Replaced Power Supply - Multiple Sensor Failures
Had an iMac (27-inch, Mid 2010) suffering a power supply failure. Replaced the power supply and now the unit powers on, but the fans run constantly at 100%. Diagnostics show 17 of the 25 sensors (most of them temp, but a couple of voltage sensors) as "can't read". Trying to figure out if the sensor failures are due to a problem with the new PSU, or if they are simply a secondary issue that couldn't be diagnosed until the PSU was replaced. Any thoughts?
Is this a good question?
