Keep fan settnings, and power supply question

[Frejoh466]

Hello everyone,

I did just buy 2 new fan's http://www.xigmatek.com/product/accessory-xsff1251.php I installed them and powered up my computer, 10 seconds it had load the desktop my computer did suddenly restart, then I thought it was a power supply error so I removed one fan and restart the computer and now it's run fine, I think.

Whit SpeedFan I lowered the fan speed whit 30% and now I'm wondering 2 things, if I can keep the fan speed on start-up somehow and if it really is a power problem, tho it seems like it I just want to be sure.

System speck

Processor:    Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz (2 CPUs)
Memory:    2496MB RAM
Hard Drive:    1550 GB
Video Card:    NVIDIA GeForce 9800 GTX/9800 GTX+
Monitor:    1680 x 1050
Sound Card:    SoundMAX HD Audio
Keyboard:    HID-Compliant Bluetooth Keyboard
Mouse:       HID-compliant Bluetooth Mouse

and I did clean my computer when I installed the fan's, and I got a 700W power supply, and can I see if I have enough power to keep everything working?

Post your temps...

Who makes this PSU ? ?

[Frejoh466]

Here is the temp

this is when idle not when I play games, and the fan's I bought are not on. I also have a regular fan in front of the computer (300x300)


and you have to define

Who makes this PSU ? ?

or do you mean manufacture? then it should be cooler master, other wise you have to define it.

Edit:
what if I use a 3 pin connector and plug it in to a 4pin,


then connect it to the Power supply thingy, would it be any different from plugging it in to the mother board,


Or would the power be the same even if I plug it in to the 4pin direct to the power supply


Or will everything be a mess?

Edit2:
Fixed some picture

Edit3:
Feel free to help if you feel like it, I'm open minded.

I still cannot decide what your goal here is...
And i've read the thread 3 times...

All I can understand is that he added 2 fans and the computer shut down a short time after the desktop loaded.  He removed 1 fan and the problem has not reoccurred.
I don't think a 700W psu will have an issue with multiple cooling fans.  I suspect the 1 fan was connected incorrectly since he doesn't seem to understand what signal/voltage is on what pin.

Computer_Commando are right but well you get the fan's whit a 3pin connector I plugged both in to the only 3pin I had on my computer,



and then the fan's have power supply, but my motherboard didn't give enough whit power so the computer did a "emergency" restart, so I removed one fan and started my computer and it run, but I don't know if everything else will get enough power so I was asking if I could connect the 3pin from the fan to a 4pin so I could have direct connection to the power supply.


I use a 3 pin connector from the fan and plug it in to a 4pin,


Then connect it to the Power supply to the 4pin, you see the a text saying Molex 4 pin etc there is where I connect it


Would that work?

Btw it's ASUS P5B motherboard

...I was asking if I could connect the 3pin from the fan to a 4pin so I could have direct connection to the power supply...

Yes, but only 2 of the 3 wires can be connected, +12V & Gnd
On the 4-pin molex:  +12 is yellow, Gnd is Black (2 of them), +5 is Red
On the fan:  +12, Gnd, Speed Sensor (rpm); one of the reds is +12, don't know which.
You should be able to connect the fan directly to the motherboard, if you know which wire is which and what pin is what.
On motherboard pic, from right to left, pins are:  Gnd, +12, RPM_Sense, but you should check this with manual or voltmeter.

My motherboard can't give enough whit power to both of the fans, so everything just die if I connect them to the motherboard.

Edit:
Well now the fan dose take power directly without any crash and burns, but now I can't control speed due to it's not connected to the motherboard, well I guess I can live whit that if I don't want to do some serious hacking. but thanks for the help

Speed control is what the 3rd lead is for...

Speed control is what the 3rd lead is for...

So if I plug the 3rd pin in to the motherboard I get speed control. Thanks patio

Yepper...

Nope.  Speed sensing, not speed control.

Common cooling fans will have either two, three, or four pins on the connector.

Two-pin fans operate either as an on/off fan, or can be controlled by varying the voltage.
Three-pin fans add a tachometer reporting wire so the controlling system can measure the actual speed.
Four-pin fans add a fourth wire to control fan speed using PWM (Pulse-width modulation.)

Yer kiddin me right ? ?
If there's no speed control then what wire would control that ? ?

Can't wait for this response...
