Hey,

just thought i'd post to see what your opinions are on this subject,

I have MSI's cool & quiet installed and was using it to take car of my CPU (AMD Athlon 64 3000+) and motherboard fan's

However, a while ago the alarm started to sound because the rpm's were dropping below the set alarm level. So i switched to user mode and stook the fans at 6/8 speed (moves the fans at about 2909 rpm)

Im just wondering what your opinions are about this situation?

The fan's are pretty noisy in user mode and if i put it into cool & quiet mode im scared of leaving my computer incase the rpm dropps and the fans can't handle the heat as well, ultimatley frying my machine!

Any info would be apprechiated,

Regards.

Chris. :)

p.s. the specs of my machine are in my sig :)
 
I have almost the same set up you do except that I have a 3500+ and have been running with Cool & Quiet enabled since about day 2 with no problems at all. It will let the fans spin pretty slow, but so long as things are keeping cool, who cares what the rpm is actually at. I would disable the alarm or lower the alarm rpm personally. As long as when the system starts to heat up the fans spin up, I actually would care less if the fans even stopped at some point.

Anyway, short story, C&Q hasn't let me down yet (been almost a year now) and it definately helps keep things quiet. I would guess its probably just your fan rpm alarm settings that are set too high. I'd just keep a temp monitor going if you want to be sure things are working right.
 
Well, if it helps, Cool-n-Quiet doesn't actually controll the fans directly.

What Cool-n-Quiet does is use the feature built into the AMD CPU to downclock the frequency and reduce the voltage. My 3000+ drops to 1.1 volts and 1GHz when Cool-n-Quiet is in operation.

When the AMD Processor driver detects that you are increasing utilization of the processor, it ramps it back to full speed and voltage. Cool-n-Quiet is not "extreme" overclocking friendly however, and should be disabled when OCing. Reason? It returns the CPU to the default multipliers (x9 on the 3000+), so if you had your multipliers reduced with a high frequency, it'll return to the high frequency but use the default multipliers and possibly exeed the ratings resulting in a blue screen or other type of crash.

That said, I use Cool-n-Quiet and like it. The fan speeds drop because the motherboard (CoreCell chipset) detects that the temps have dropped a lot and it slows down the fans. The fan speeds will increase on increase in temps, so I wouldn't worry about it toasting your system.

Your only concern is if you are doing "extreme overclocking" because of the return to "default" multipliers that you may reduced to achieve high frequencies. Dynamic Overclocking works with the CoreCell and Cool-n-Quiet technologies and uses the default multipliers, so this won't have the same multiplier problem as a manual over clock would.

Here's a couple links with more details:

Yes, Cool 'n Quiet does do all the above. But there is still a feature, whether it be AMD's or MSI's or some hobo's responsibility, that controls the fan speed in accordance with temperatures (that would be the Q part of CnQ). Despite everything said in the last post, the OP's problem still remains.

And I would do like Fusoya said and lower the alarm setting, but watch temps. If your CPU temp doesn't go above 55 or so degrees Celsius, you're fine.
 
thanks for the fast replys guys!

I think im gonna enable cool & quiet again and see how it goes from there.

At the moment the ambient temperature of my system stands at about 36C, after doing processor intensive stuff like photoshop, playing games etc it can creep up to between 40C and 48C,

My CPU's adverage temp is anything between 35C on a cool day (of which we have many in the UK ;) ) and 40-45C after performing processor-intensive tasks, playing games etc.. and when we have a warmer day (say around 25C)

Are these temperatures normal? this computer is a pretty recent build for me, a major upgrade from a stone-age system, so im not sure what the temperatures should be on the high-performance systems of today. for example, i was blown away at the fact that my graphics card has a core slowdown threshold of 145C! lol (call me old school but my graphics card before this one was a nVidia TNT2 32MB AGP one :D lol

anyways, thanks again for the info, much apprechiated :)

Regards,

Chris. :)

EDIT:

Forgot to mention, I don't overclock my system so thats not a factor. The nearest thing i have done to overclocking is upgraded my bios using the MSI Live update feature lol.

Thanks,

Chris.
