CPU cooler advice for P5E3 Premium
I'm about to upgrade my CPU to a Q9550 and want to buy another cooler
for the cpu, I want to be able to have the option so that when pc is idling the fan will slow down to cut noise yet when i do heavy intensive cpu work it will of course spin up to a higher rpm. I'm unsure how this works though do i have to install some kind of 3rd party app from Asus or someone else, is it controlled in the bios, if it's a windows app what happens when i'm outside windows for example making an image as i say outside windows.

Jim Look under the BIOS menus for Hardware Monitor and set the "CPU Fan Control" item to "Profile". Once you do this, an new item becomes available, "Fan Profile". Set this to "Optimal" for completely automatic CPU fan speed control. This is OS independent. Also check whether you need a BIOS upgrade before fitting the Q9550 - looks like you need version 505 or later for that CPU. HTH -- Rob |

HTH OK thanks for that Rob I have the latest bios (0803) and i think my new cpu will work in there ok, mine is a "Intel Core 2 Quad Processor Q9550 SLB8V 2.83GHz E0 12M 1333" so i'll go into my bios now and set the settings JIm |

Jim The only other thing I'd add to Robs answer, is try to get a CPU cooler with a four pin fan. To match your four pin CPU header. While they make three pin CPU coolers, you may not necessarily get a speed control feature by doing that. The four pin header helps in that respect (PWM control pin).

Jim So electrically, what you'd want, is something that translates four pin PWM 25KHz signal, into three pin analog +12V. Example here. http://www.svc.com/pwmx.html "The Nanoxia 3-Pin to 4-Pin PWM fan controller is a unique adapter that allows you to plug any standard 3-Pin fan into your PWM motherboard and have your motherboard control your standard fan as if it were a PWM fan!" Effectively, that would be using the circuit that comes inside the hub of a four wire cpu fan. They're asking $13 for it, but it would be cheaper than that, to make it. The inside of it, is pretty cheesy looking. http://ts3.mm.bing.net/th?id=H.50335...29130&pid=15.1 This thread here, addresses the general topic. If I'm reading this right, the Nanoxia "quantizes" the fan speed setting. The motherboard sends a continuously variable fan speed signal, but the Nanoxia chooses to send out 5.1, 6.7, 8.0, 9.3, or 10.4 volts (never goes to 12V, due to the drop across the pass transistor). http://www.eevblog.com/forum/project...converter/105/ Whereas this kind of design, is continuously variable, just like the motherboard. http://www.compendiumarcana.com/pcfa...adjustable.png I expect both designs, will be kicking out a bit of heat while they do the conversion. So it is possible to do conversion, if you're sufficiently motivated to track down a good design. That preserves all the design intent, of the 4 pin, but with a 3 pin interface. Paul |

So it is possible to do conversion, if you're sufficiently motivated to track down a good design. That preserves all the design intent, of the 4 pin, but with a 3 pin interface. Can't 3 pin fans be controlled by the bios/motherboard? I do that on one of mine. There are two generations of control methods. But they both boil down to the same thing. Just slight differences as to where the conversion is done. On a three pin fan, you want to vary the +12V supply voltage to the fan. The three pin fan, generally the fan is "just a DC motor", so changing the voltage makes some difference to the speed. Your motherboard, would have a transistor of some sort, next to the three pin CPU fan header. The signal coming to that transistor is PWM, because a PWM method saturates the transistor, keeping power dissipation in the transistor low. You could easily use other, non-PWM methods to create a voltage, but those are less common as a methodology. (I use diodes to drop voltage here, and have also on occasion used a 78xx family regulator for reducing fan speed.) Now, on the four pin fan header, Intel says you're supposed to keep the 12V pin at precisely 12V. They say that, because they know there is a transistor inside the fan hub, and it works best running at 12V. If you feed a reduced voltage to the fan, at the same time as you also feed it a PWM signal instructing the fan to slow down, the transistor doesn't get biased properly. The hub of the fan starts to get warm, or hot. So with the four pin interface, the fan gets a constant +12V source, as well as the PWM logic signal. The signal runs at 25KHz, the intent being, any acoustic noise made as a byproduct of that signal, is above human hearing. The PWM signal works the same way as the old three pin, motherboard-centric solution would have worked. The PWM signal operates on a saturated transistor inside the fan hub, and the output voltage from that operation, feeds the fan motor. So all Intel really did, was push the expense of that transistor, to the fan manufacturer, and away from the motherboard manufacturer. There were some "transition" motherboards, where the four pin fan header supported both methods. But the user was responsible for setting a control in the BIOS properly. The user had to set it to "three pin", when a three pin fan was present (so the +12V gets dialed down). Then, if a four pin fan is being used, the user has to remember to change the BIOS setting as well, to PWM. Then, control is purely via the PWM logic signal, and the +12V from the motherboard, stays at a constant 12V level. There were a fair number of boards with that option, so you may still run into some. The user in that case, is responsible for not setting the BIOS to "three pin mode", when a four pin fan is present (as Intel wants the 4 pin 12V pin, to run at 12V). Paul |
