RPM Control??? on the PSU

Hi

I am in the middle of building my first ever pc. Be Quiet darp pro 650 has a rpm control connector (which I believe regulates the fan on the psu).

Where do I connect this on the mobo??? I have an msi 790fx mobo.

Thanks for your help

Are you saying that you have 2 connections from the CPU fan? If it's only one than it should be connected to the pins marked CPU fan (refer to your mobo manual) If it has an additional connector (as I suspect) then I'm at a bit of a loss as to where you would connect it....You could try it on a spare fan connection on the board (usually system fan, aux fan etc.) But I'm not sure if that would show up in the BIOS as the cpu RPM controller.

If all else fails, contact the company and ask them...It may be that your board will not support the extra connection.

AMD CPU's have "Cool and quiet" built in, but it's just one connection.

On the MSI 790FX-GD70 Series motherboard their is 5-fan connection that can be used as

follows: -


CPU Fan – CPU


SYS Fan 1 – Memory Chips Fan

“CORSAIR CMXAF1 FAN”

SYS Fan 2 – Hard Drive Fan

Scythe Ita Kaze Hard Drive Cooler

SYS Fan 3 - Power Supply Fan


SYS Fan 4 – Case Fan

Well spotted, I'm not familiar with the board in question, but thought there was probably a way....That cpu cooler / fan assembly has 2 connectors then, or just the one five pin (for future reference) :))

looking at the PSU it goes into a 3 pin on the motherboard and is connected and run via the BIOS

No there are 5 separate fans connectors on the motherboard listed as above

No, I meant on the CPU / cooler assembly itself?

The Be Quiet 650 has an automated self regulated fan. The 4 connectors on the power supply are to connect case fans.

I believe you have it wrong

The “Be Quiet Dark Pro 650 Power Supply Unit” has a special connector that you can connect

to one of motherboard fan connector and would control the speed of the power supply fan

1 x 24 Pin Motherboard Connector with Adaptor to 20 Pin

1 x RPM Control (3pin)

The CPU connector on the motherboard is a 4-pin connector that will also allow a normal 3-pin

CPU fan to be connected

Yep, thought that's how it was...Noted for future :))

The RPM control cable does not control the fan, it's a sensor that will report the speed only. It can be plugged into the motherboard and something like HWMonitor click here will report the speed.
