Hi all,
Briefly: It looks like I POST ok but the CPU Fan isn't spinning and isn't detected.
The Details: I just did an pseudo-out-of-case build with the following:
Intel Core i5-3570K
CORSAIR Builder Series CX600 600W ATX12V v2.3
CORSAIR Vengeance 8GB (2 x 4GB)
Western Digital WD Black WD1002FAEX 1TB 7200 RPM SATA 6.0Gb/s 3.5"
Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case
I assembled the CPU/CPUFan, RAM and Mobo out of the case, but put the hard drive and PSU in the case. I plugged in the case's LED, Reset, and Power switches and the little speaker. I plugged in the 24-pin ATX power cable, and the 8-pin CPU power cable. I even plugged in the SATA cable for the hard drive. I then plugged the power cable from the PSU to the wall. I switched on the PSU and the CPU standby LED on the mobo lit up (green). I then pushed the power button on the case to boot up the mobo. I heard a single beep, followed by the beep sequence for lack of VGA cable (oops) so I plugged in my VGA cable to see the splash screen. At the bottom of the screen is said two things:
1. No keyboard detected (makes sense cause I didn't hook one up)
2. No CPU Fan! (uh... what?)
I checked the CPU Fan to see if it was spinning, and it was not.
I powered off the system through the power button on the case, switched off the PSU, and unplugged the power cable to the PSU. I then started checking my connections.
1. The CPU fan is plugged into the CPU_FAN plug on the mobo.
2. The 24/8-pin ATX/CPU power cables are fully and firmly in place. They are not loose.
The way I see it, I've either connected something incorrectly, one of my parts (fan, mobo, or PSU) are faulty, or there's some weirdo-BIOS thing I have to do. I called the ASUS customer support, and the dude seemed pretty clueless as to how this is possible... though he did suggest I plug the CPU fan to the PSU directly (if possible) to eliminate the possibility of a faulty fan or PSU. I haven't done this yet, but seems like a reasonable idea...
Anyone ever seen something like this before? Any thoughts or solutions?
Thanks in advance!
