Dear Sirs,

I have obtained a newer motherboard AsRock G41MH/USB3 R2.0, but have a quick question before putting it all together and powering it up..

Current Specs:

1x Weston Digital 1TB sata drive,
1x Intel 775 2Quad Q6700 2.66Mhz
1x Powercool 850 Watt 80+ PSU
2x 4GB DDR3 RAM
1x PCIe 5 USB v3.0 Ports
1x 3.5" Floppy and Multi Card Reader Combo
2x DVD RW's

I have a 14" Intake fan (4-pin), 92mm Exhaust fan (4-pin), and the CPU fan (3-pin)

Here's the link for the 'mobo': http://www.asrock.com/mb/Intel/G41MHUSB3%20R2.0/?cat=Sp...

And, here's a link to the mobo manual: ftp://europe.asrock.com/manual/G41MHUSB3%20R2.0.pdf

Page 11 of the 'pdf' file shows the 'mobo' diagram, which leads me to my question...

Please can a GURU advise me if I could use the Power Fan Connector (PWR_FAN1), for the CPU fan as they are both 3-pin as then I could control all fans via the software it come with and possibly SpeedFan.

Thank you in advance of reading my thread and posting a reply.

Regards, Jonathan

You shpuld connect the cooler to the CPU fan connector, because if you don't then the PC will think you don't have the CPU cooler, the PC will not pass the POST ( Power-on self-test ) and will not boot.

Dear Night Owl,

Thank you for your reply.

Just to clarify if I may, although the three fan points on the motherboard will used but in a different way (see below), it still will not work?

1. Chassis Fan Connector (CHA_FAN1) 4-pin= Exhaust 4-pin Fan

2. Power Fan Connector (PWR_FAN1) 3-pin = CPU 3-pin Heatsink/Fan

3. CPU Fan Connector (CPU_FAN1) 4-pin = Intake 4-pin Fan

If your initial answer still remains, then how as I will lose the Intake Fan's 4th pin (is it PWM?) how can I control the fan speeds, or set them automatically?

Hope you shortly advise me again, thank you.

Regards, Jonathan

You can try that, but most MB can only use either PWM ( for 4pin) or by voltage ( for 3pin ), or auto. You can go to BIOS to set voltage OR PWM.

*I know what you mean. You can't put either 92mm or 140mm fan into the 3 pin connector on the MB. So you can try this: cooler and 92mm fan into the MB, go to BIOS set up option by the voltage control the fans. Connect the 140mm fan into the PSU using the adapter comes with the fan.
