I opened my cpu fan today for dusting, but after that onward my cpu is running at max speed always, the cool n quiet feature is not working like it used to.

What do you mean you "opened my cpu fan today for dusting"? How do you open a fan & how did you go about dusting it? More than likely you disturbed the CPU heatsink. It's no longer seated properly & now the CPU is running hot.

yeah the metal heatsink and the plastic fan attached to it.
I turned the lever took out the heatsink dusted it using a brush, applied fresh thermal paste, then fixed it back again above the cpu. Everything is running fine expect the core speed.

Did you clean off all the old paste & then apply just a tiny dab in the center of the CPU? Like THIS? Have you checked the CPU temp?

"Everything is running fine expect the core speed"

Cool'n'Quiet adjusts the core speed based on load. If you want the CPU to run at full speed at all times (even at idle), disable Cool'n'Quiet.

yeah i cleaned off the old thermal paste but i think i might have applied a bit more than than the picture suggested.
Cool n Quite is enabled in my Bios but my cpu is running at max speed always even at idle(according to cpuZ), and its running hot as well around 65C even at idle.
I dont want my cpu to run at max even when there is no load.

Here is the A88GMV User Manual:

http://www.produktinfo.conrad.com/d...

Look on page 16.

I think it has something to do with the 4 pin cpu fan header on my mobo, And is it okay to connect the 4 pin cpu fan power cable to the NB_FAN header on the mobo?

"around 65C even at idle"

Probably because you applied the thermal paste incorrectly. Was it running that hot before you messed with it? Remove the heatsink & try again using the 'middle dot method'.

"is it okay to connect the 4 pin cpu fan power cable to the NB_FAN header"

No. Why would you do that? Is there some reason why you're not using the CPU_FAN header?

yeah I tried the middle dot method, but cpu still running at max and HOT.
And NO it never ran so hot at idle before, at idle temp would vary from 50-54 C.
but my problem is not coz the CPU is getting HOT, its coz the CPU is running at MAX SPEED ALWAYS (CORE SPEED: 3200 MHz, MULTIPLIER: X16), MOST PROBABLY THE COOL AND QUIET FEATURE HAS STOPPED WORKING.

The reason I want to connect the cpu fan to NB_FAN header is coz I think the cpu fan header is malfunctioning, and is the reason the why the cool n quiet feature is not working(just a wild guess).

What do u think?

"NO it never ran so hot at idle before, at idle temp would vary from 50-54 C"

Even that is way too high. If the temp readings are accurate (are you getting them from the BIOS?), the only thing that could possibly be wrong is the heatsink installation. Either you used too much paste, not enough, applied it incorrectly, or the heatsink isn't seated properly. My overclocked Phenom II X3 idles in the low 30's.

okay I get all that, but why is my cpu running at max clock speed always?

oh and I made a mistake in my last post, at Idle my cpu temp varies from 40-45 C.

Did you have this problem with Cool'n'Quiet before you messed with the heatsink? Have you made any software changes or changes to your power settings? Cool'n'Quiet must be enabled in the BIOS & the power setting must be set to either Balanced or Power Saver mode. If you have it set to Performance mode, Cool'n'Quiet is disabled.

EDIT: I assume you're running Win7. If you're running XP, the Cool'n'Quiet driver has to be installed. Win7 natively supports it so no driver is required.

EDIT 2: Have a look at this: http://forums.legitreviews.com/abou... - I disagree with the 2nd point under "DO NOT". I have my CPU settings manually configured & Cool'n'Quiet works as it should. If you're not overclocking, you could try the CPU settings on Auto rather than Manual & see if that makes a difference. But who would buy a Black Edition CPU & NOT overclock it? Isn't that the whole point of BE CPUs? ;-)

"* For optimal power savings, be sure to also enable C1E and DRAM Power Down in the BIOS"

yeah c1e is enabled but what does the second part mean DRAM Down thing?
