Check the OEM number on your old cable to be sure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy are the fans at full speed?\u003c\/strong\u003e\u003cbr\u003e\nWithout a valid signal from the HDD temperature sensor, the SMC defaults the fans to maximum as a safety measure. A new cable with working sensor solves this immediately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use an SSD with a separate sensor instead?\u003c\/strong\u003e\u003cbr\u003e\nYes, but you still need a working SATA cable. Software like Macs Fan Control also helps, but a good cable is always the cleanest fix.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Does this cable fit all A1312 years?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Mechanically identical for Late 2009, Mid 2010 and Mid 2011.
