What is the difference between Windows 7 system power management and the past?

Whether it is using win7 or other systems, as long as the notebook will use power management, but the power management of win7 itself has made progress, most of them have improved the temperature problem. These days, I have been discussing the heat dissipation of notebooks, and in terms of heat dissipation, everyone agrees with the mechanics. However, we can divergent thinking, change the way of thinking, from the notebook's own software to think about whether there is a way to improve the heat, especially the system. Today, I will bring you this article about the impact of Win7 power management on temperature, I hope to bring you some inspiration.

Change the way to see the heat

Inadvertently found that the power management of Win7 does not seem the same as the previous system, so I studied the power management of the Win7 system, and found that the temperature is relatively large. Impact. Speak with the data, in the HP Recommended mode, set the maximum working state of the CPU to 90%, and use the CPU-Z to see the actual frequency at 1198.3MHZ, at which time the CPU is 55 degrees and the GPU is 48 degrees.

For High Performance mode, the CPU working state defaults to 100%. Use CPU-Z to observe the actual frequency at 3056.3MHZ, at this time CPU 60 degrees, GPU 52 degrees.

Later, I tried to set the CPU working state at 10% to 80%, and the actual frequency was basically kept at around 1.2 GHz, with no obvious change. The above data was obtained in the standby state, and opened 2 QQ, 1 web browser. Switching out from the game, CPU100% is about 72 degrees, CPU90% is only 61 degrees. The GPU is not very concerned. After all, the 5830 non-performance version of the graphics card has an independent fan cooling, completely unnecessary.

Compared with the temperature of 13 minutes and 77 minutes, the CPU 90% is really ideal. Just browsing the web, the fan sound is almost inaudible.

P.S. The latest weather, new boot, CPU 35 degrees, GPU 26 degrees, hard drive 23 degrees.

Temperature has a certain impact on the system or the computer, but most users only care about the management of the power supply. It doesn't take much work on the temperature. In fact, this is unscientific, about temperature or power management. Have a certain understanding.
