Talking about the influence of Windows 7 power management on temperature

These days have been discussing the heat dissipation problem of notebooks, and the improvement in heat dissipation, everyone agrees with the mechanical. 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 Win7's power management seems to be different from the previous system, so I studied the power management of the Win7 system, and found that it has a greater impact on temperature. Speak with pictures and data. In HP Recommended mode, set the maximum CPU working state to 90%. Use CPU-Z to see the actual frequency at 1198.3MHZ. At this time, the CPU is 55 degrees and the GPU is 48 degrees.

For High Performance mode, the CPU working state is 100% by default. Use CPU-Z to observe the actual frequency at 3056.3MHZ. At this time, the CPU is 60 degrees and the GPU is 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.
