About 2 months ago I added and external SSD to my 2014 iMac and with the proper software was able to convert to a fusion drive. All of it is working very well, especially Lightroom, which appreciated the speed boost. Now I am getting a "whooshing" sound which could be a fan. Is the sound related to my adding the SSd or is my fan bad and is it going to pose an overheating problem. I downloaded a software fix which seems to do nothing or at best very little to tone down this annoying sound. Any ideas would be appreciated.

MacNN itself is no longer. The forums, though, will remain alive so long as they can pay the bills.

A fan running, to me at least, is more indicative of possibly either a sensor failing or something running hotter than normal, and not the fan itself failing.

Temperature sensing issue on the new drive. You can either tell the fans to slow down manually (which I don't recommend) or get a kit like this:

External SSD as part of a fusion drive. a) v. odd idea. Much danger of disconnecting drive and loosing data, etc.

Still... unlikely to be drive temp sensing issue as the iMac should still be getting temps from the original hdd. More liley an internal temp sensor is failing?
