My Seagate 1TB failed and the CPU fan started to run 24/7 at around 2,000 rpm. I had the HD replaced during the replacement program, since it failed a 1 week before they annouced the program. The replacement Seagate 1TB failed six months later. So I replaced with a Seagate 3TB version. I still have the CPU fan issue, with it running at 2,000 rpm 24/7. I use SSD Fan Control app to help reduce the fan speed, but would love to have this back to normal. Any ideas?
