This guide also works for older versions of the Pentium M processor type we use in this guide Notebook Hardware Control (NHC). This software is freeware.
Prior :
A processor running at a certain voltage and then produces heat which causes the fan.
The latest Intel inside (Pentium M and Core 2 Duo up to lately) are able to vary their voltage according to the activity. So there are different multipliers for different voltages. The lowest is consistently used when the CPU usage is minimal and the highest when the CPU is loaded up. There are of course a set of multipliers intermediaries. If we can lower the voltage assigned to each multiplier, the CPU should logically less heat. Indeed, to perform the same operations the processor will use less power. Similarly, if the voltage is lower, the processor speed remains the same. This observation in mind: what could be the negative consequences of such an operation? Primarily the system instability. The question is therefore whether the processor is sufficiently stable once the frequencies lowered. There are several ways to test it. The NHC allows software to a basic test after each adjustment, which allows to highlight the large instabilities. In sum, if such a test when you get a fatal error or blue screen, it should increase a bit frequency.
Results :
Note that in my situation handling and testing on different machines at low frequency (first frequency multiplier and approximate) I have no problems. I cons by, and this is the expected result, won 13-20 degree in the settings of origins. Thus on an HP nw8440 release more than 75 degrees with the settings origins after fifteen minutes of a game requiring (note that the graphics card plays a role in temperature in this case) the temperature drops to around 60 degrees. You can also use specialized utilities that test your setup and pushing up your processor to test its effects (stress test).
