Other Purposes
Fans are, less commonly, used for other purposes such as:
- PCI slot fan: A fan mounted in one of the PCI slots, usually to supply additional cooling to the PCI and/or graphics cards.
- Hard disk fan: A fan mounted next to or on a hard disk drive. This may be desirable on faster-spinning hard disks with greater heat production. As of 2011 less expensive drives rotated at speeds up to 7,200 RPM; 10,000 and 15,000 RPM drives were available but generated more heat.
- CD burner fan: Some internal CD and/or DVD burners included cooling fans.
- Memory fan: Modern computer memory can generate enough heat, especially when overclocked, that active cooling may be necessary, usually in the form of small fans positioned above the memory chips.

Famous quotes containing the word purposes:
“What we call a democratic society might be defined for certain purposes as one in which the majority is always prepared to put down a revolutionary minority.”
—Walter Lippmann (1889–1974)
“A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.”
—Jacques Barzun (b. 1907)
