I have a Zalman 9500 HSF with manual controller.
In BIOS there is a setting for smart fan and the auto fan controller.
Since it is manually adjustable, should I disable these?
When I booted the comp for the first time today, it beeped several times consistently even though it loaded fine.
fan is working and core and board temps are normal.
Thought there might be a conflict.

I have the same fan, I typically just throw the manual control out with the trash as they are doohickies for people who like knobs ...

The auto fan control will spin up or spin down the fan based on a predetermined algorithm for maintaining a constant temperature, it of course allows for quieter operation during idle time but I normally disable this feature anyway.

As you already have a regulator inline with the fan, you should probably disable the fan control on the MB, however it does no harm since the scheme will attempt to drive the fan to maximum when it is needed and will be limited by your manual set point anyway.

My personal recommendation, the 9500 runs quiet enough. Take out the manual doohicky, turn off the auto fan control and go from there.

JackYou learn something new every day. For instance, i didn't realize that doohicky was a term used by the scientific community.

Word.

The Zalman MFC-1 fan controller is nice if you like total control over each fan in the system

I currently have a zalman 9500-AT, zalman vf900-cu, and four armor case fans (12v/off/5v) connected to it, and let me tell you, it's sweet

If you prefer, I could implement the use of thingamabob.

What about.... Whatchamacallit?

I just ordered the Zalman fan controller. I have really only three fans (2 exhaust that run through the system fan pin connector and the CPU fan.
The front intake fan is on a 4 pin molex and spins at a constant speed. It is a 3 pin with adaptor so I suppose I could just get an extension and run the front fan off of the fasn controller also.
Thanks for the advice on the fan mate. I noted on start up a conflict. I disabled the auto fan controller in BIOS. My case is big and the Zalman and the 2 AC 120mm exhaust fans are really quit even at high speed. As such I usu leave the Zalman on its higher setting.
