To run the experiments under the fan-off conditions, the
power supply to the fan was disconnected. thus simulating the
fan failure condition during the execution of a heavy
computational load. A program written in LabVIEW recorded
four temperature measurements (Ambient Room, CPU. RAM,
and Hard Disk temperatures) at one minute time intervals. A
spreadsheet program in Microsofta Excel was used to import
the data for graphical and statistical analysis.
Performance graphs [4] of CPU utilization, memory usage,
data paging, hard disk data transfer rate were obtained at the
beginning and during each run. The main motivation for
monitoring the above parameters was to investigate possible
correlation between CPU temperature-rises and RAM usage
under a heavy computational load.
