A computer should be able to withstand 100 percent CPU usage without
anything bad happening. And run that way forever.
You need to fix your CPU cooling, as virtually any computing activity
could cause short periods of 100 percent usage. In its current state,
the computer could shut down when you make a change in a lengthy
Microsoft Word document. What you're doing, is like running a computer
with a guillotine positioned above your head.
If you fix the CPU cooling, the CPU usage will not present a threat to you.
A PCI serial card, can use interrupts for data transfer. That means
zero CPU usage, when no characters are being received or transmitted.
But using such a card, is not a substitute for fixing the cooling
problem. The computer can still shut down, even if you stop using the
USB-serial adapter. And it will shut down, when you least want it to,
with unsaved work in memory.
