Hi everyone, After I completely disassemble my Mac - even board was out, so no dust at all and new thermal paste, when I put everything together my bottom back fan (just behind RAM’s) spinning on 100%. A check if is everything connected and I can see any issue. Any idea ? Thanks a lot
Hi I had this issue with one of my Macs and it was dust stuck in one of the fan connectors So my advise would be to reseat the connectors and blow into them to remove any small dust particles Hopefully this answers your questions Thanks:-)
I would run the diagnostics from the original grey disk for this system or down load it from Hardware Test (AHT) & Apple Service Diagnostic (ASD) disks as Apple so kindly removed all of the old T/N’s and software from their site. Thank Apple for forgetting all of the older systems still in service!
