Yesterday, I replaced the old AMD Sempron 3400+ with an AMD Athlon 64 3700+ San Deigo. After everything was install, the screen tell me that the CPU cooling devide did not work; and for safety, the computer shut down in like 10 seconds. I checked the fan connector (3-pin fan), power supply, everything was in place. I still see the fan spinning???
Oh, there are two fan connectors-3pin on my motherboard, one is brown and the others is white. THe AMD fan-connector of Athlon 64 is brown so I connected it to the brown 3-pin, and it spin. I did try to connect to the white one but it did not spin)
So I wonder what is happening? Does anybody have an explannation or solution?
Thanks for helping!
