ML330 Adding 2nd Processor and PWM Fan
I found the pin out for the fan connector but where can I find the pin out for the 4-pin motherboard fan connection for the ML330? I'd like to know which which pins on the ML330 are 12v, ground, tach and PWM.
Here is the fan being used:

Better yet, has anyone done this before?
Thank you for any info.

Re: ML330 Adding 2nd Processor and PWM Fan
... personally I'm not familiar to MLL330 G3 pin allocation, however what you can do:
pull one wire at time from working one and check how it does change speed and functionality, do not rely on coloring, you can damage chipset, I hope your server is out of warranty at this time?, if not you might consider to purchase new heatsink and fan assembly, you can find sometimes around $40 or from parts surfer $78
other way test for -+ power negative with digital volt tester, basic knowledge will be enough
third party fan might have green white black or red black white, some of them designed for dual speed some of them use sense cable, be careful to not damage sys board as it might affect primary fan too, third party fan with slow speed rotation might affect chipset and it could translate it as error and hundreds of log in IML or event viewer

Re: ML330 Adding 2nd Processor and PWM Fan
I don't know the pin-out of ml330 for cpu fan, but if is a 4 pis, there is only one way to fit the 3 pins connector...
I've assembled a few thousand of systems and over all mother board there is only one way to fit the 3 pins connector in a four...
bye.

Re: ML330 Adding 2nd Processor and PWM Fan
tomorrow morning I'll be in office.
I'll give you an answer.
right now it's 21:30 ...

Re: ML330 Adding 2nd Processor and PWM Fan
4 pins
Ground
+ 12 V
Installed ├в loop back from ground verifies if fan is installed.
Faults ├в collect all fan failures and report to Software
First three would be hardware level; along loop back can be detected trough software too
I hope TJK can confirm exact pin allocation, as I can't find it

Re: ML330 Adding 2nd Processor and PWM Fan
yes Oleg; you are right.
I confirm.
Also, taking a look at your photo (xxcdfdrr) it seems there is only one way to insert the connector.
like aver all MB I've seen in my life.
in addition: making a mistake in connecting a fan, no possibilities of frying the MB.
the fan is a passive component.
only a few things may happens.
one of this is what, correctly says Oleg: hundreds of errors...
another, may rotate in revers mode.
be patient... you can try all the combinations of four pins: only 4!=24.
ok, I'm kidding.
I think nothing may happen.
connect you fan!
Bye.
Good Morning again.
