Hello
Can some one tell me where do i plug the antec sonata PSU Fan monito into. it is a 2 wired connector.

what if i dont plug it in?
what is it used for?
my mobo is a gugabyte 81875 ultra. can you tell me where it goes?

You dont need to have it plugged in, it will run fine unplugged. It just allows you to monitor how fast the ps fan is going.
With the 380 TruePower that came in the Sonata I had back in the day...I did not connect it when I first put the box together.
Seemed after connecting it to the motherboard the fans inside the power supply turned more RPM...Which was one of the gripes I have with the TruePowers.
Power supply and any fans connected to the "Fan Only" molex connectors turn way to slow for my taste.
If you like a quiet system you may like using the "Fan Only" connectors for your case fans.
And yeah CrispyFried is right...It is not something you have to connect.

thanks for all the replies
i did not quite understand, what do you mean by
"Power supply and any fans connected to the "Fan Only" molex connectors turn way to slow for my taste. "
does the power supply need to be connected to the "fan only" molex connector?

no, the power supply does not power itself.. DO NOT PLUG THE FAN MONITOR INTO THE MOLEX CONNECTOR.
According to the PDF manual from Gigbytes site on page 25 they show 5 as the PWR_FAN located at the end of the IDE slots...4 is shown as SYS_FAN right above the SATA connectors.
Just look for the CMOS battery...They are both located around it.

so the power supply does not need to be plugged into the fan only molex connector(creating some sort of close loop), correct?
and i will just leave the fan monitor unplugged,
i have a gigabyte 81875 ultra
looking at the datasheet for the mobo, i found a PWR_FAN header, is that the one that i need to plug the PSU Fan monitor into?

The "Fan Only" are the plainly marked 4 pin molex connectors coming out of your power supply...The fans connected to these connectors will increase or decrease in speed according to system temps.
It is very important that you locate and are aware of the "Fan Only" molex connectors...They are for fans only...Do not use them to power your hard drive, dvdrw or any other componet in your box except fans.
The 3 pin connector if connected should be used in either of the fan headers located around your CMOS battery.

when you say, "The fans connected to these connectors will increase or decrease in speed according to system temps. " does this mean that the molex connectors will output variable voltages dependent on the system temperature. and the variable voltages will be generated by the Power supply, so in other words it is the PSU which has the temperature sensing intelligence?
i see SYS_FAN and PWR_FAN around the battery, i will plug my 3 pin connector into one of the two?

The PSU Fan monitor is a three pin connector that has two wires coming out of the power supply...If memory serves me right one is blue and the other is black.
Just connect it to either of the two fan connectors located around the battery on your motherboard.
Some fan headers like the PWR_FAN or SYS_FAN allow RPM monitoring...Some do not...Just depends on your paticular motherboard and the specific fan header you use...It usually states in the manual if the fan header supports RPM monitioring.

Yes your 380watt Antec TruePower power supply will adjust the speed of the two 80m/m fans inside your power supply according to system temperatures.
Further more any fans that you have connected to the "Fan Only" 4 pin molex connectors will also be adjusted according to system temperatures.
Experiment using the "Fan Only" or standard molex connectors for your case fan or fans which ever may be the case.

yes, the wire is black and blue
so my 380 watt PSU has 2 80 mm fans inside your power supply.
so i can attach the case fans to the regular 4 wire molexes or the case fan labelled molexes, with the case fan molexes i will get temperature regulated operations and with the the regular i will not. is my understanding correct?

Yes you are correct.
With THESE four pin molex connectors...Your 380watt TruePower will vary the voltage to your case fans depending on system temperatures...They are to be used only with fans.
The standard molex connectors will run your fans at 12 volts all the time.
If you do not mind me asking is noise an issue and what heatsink and fan combination are you using ???

noise is not really an issue
i am a newbie migrating his components from an old case to an antec sonata.
i got 2 120 mm fans(the fan that came with the sonata) and a second antec fan (with a 4 pin molex with 2 wires connected and a 3 pin connector with one wire connected)

Another consideration is that Antec specifically states not to install theramlly controlled fans on the "Fan Only" molex connectors.
Can you link me to the other fan you are talking about ???
If it is indeed a "SmartFan" you will want to connect it to a standard molex connector...Not the "Fan Only" molex connectors.

Depending upon your motherboard, plugging in the fan monitor for the PSU could cause some issues if your motherboard has any sort of temperature-based fan speed control. I have my wife's PC in a Sonata case and I plugged the PSU fan monitor cable into one of the fan headers on the computer's Intel 915PBL motherboard and I had all sorts of trouble with Intel's Desktop Control Center software crashing until I unplugged the cable. I even had an issue where I would get a lock up when exiting the BIOS if I went into the hardware monitoring options.
My pet theory is that the problem boiled down to the fact that the BIOS was reading the fan speed of the PSU and trying to vary the fan speed accoriding to its own onboard temperature sensors without knowing that it had no capability to change the speed of the fan (which was actually being controlled by the temperature sensors in the PSU) and the BIOS got utterly confused. I don't know for sure if that was the true cause of the issues I ran into, but it kinda makes sense. So if you start seeing any weird hardware monitoring issues with the PSU monitor plugged in, then you might want to unplug it.

my fan is a Antec Smart Cool 120mm Fan
i guess the solution would be (attach the 120 mm fan which came along with the case to the 2 wire fan only molex connector, not connect the 3 pin connector of the PSU to the mobo since it would mess up the BIOS
attach the second optional smart antec fan to a normal 4 pin molex connector and attach this one to the fan SYS_FAN connector on the mobo

Just to clarify, the Sonata PSU is a single fan PSU.
Doesn't really matter for what you are asking, just didn't want you wondering where the second fan is hiding.
