Please help-New Rig using a Lian Li case, Totally confused

post #1 of 8
Thread Starter 
Thank you for taking a moment to assist me. I'm a complete amateur when it comes to building a computer, having only built one other system several years ago.

The Gigabyte Chassis I used back then was apparently a "computer case for dummies" because everything was labelled and the instructions contained massive numbers of step-by-step pictures. I just purchased a Lian Li PC-X900, and it is a much more complex beast.

I'm having two problems.

The first problem is, I'm at an absolutely loss as to how the 5 case fans are supposed to be connected and powered. There is a fan speed controller attached to this case, and it has just added to my confusion.

My motherboard is a Gigabyte GA-P67A-UD4-B3. It appears to have SYS FAN1, SYS FAN2, and PWR FAN.

On the Lian Li case's back, I have this controller labeled fan 1, fan 2, fan 3, fan 4:





In the front I have 3 fans:



EACH fan has these connection:



Can someone explain....everything.....in the most simplistic terms possible?

you should see a 3 pin connector from each fan. connect each fan to the motherboard. i don't think it matters what pin you connect to. just make sure the cpu fan is plugged into the cpu spot on the motherboard.

Thanks for the reply! The problem is the mobo only has 2 fan connectors, but I have 5 fans. I'm starting to think that I'm supposed to link all of them into the fan controller, and bypass the motherboard entirely.

Those are pass through connectors for a 4 pin molex plug. They are plugs on your power supply. Take a male plug from you psu and "Do it like they do on the Discovery channel" by plugging it into a female plug. You can daisy chain them together to help keep cable neater.

You can do that too. that way you have some control over airflow to noise ratio.

No no no no. You plug the fans into those 3 pin cords in the first picture. Don't use the 3 pin to molex adapters on each fan. And then you can power all of them using that molex in the first picture.

If you plug it into the motherboard you won't be able to use the case's built in fan controller.

I had to do this with my case.

I didn't realize this case has a fan controller built in. My bad. Definitely plug the fans into 3pin cables from the fan controller.

Thank you for the replies. It worked like a charm! Unfortunately, the system boots up for two seconds, shuts down, and then attempts to boot again looping forever.

<sigh> I bought a Seasonic 750 watt x-series PSU, so that should be more than enough juice for a GTX 580, 8GB of ram, and i5 2500 and 1 hard drive.

Looks like the birthday present for my brother is going to be late.
