    If that fan does not need to be monitored by a temperature program, keep it hooked up to the PSU.
  3. By reading threads around techspot it appears if you run your CPU fan off the plug on the motherboard you may have compatibility issues eg: certain mobos will only run certain fans and the PSU not as fussy. Sound like a Marketing Strategy. So best to do as our Irish friend says and run it off the PSU :giddy:

    Your board may have a safety feature on it that will prevent the board from posting until the jumper for the fan is plugged in- to prevent the chip from roasting during a post. Experienced system builders will shudder at the thought of that *ahem lol* You can get a power splitter that includes mobo jumpers and 4 pin molex pwr connectors.

    Hope this helps

    Cheers
