Thanks for answer but I have replaced product with another already.
Sadly performer C have 3 pin cpu connection which causes Windows 10 often throw error message (Your CPU Fan doesn't work properly. You must turn off your system right now and check it.)
Extender cable (not sure how to call it instructions gives so little info about it.) have 4 pin but still produces same error. I can't sell this unstable PC build.
Regards.
