Attempting a newbuild but can't get power to the fan. what happens is I connect the psu and press the power button on the case. The fan turns for a second then stops. I immediately disconnect the pwr each time so as not to fry the cpu and sometimes when i do this the fan suddenly starts up at full speed for a split second then stops as power is withdrawn.
Thing is, it cant be psu as i have tried 2 with same result. Getting really frustrated, any ideas? Could mobo be buggered?
Intel e4300 with retail heatsink and fan Gigabyte LGA 775 - 965p mobo 500w (20 + 4 pin psu)
answers: yes the heatsink fan is connected to the cpu_fan connector on the mobo.
Baldtaco: Im really not sure how to run the heatsink/cpu fan from a molex leading from the psu as they are not compatible - psu molexes are female same as the fan molex, you would surely need an adapter fitted with 4 pins like the mobo connector, that begs the question, why not just use the mobo pins?..
It can put too much drain on the mobo. Without knowing exactly which fans you have I'm guessing, but I know some of my Deltas and two of my Thermaltake state very specifically that you will damage the mobo if you try to run them from a header.
