The purpose of this research was to investigate the effects
of different RAM amount and fan failure on bulk CPU
temperature rises while operating under a heavy
computational load. Two sets of experiments, each with
varying amounts of RAM were carried out under CPU cooling
fan-on and fan-off conditions. A personal computer with an
Intel Pentium I11 CPU was used to conduct the experiments.
The computational load was the multiplication of two
dimensional matrices (3100 by 3100) containing double
precision numbers. To monitor temperature rises, sensitive
thermocouples were installed on CPU Heat-sink, the RAM
module, and the hard disk.
This paper demonstrates that CPU temperature increases
as more RAM becomes available to perform the computation.
The authors hypothesize that the increase in CPU temperature
is correlated to full CPU utilization to carry out a heavy
computational load.
