Chosen Solution
I bought this iMac used with a broken CPU fan (Macs Fan Control says 0 RPM) and CPU overheats easily . I bought and installed a used CPU fan off Ebay, but it didn’t fix anything. I’ve already tried resetting SMC. Is it possible for me to tap the CPU fan connector wire into the ODD fan connector or the HDD fan connector? (It’s actually an SSD now.) I’m willing to remove the power from the other fans if you think that 1 socket on the logic board shouldn’t power 2 fans. Thanks!
yes!! yes I have this setup right now when the HDD fan connector blew so im using the power from the ODD fan connector to power both fans ! its been like this for nearly a year and never had an issue
