In Table 4.3 (Fan Speed and Corresponding Revolution per Minute), as
shown above, the result was that the fan speed increases as temperature
increases and vice versa. From the data, it can be seen that the fan speed varies
because the measured RPM (revolutions per minute) for every fan speed is
varying.
Testing on Inflow Direction of Air versus Outflow Direction of Air:
The purpose of testing the inflow direction of air versus the outflow
direction air is to determine which is better; inflow or outflow, as the researchers
conducted a series of testing on the temperature inside the CPU. The researchers
tested this for both instances wherein the device was not installed and when the
