Help: On crucial PSU-CASE-MOBO wire connections

[helmgt01]

MY equipment:

Bad Axe mobo revision 305
OCZ gamerxtreme 700 watt
and Cooler master 'Mystique' with side panel window...

I am now connecting all the little case wires to the mobo...this is hell...most I'm sure I've placed correctly, but a few I'm not too sure about...

1)not sure how to tell the positive and negative on the hd led connection (on plug head there is an arrow-is this positive?)
2)can't find where to connect 'PCspeaker'-step eight
3)I've connected the 'MAIN' 24 pin and the 2x4 CPU pins...but I can't figure out which connection from PSU connects into the 1x4 pin (and I don't know what that pin is even for-i.e. no title in manual)

Please help

1) I thought that it didn't matter as they were nonpolor or w/e
2) Does your case have a speaker in it? If not, don't worry about it
3) That 1x4 may just be a standard molex connector.

[helmgt01]

The drawn diagram shows to connect all three-is the 'Molex' necessary, if that is what it is.
No case has no speaker.

[helmgt01]

the diagram for the hd led shows a neg and a pos...wait I guess I can assume the 'white' to be negative

The colored wire is usually power and the white or black wire is the ground. If the LED doesn't light up the first time, just flip the connector over 180 degrees.

Intel motherboards have a small round piezo speaker already built-on the motherboard...it's by the black SATA ports. No need to connect the case speaker.

Try reading the motherboard manual again to see if you even need to plug in a 4 pin molex power connector from the power supply or not. See if there is a electronic manual on the motherboard CD...it'll be more detailed than the paper one you get with the motherboard.

ok, now need help with the 'jumping' the cd drive. i don't really know anything about this. on top of my cd drive there is a diagram for three selections which correspond to the pins in the back...1=CSEL, 2=Slave, 3= Master...on the master pins, there is some sort of small covering or black casing...need some help from there.

Oh, only using one cd drive.
And I can't figure out which line from psu to connect to the 'power' on floppy...my PSU has two heads that look like they would fit, but one is labeled 'P7' and the other is 'P11'...

[helmgt01]

Also need help on connecting my flash drive...two connections in back of drive...end of each cable that came with OEM flash are 1 row of 5 'female' pin connectors...

What kind of IDE cable are you using? A 40 wire or an 80 wire?

If you're using a 40 wire IDE cable, set the jumper to Master.

If you're using a 80 wire IDE cable, set the jumper to CSEL and connect the drive to the black connector on the IDE cable. The blue connector goes to the motherboard.

Doesn't matter...use either one. But make sure you connect it right-way-up or you'll get sparks and smoke when you power up.

Don't connect the USB card reader until after you've installed Windows.

[helmgt01]

Not sure if it's 40 or 80 wire for cd-what is the difference?
and I've got windows installed, but still don't know how to connect the flash drive
One problem: think I'm running hot-

Cpu fan speed 1500 (fluctuates/adjusts itself between 1380 and 1550)
Front fan speed 720 (120mm)
Rear fan speed 660 (120mm)

CPU temp=55-6c
Internal=43c
remote temp=38-9c

v12=12.250v
v5=4.954v
v3.3=3.302v
v1.5=1.477v
vccp=1.289v

Are these numbers good (except I know the cpu is too hot)

Here are major components:
Ocz 700 watt gamextreme
conroe e6400
Bad Axe mobo
sapphire x1900xtx
Corsair 2x1gb xms2
cooler master mystique case w/window

Oh and sorry about the multiple threads...won't happen again.
I will use this thread for all questions with this build...you can delete the other two threads if you like (if you can)..

The 40 wire IDE cable is designed for slower data transfer rates. The 80 wire is designed for faster data transfer rates.

If the surface of your IDE cable has pronounced ridges, it's probably a 40 wire. If the surface appears to have a finer surface, it's a 80 wire. Follow the instructions above for the jumper setting.

Oh, you did? See, this is why it's important to keep all your problems with this new build in one thread. I replied to another of your threads and now feel I wasted my time in answering it since you seem to have found a solution already.

The card reader connects to the USB headers on the motherboard. See the motherboard manual for locations.

The voltages look fine and the other temps appear to be okay. Double check that the CPU heatsink is installed properly. Pull the motherboard from the case and check to see if the pins are fully inserted through the motherboard and locked down properly. Look at this LGA775 heatsink installation guide.

Fan was not 'clicked in correctly'...reinstalled it...now running at 73c and rising...I quickly shut down.

[helmgt01]

ok reconnected...fan is (i think) installed properly, but thermal padding isn't really melted all that evenly-very splotchy, and some leakked out slightly over sides.
CPU seems to be holding at 55c
internal temp to 43c
remote holds at 36c

How can I adjust the CPU fan speed to 1800...it fluctuates now between 880 and 1020

Did you look in the BIOS to see if you can set the fan to either Low, AUTO or High?

Cricket

[helmgt01]

Under 'boot config' I only have optionto 'enable' or 'disable' CPU fan control, Sys fan control.
under tthat is the option to set lowest fan speed to either 'slow' or 'off'
Then 'max cpuid value limit' enable or disable
and finally display setup prompt on or off

[helmgt01]

One last piece of hardware I'm about to install: Creative labs x-fi extreme music sound card and the logitech 5.1 500watt crazy-crazy speakers...

I need a link or some real-time aid with the sound card...can't find instructions on creative lab site...don't know if I only need to connect the PSU to board (already installed on mobo)...several connection pin sets on the sound card.

What is that option set to now?

Originally Posted by helmgt01 under tthat is the option to set lowest fan speed to either 'slow' or 'off'

Did you try setting that option to "Off"?

Cricket

[helmgt01]

CPU and SYS fan conrol are both enabled
Lowest fan speed is set to 'slow'-I'll turn it off and reboot
I also sometimes have to manually 'push' my rear fan at startup-it sometimes stutters back and forth without begining to rotate.

[helmgt01]

After boot, processor fan remains at 1080
and all same temps

[Cricket]

Try disabling the CPU fan control. That should allow the CPU heatsink fan to run at full speed.

Where is the rear fan getting it's power? From the motherboard or from the power supply?

The sound card gets it's power from the motherboard. No need to connect anything from the power supply.

Yes disabling the CPU fan control set fan to 1860, processor Temp now steady 44-45c

The strange thing is the 'lowest fan speed' option controls the case fans and when turned 'off' they don't run, and the only other option is 'slow.'

Rear fan is connected to Mobo.

Did you try disabling the CASE fan control option? Personally, I would connect case fans directly to the power supply, not to the motherboard.

OK, disabled sys fan, now case fans are running at 1320 front and 1260 rear.
But, why would it make a difference to connect the fans to PSU rather than Mobo?
Processor holds at 50c (processor fan jumped to 2040)
Internal 38c (improvement)
Remote @ 36c (what is remote anyway???)

Some fans draw a lot of power and this can disrupt the motherboard power circuit and cause system instability. I just rather not take any chances.

Ok fans have switched, but now bios doesn't read rpm
Temps still holding
CPU 50c
Internal 38c
Remote 35c

[Cricket]

I don't see that as a problem...personally I don't monitor the case fan RPMs on any of my computers...don't see the need. You can always just put your hand by the port to feel if the fan is working or not.
