Depending on your mobo, you can turn it off in the bios. Or what wou can do is plug a cable into the cpu fan connector on your mobo (even if it doesnt have a real fan attached to it). When it happens to me i have a lot of parts in hand so i just change it but u can fix it the way i just mentionned as well. Or you can plug any fan in that cpu fan connector on your mobo.
Sorry but I don't understand when you say "I can plug any fan in the cpu fan connector". If I don't plug my CPU Fan into the CPU fan connector, my fan on my CPU won't run. How does that solve my problem?
Mu CPUs - on both computers - are working fine. Its just this error we're getting.
