These Set Points的意思|示意

这些设定点 In addition to the Thermal Monitor feature, the boxed Intel Pentium 4 processor fan heatsink uses a high quality variable speed fan which allows the processor to remain within its operating thermal specifications by running at different speeds over a short range of internal chassis temperatures. The processor fan operates at a low speed while internal chassis temperatures are low. If internal chassis temperatures increase beyond a lower set point, the fan speed will rise linearly with the internal chassis temperature until the higher set point is reached. As fan speed increases, so does the noise that the fan generates. Systems should be designed to provide air around the boxed processor fan heatsink that remains below the lower set point. These set points, represented in Table 1 and Figure 1 can vary by a few degrees from fan heatsink to fan heatsink.
