CPU fan failure bypass

Hey LTT,

 

The Dell CPU fan from my Dell Optiplex 210L broke, so I removed it and added a fan wired to the PSU, which works fine. However, it still thinks the old fan is in their and gives an error message saying “Alert! CPU fan failure”. This means that every time I turn on the computer, I have to press F1. This is normally not a problem, but when I am using the PC as a server, I have to walk down 2 floors to press F1. How can I bypass this?

did you plug the replacement fan into the cpu fan header, should be able to and that should resolve it... if not, in the bios there should be a section for fan monitoring, should be a spot to ignore cpu fan speed, pretty sure that should take care of it

Plug another case fan on the CPU fan connector

There might be an option in bios to disable it but am not sure. The fan method will work tho.

 

It does this beacuse it thinks that your CPU fan isn't spinning beacuse nothing is connected to it

The CPU fan connector to the MOBO is a weird 5 pin dell connector. 

Ok, try the bios trick, should be something that says cpu fan speed or cpu fan monitoring or something like that and have options for multiple fan rpms or ignore
