AMD Cool & Quiet

I have AMD Cool & quiet installed but i'm not sure if it's working properly. I followed the instructions and enabled it in the BIOS, and then in windows power management by selecting minimum power management. But the noise is still the same. It also said to enable ACPI 2.0 in BIOS in boot menu, but I only had an option for ACPI APIC. My PSU is a Thermaltake 680W and it's always loud, even after enabling cool & quiet. My mobo is an Asus A8N Slu Deluxe. How do I know if I have this installed correctly?

There is a special header on your mobo for psu fans. Are you using it? That is what would control the psu fan. If you are not pluged in, your psu fan will default to full speed.
I dont plug in, because the psu fan is very good at keeping system temps down.

even if i had it plugged in, i don't have to enable cool & quiet all the time so i can still operate at full speed right? anyway, do you know where this connector is located?

It's just behind the bottom of the backplate, above the top left hand corner of the top PCI- exp slot. The printing is small, but it is labeled "pwr fan".
FYI, C&Q will allow your chip to run at full speed on demand.
The psu fanspeed control will work, wether C&Q is enabled or not.

Do you know what Q-Fan is? It it currently disabled in the bios, should I enable it?

Honestly I've found AMD Cool and Quiet to be fairly annoying. It randomly locks up my system when I go from low load to high load (voltage probably doesn't increase quick enough or something) and so I've just turned it off.

But that's beside the point. Take a look and see if your CPU fan is throttling down. It may be that your PSU fan is louder than the CPU fan in the first place.

I don't know if I understood correctly... but it sounded to me like you were upset with the "overall" noise of your system. And you know that the 680W PSU is making a ton of noise. I just wanted to make sure that you know C&Q will not decrease the amount of noise coming from the PSU at all, so if the CPU fan noise is negligible in comparison to the PSU noise, you may not notice much of a difference at all.

well the sound i'm hearing is probably coming from my psu fan. but isn't c&q suppose to make it less noisy because it's decreasing the overall voltage? Also, do you know what Q-fan is? I have an option for it in the bios but it's set to disabled.

The ASUS Q-Fan is a fan regulation thingy that spins the fans down to a lower ratio depending on what you set it to when temps are low. It's defintiely something you can use if you're trying to lower noise levels.

Q-fan can be used to control certain fans. You do get a list, when it's enabled. Please enable it, and then check to see if the psu fan is controlable, through it.
AFAIK the psu has monitoring capability, but just needs the mobo connection to work.

C&Q will decrease the sound coming from the CPU fan when it decides that the extra cooling is not necessary. However, C&Q does not throttle down the PSU fan. So if the PSU fan is causing all the noise then you have to fix this via other means. One suggestion would be to do what Wusy suggested and get a fan controller. I am shocked that the Thermaltake 680W didn't come with a controller... in fact, I'm kind of disappointed with that. I just looked it up, and for some reason they package a 480W with 2 controlers (for front and back of case) and ZERO controllers with the 680W... does this seem strange to anyone else? For the extra $100 bucks I would have thought they could throw in that 3 dollar part.

Read 2.0.3 from my GA-K8NF-9 FAQ :
<A HREF="http://forumz.tomshardware.com/hardware/modules.php?nam..." target="_new">http://forumz.tomshardware.com/hardware/modules.php?nam...;/A>

It explains all the step to make C&Q working, I personnaly used it succesfully for a couple of weeks. Stopped using it because my PC is shut down most of the time now.

I think that the C&Q might very well be working... I think he just expects it to do something more than it does.

Yup! When I used it, I noticed no big difference, since 90nm AMD chips are not that HOT. It would be great to have a systray icon or a Casing LED that would inform of current C&Q status. This could be good for Intel based system too. I used the AMD C7Q Dashboard, but it takes a lot of place and it is ugly.
