If the foam is in the path of the intake or exhaust air, then there is a
risk of pushing the CPU thermal protection into auto shutdown and any
consequent thermal damage. If the fan is running constantly at high
speed, you should open Task Manager and determine what, if anything, is
running in the background that is creating a CPU load, then disabling
that application or service (if it makes sense) in msconfig (run
command, type: msconfig, select startup tab). The system idle process
is the rest state of the CPU and should normally be greater than 95%
unless you have started a application that loads the CPU.
