wire is (+) and which wire is (-). [Use a multimeter...]
On a two wire fan, red is the (+) one and black is the (-) one.
Connect (+) to (+) etc.
You can cut the Molex off of one of these, then twist together
the load to the source. http://www.radioshack.com/product/in...ductId=2262091
To make a stand for the fan, buy some 3" bolts and nuts. By putting
the bolts through two of the fan holes, you can make a stand for the fan
to keep it upright. Placing a piece of rubber underneath the thing,
will also reduce the coupling of fan motor hum into the desk.
The fan can still get tipped over of course. My scheme isn't bulletproof.
To cover where the wires get twisted together, you can use heat
shrink (polyolefin) tubing. Cut off a 1" length, fish it over
the wire on one item, before twisting the wires together. Slide
the tubing over the wire to cover it. Apply gentle heat (that's the
hard part, too much heat and you'll burn it). Heat shrink, if done
well, can be a bit more reliable protection than electrical tape.
In warm weather, electrical tape becomes gummy. The mistake
I make all the time, is selecting a too slim piece of tubing.
It has to be a bit larger than the thing you're covering, or
it won't easily slide over top of it. http://www.radioshack.com/product/in...ductId=2102875
You can connect more than one fan (in parallel) to the adapter.
If a fan draws 350mA and you bought a 1 amp adapter, you
could connect two fans to it (twist the three (+) together etc).
