Third Kit Heat Test
Disclaimer: The results presented are an actual
test performed on a fully loaded Dell Dimension 2350 system and are for
informational purposes only. Adding any new components inside the case will
increase power consumption and your results may vary based on your system's
configuration and use. iResolved cannot be held responsible for any damage done

This test was conducted to determine the
heating effect of adding a third hard drive into the system. As expected the
drive temperatures increased by 3 degrees Celsius (5.4 deg F), but are still
well within the recommended operating range of hard drives. As suggested below,
the least used or backup drive should be placed in the center position.
Dell Dimension 2350: a stock computer with three hard drives configured
as shown on the right with round IDE cables, two DVD-RWs, and all three PCI
slots filled, one with the IDE controller card described below.

middle drive temperature increased by 3 degrees Celcius, and the primary drive
nearest the front of the case showed no appreciable heat increase.
Conclusions and recommendations:
The middle drive temperature's increase is
relatively small and within the recommended operating temperature of the drive.
The recommended temperature varies by manufacturer, but is usually between 5-55
degrees Celcius with some newer drives operating safely up to 60 degrees. For
instance, check these links to
Since the middle drive is positioned between two other drives, it will receive
less airflow, even though designed to increase exposed surface area. As such, it
is recommended that lower RPM drives or lesser used drives are placed in the
middle and that the temperature is checked regularly.
