I just purchased an ASUS P4G800-V board and when I have the chassis
fan connected
the system will not POST. Just hangs with power light and HD light.
No beeps, nothing. When I disconnect the chassis fan system POSTs
and boots fine. Tried second fan, same result.
?????? Anybody have any ideas? RMA time?
Thanks.

Are you attaching the fan's connector backwards onto the motherboard's
header pins? Are these 2-wire or 3-wire fans? If a 3-wire fan onto a
2-pin header, could be you're connecting them backwards. If a 2-wire
fan onto a 3-wire header, could be you are offset by a pin (plus that
fan will look to always be not spinning). Does the printing on the
motherboard where you are connecting the fan say "CHA" (for chassis)?
Are you connecting the chassis fan to a header on the motherboard or
inline with the power supply wiring harness?
With the fan removed so you can boot up, go into BIOS and check if there
are triggers for fan speed, especially for wherever you are connecting
the chassis fan. If that works, then see if you can also set BIOS to
let the fan rotate at a much slower speed before it triggers a shutdown.
Maybe your fans aren't spinning fast enough, especially if stealth fans.
