Hi, 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…
What I can tell you is the little metal part you have in your image is one of the alignment pins for the display. Nothing to worry about. As to your fan issue depending on your model you could have either a mis-connection or a bad fan. We really need to know what you system is to go further. Update (06/29/2017) I gather you are still having problems. Can you give this app a try: TG Pro it does a better job of listing all of the sensors and fans with there running status. Paste a screen capture of the main screen (all of it) so we can see all of the sensors and fans details into a fresh answer and then click update. From what it sounds like you may have damaged one of the GPU thermal sensors or have a mis-wired fan.
Hello, I have the same problem. How did you solve the issue?
