CPU fan reads 0 but all fans going at full
I recently reflowed a faulty graphics card from a late 2009 iMac (successfully) as per JDW's excellent YouTube found elsewhere here.
However in reassembly all the fans are going. Istats showed CPU fan as zero. Did several SMC resets. Checked everything. Not due to missing resistor seen in other similar cases.
However during reassembly this piece was seen in bottom of case. Can anyone idenify it or suggest anything else to try? https://drive.google.com/open?id=0B1SD5V... and https://drive.google.com/open?id=0B1SD5V...
Is this a good question?
