The XFX Radeon HD 5830 video card XFX HD-583X-ZNFV has an overall length of 10.25 inches, so this isn't a little card by any means. In order to keep the XFX Radeon HD 5830's temperatures in check, XFX uses a custom cooling solution that features a 70mm fan. The heat sink assembly has a pair of heat pipes with about 120 fins soldered in place. The fan is a 70x70x15mm fan that is rated for .43 Amps and a maximum speed of 4000RPM. For a small fan it move a decent amount of air, at maximum speed it will push 35.5CFM through the fins of the heatsink. The heat sink itself has a copper base and the pair of copper heatpipes that run through the base have been soldered into place.
