Won't hurt, though I think people obsess over the 105 degree (it's C, not F)
thing, if anything in a monitor is approaching 100C, something is wrong.
Obsess? No. Read the capacitor manufacturer's specifications: 1000
hours life at the rated temperature. If you chose a lower temperature
part it will work, but have a lot shorter operating life. How many
times do you want to repair something for the same problem? Would you
like to recap or replace a computer motherboard every couple months, to
a year? Also, as the ESR starts to rise, the electrolytics generate more
internal heat. Operating temperature is a complex issue. Ambient
temperature, airflow, dust buildup, component spacing all affect the
capacitors. Use low temp parts if you're cheap, but use better parts if
you want them to last.
