Fan Speed Controller Problems

[KugarWeb]

Hi there,

I recently replaced my Fan Speed Controller as the old one failed. Unfortunately, the Fan Control Box (which connects inbetween the CPU Fan and the Controller itself and "talks" to the Motherboard) that came with my Gigabyte GForce Cooler isn't compatible with the connections of my current controller and so there is no connection with the Motherboard to transfer information regarding the CPU Fan's speed.

This has meant that upon bootup, a continuous beep can be heard after the POST screen and a quick check in the BIOS confirms that the CPU Fan is apparently running at 0RPM, even though it is working perfectly and all temperatures agree with the previous setup. However, when plugging the CPU Fan directly into the motherboard (thus meaning no control over it's speed), the fan is recorded as running at around 3300RPM.

Is there a separate control box I can buy which can tell the Motherboard what speed it is running at or is this only bundled with CPU Fans?

Cheers,

Hi there,

To help with this problem further, below is a picture of my current Fan Speed Controller and it's connections.

You can disable the cpu fan fail warning in the bios. The only way you're going to get motherboard monitoring of the cpu fan is if it's connected to the CPU_FAN header on the motherboard, not a fan controller.

You may be able to adjust the settings in the bios, for cpu fan speed control. Asus boards have what they call Q-fan, you can set the cpu fan speed to silent, normal, or performance. Other brands of retail boards have something similar.

The gigabyte controller was probably a single in-line controller, which draws it's power from the motherboard header, but, since it's in-line, it can slow it down and speed it up.
Something like the Zalman Fan Mate 2 will do that, but not in conjunction with the 4 channel controller pictured above, it'll do it all by itself.
