===Rounded cables===
Most older PCs use flat [[ribbon cable]]s to connect storage drives ([[AT Attachment|IDE]] or [[SCSI]]). These large flat cables greatly impede airflow by causing drag and turbulence. Overclockers and modders often replace these with rounded cables, with the conductive wires bunched together tightly to reduce surface area. Theoretically, the parallel strands of conductors in a ribbon cable serve to reduce [[crosstalk]] (signal carrying conductors inducing signals in nearby conductors), but there is no empirical evidence of rounding cables reducing performance. This may be because the length of the cable is short enough so that the effect of crosstalk is negligible. Problems usually arise when the cable is not [[Electromagnetic shielding|electromagnetically protected]] and the length is considerable, a more frequent occurrence with older network cables.

These computer cables can then be cable tied to the chassis or other cables to further increase airflow.

This is less of a problem with new computers that use [[serial ATA]] which has a much narrower cable.
