The fan modules cool the power supplies and storage system by drawing air in
through various openings in the storage system and blowing it out the back. However,
the fan also draws dust and other particles into the storage system, causing contami-
nant buildup, which results in an increase in the storage system's internal
temperature and interferes with the operation of various system components.
To avoid these conditions, Dell recommends keeping your work environment clean to
reduce the amount of dust and dirt around the storage system, thereby reducing the
amount of contaminants drawn into the storage system by the power supply fan. In
particular, you should keep the exterior of your storage system clean.

Temperature extremes can cause a variety of problems, including premature aging
and failure of chips or mechanical failure of devices. Extreme temperature fluctuations
can cause chips to become loose in their sockets and can cause expansion and con-
traction of disk drive platters, resulting in read or write data errors. When you perform
a low-level format operation on a hard-disk drive, it is important to ensure that the
drive's surrounding temperature is at or near the temperature at which the drive will
be operated. Failure to do so can result in relocation of the tracks on the disk platters.
