iMac Intel 21.5″ (Late 2009-Mid 2011) Hard Drive Fan

Replace a malfunctioning Hard Drive Fan to fix overheating problems and keep your Model A1311 Late 2009 to Mid 2011 21.5″ iMac running quietly.

An aging fan may become noisy and inefficient or simply fail and stop spinning, leaving your computer to overheat and eventually damage your processors.
