Greeting everyone! I just completed a PC build for my brother. This is the first time I have used a Gigabyte mobo. The system went together without any issues at all. Here is a run down on parts.
GABYTE GA-EP45-UD3R
Intel dual core CPU
WD 500 GB hard drive
ATI graphics card
Zalman CPU cooler
DVD RW drive
Corsair 620 wt PS
My question is this. When I first powered the system on, all the case fans spun up, but the CPU fan was completely still for about three seconds, and then started up. I went ahead and entered the bios to look around. CPU temp was a steady 20C the entire time I was in the bios. I went ahead and shut the system back down. Later, I started the system up again. Same thing, all fans powered up, but the CPU fan sat there for 3-4 seconds before spinning up to full speed.
Ok, I did some looking around in the mobo hand book, and found the "Smart fan control". I disabled that, but the CPU fan still sits for a few seconds before starting to spin. Once it's spinning, it runs nice and steady, and I can control the RPM with the speed controller that came with the Zalman.
Does anyone know why this happens? Is there some issue with the board? Could the CPU fan header be damaged?
Aso one other question. I originally had one of the case fans connected to the "SYS_FAN2" connection on the mobo. The fan connected to this header did not spin as fast as the other fans. I checked the RPM in the "PC health status" section of the bios to confirm this. I then connected the fan directly to the power supply, and it spins just as fast as the others. Is this fan header not getting enough voltage??
I appreciate any help on this!! Thanks!
