I've recently lost my SSD chip on my 11,3 MacBook Pro Retina 13". I bought a used, compatible SSD chip on eBay, and installed it. Immediately the fans went up full speed. This new chip was a MacBook Air stock chip.

I borrowed a rMBP SSD chip from a friend for testing. Fans worked normally.

I have done SMC reset and PRAM reset procedures. They did nothing.

So far I've been using Macs Fan Control to keep the fans quiet. The computer does not overheat at all. It's just the fans acting crazy when this disk is installed. If I swap it for another one, they work fine.

I've erased the disk and installed Sierra from scratch, and followed it with an SMC reset. Nothing.

Why would I get different fan action by changing an SSD drive for another? Any way to fix this? Could it have anything to do with the EFI partition?
