AMD Cool "n" Quiet - Good or Bad
I would like to know if the Cool "n" Quite feature offered by the Athlon64
and the used with the K8VSE Deluxe motherbard is any good. Will I take a performance hit using it? I am using a Althon64 3200 with 1G mem and Win XP Pro. TIA |

I am using a Althon64 3200 with 1G mem and Win XP Pro. I turned on the cool-n-quiet on my k8v-se-d just for grins. After saving the settings for cool-n-quiet, I returned to the bios setup and watched the temperatures and fan RPM via the hardware monitor page. Over the course of a minute of two the bios slowly turned the CPU fan's RPM down lower and lower till the fan finally stopped. The CPU temperature naturally sky-rocketed well past 50 degrees C. I quickly turned the cool-n-quiet off, saved the settings and then entered the bios again to watch the temperature drop to normal levels. Something is clearly wrong with their BIOS software. If you turn it on I'd be very careful and watch that it doesn't misbehave. You don't want to fry an expensive CPU. -wolfgang -- Wolfgang S. Rupprecht http://www.wsrcc.com/wolfgang/ |

Cool 'n Quiet is running without any problems. The CPU fan only runs when needed. When CPU temperature rises to about 52 degrees Celsius, CPU fan starts running and stops, when CPU temperature goes down to about 46 degrees (shown by Asus Probe). Siegfried |

Hi Johnny,
C"n"Q works perfectly for me. I have exactly the same MB/cpu/memory as yourself. When not gaming (UT2004) it kicks in unoticeably. At the moment it's running at 1000mhz, voltage 1.074. ASUS probe gives me a cpu of 27degrees, mb 24degrees, this with an ambient temperature of 21degrees. When online gaming C"n"Q quits giving exellent performance. UT2004 gives me 100+fps with all settings maxed out. CPU temps rise to 40-43 degrees, mb possibly 30degrees. When C"n"Q does kick in there is no noticeable drop in performance. All day to day operations still appear to be instantaneous and I have to click the icon to see it is in fact in operation. Since building I have flashed the bios to 1002.006 dated 4/14/2004. Cool "n" Quiet is, for me, the best thing since CSI (get'em Grissom). HTH Dave "Johnny B." wrote in message . net...

Yes, the temperature does rise up to about 52C before the fans cut in - It
scared me a bit when I first tried it. But providing it does not go higher - i.e. C&Q is working, then everything should be reliable. If you don't like the idea of the fans not cutting in until 52C or so, then simply disable the Q-Fan thingy and let the fan run continuously. This should make the CPU temperature plummet downwards during idle. I have not noticed any performance degradation with C&Q, although I suspect that there probably is a tiny bit when you first start a demanding program and ithe ciruits have to "ramp up" to full voltage and speed. I particularly like the fact that the power is reduced so much during C&Q operation - This should improve the reliability of the power supply circuits on the motherboard as well as the ATX Power Supply. - Steve "Johnny B." wrote in message . net...

Yes - that's certainly a valid way of looking at it, Ben!
But bearing in mind that semiconductor reliability decreases exponentially with temperature - and also the fact that my own system stabilises nicely in the "cool" mode most of the time the way I use it - I think that I prefer to use the C&Q rather than not. The variation in temperature of the power supply components is reduced if it incorporates a temperature controlled fan. Another point is that most of the failures I have experienced with PCs are related to fan failure, particularly smaller ones like chipset or CPU fans. They go noisy then seize up. I therefore like the idea of running the CPU fan only occasionally, which is what happens in my own system. On the other hand, I used to set my system to spin down it's hard drives whenever they had not been used for a while. I have stopped doing this, as I get the feeling that regular contact start/stop cycles are probably more detrimental than leaving the fluid bearings spinning... - Steve "Ben Pope" wrote in message ...

But bearing in mind that semiconductor reliability decreases exponentially with temperature - and also the fact that my own system stabilises nicely in the "cool" mode most of the time the way I use it - I think that I prefer to use the C&Q rather than not. Indeed... I was thinking more along the lines of the discrete components like capacitors - especially on the CPU voltage regulation side of things. The variation in temperature of the power supply components is reduced if it incorporates a temperature controlled fan. Another point is that most of the failures I have experienced with PCs are related to fan failure, particularly smaller ones like chipset or CPU fans. They go noisy then seize up.

I have stopped doing this, as I get the feeling that regular contact start/stop cycles are probably more detrimental than leaving the fluid bearings spinning... The specs usually say how many start/stop cycles the drive can handle... It is true that spinning hard drives up is one of the most strenuous activities the drive can do, leaving them running is not a bad idea.
