I'm using this mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

So I just build my first computer but there are a couple things I can't seem to figure out. When I went to plug in the usb's from the front of the case there are a few usb slots 1 of them is red and the others are blue, which one should I plug this into, I didn't want to guess and have something bad happen.

I'm also not sure where to plug in the case fans on the mobo, there working because they have power but I'd like to be able to control them.

I've read through the mobo's guide and I can't figure it out, any help would be awesome, thanks.

Down load manual here: http://download.gigabyte.us/FileList/Manual/mb_manual_g...

Goto Page 22 of manual where it shows board layout and internal connectors.

You do not have any USB 3.0 front panel connector on that motherboard so if your case has USB 3.0 20 pin connector you have to leave that disconnected.

Connect USB 2.0 10 pin connectors to any of the four USB 2.0 10 pin headers on the motherboard , F_USB1, F_USB2, F_USB3, F_USB4 (item 12). Please note: According to Gigabyte website the F_USB1 is able to be used as a power supply for charging cellphones and other devices so be sure to use that one only for the front panel if you plan to charge devices on your computer.

Connect case fans to SYS_FAN1 and/or SYS_FAN2. Use the one that your fan reaches most easily. If you have three fans you can also use PWR_FAN for one of them.

If you have more than three fans you can use a power adapter to connect the fans directly to your PSU using this http://www.newegg.com/Product/Product.aspx?Item=N82E168... or something similar.

Or you can put two fans on one fan power connector using this http://www.newegg.com/Product/Product.aspx?Item=N82E168... but don't put more than two fans on any single connector on the motherboard so you don't burn it out.

Thanks, I plugged in the the usb and that is working properly. I also plugged in the fan to SYS_FAN1 and for some reason after I did that the computer wont turn on. I press the power button and the led turns on for a second then turns off then if I try to turn it on again theres nothing. I unplugged the fan and it turns on just fine, why would it be doing this?

The fans are connected to 1 wire through two power sockets coming out of that wire has a 4 prong insert so it will only fit into sys_fan1 since the others only have 3 prong inserts, what did I do wrong? The fans are working properly, there on, I just have no control over them.

Your problem with using SYS_FAN1 sounds like you might not have it lined up correctly. Make sure that you are orienting the cable correctly. The notch in the fan connector must slide easily past the tab on the connector.

Also, SYS_FAN1 is a four pin connector because it can be used with a PWM fan. SYS_FAN2 and PWR_FAN are both 3 pin connectors and therefore cannot control a PWM fan. You can use a non-PWM fan with a PWM connector but make sure that you only use the three pins that line up with the tab.

What kind of fans are you trying to use? List manuf. and model or link so we can look at it. Actually, complete system specs would be really helpful. CPU, PSU, Graphics card, HDD, SSD if any, Memory, etc.
