Asus Q-Fan and Zalman 7000B CPU coolers.

[Zucarita9000]

From Asus:

Q-Fan Technology
This unique technology intelligently and automatically adjusts CPU fan speeds according to system load and temperature, enabling users to work in a distraction-free environment with minimal noise.

I know that the Zalman comes with the Fanmate 2 controller to control the speed, but what if I plug it direclty to the motherboard and let Q-Fan asjust the speed? Would that work?

I dunno about Q-Fan personally. I plugged my Zalman into the mobo, sans the Fanmate, and let the Zalman run at full speed all the time. Its amazingly quiet even at full speed, so I haven't bothered trying to slow it down.

Yes it will work, and it's a much better method in my opinion.

I see. I've just enabled Q-Fan on my brother's PC and there is a difference. The fan is spinning around 1000rpm less, wich of course eliminates some of the noise. The rig is using stock cooling for it's P4 cpu.

So, basically what does Q-Fan do? lower the voltage?

I'm pretty sure it uses PWM (Pulse Width Modulation), rather then actually changing the voltage.

Right now I'm using SpeedFan and have both my CPU and case (exhaust) fans thermally controlled. CPU temp is set at 50C and case temp is set at 35C, it's dead silent at idle and gives me extra cooling when needed.

i wondered this too, so its ok jus to forget the fanmate, (its cluttering my wiring) i run it on its lowest setting all the time....it cools perfectly, but the qfan thing i would like to use....do i jus plug it straight to the mobo and enable Q-Fan?

Looks like it... Q-Fan seems to be doing a great job. The noise has gone down considerably.

i just purchased the zalman cnps7700 cpu fan (which is huge) i have the asus k8n-e deluxe and am wondering the same thing, i don't think this mobo uses q-fan, i think it's called smartfan or somesuch thing.

Yes, it has the Q-Fan 2. Look for it in the BIOS

I've seen Q-Fan melt the plastic off a stock AMD cooler on a 2800+ Man was that a mess.

Are you serious? After enablign Q-Fan the noise has gone down considerably and te temperature only increased about 4º. Not too bad. I really doubt that that would melt the platic of the fan. The rig now idles at about 38-41º with the fan spinning at an average speed of 2200RPM. Before that, it was at almost 4000RPM and really loud.
