Hi team, just swapped out the old spinner from a late 2009 imac with a SSD, but now the CPU fans blast full noise. Note, this is NOT the HDD temp issue. I used an OWC sata temp adapter and iStat Pro is telling me it is the CPU. Pretty sure I connected the temp next to the display port cable and there is a reading of CPU temp and fan speed. Tried SMC reset and PRAM. Gann control software doesn't show it down. About to try OS install. Any suggestions or tips from experience anyone? Any/all help appreciated.
