Summer heat, CPU temperature rose, Desktop is OK, notebook on the trouble. It's a very unsettling affair. But I've found a solution. Instead of using a heatsink bracket, it is http://www.aliyun.com/zixun/aggregation/7432.html from the source to solve the problem. Not only can reduce the cooling also can prolong the battery use time, even extend the CPU service life.
Meat test Results (early March): The previous cpu100% can reach more than 61 degrees, now live running Mprime can only reach 53 degrees. Mprime never had a passion. Peacetime use of the temperature now live only about 40 degrees. Before 8630.html "> Sometimes it reaches 50 degrees. The battery is 1 hours and 20 minutes old and can now live for 1 hours and 35 minutes.

There are two ways to reduce the CPU voltage.
1. Use Cpupowerd (AMD Exclusive) 2. Use LINUX-PHC (Intel, AMD can use)
1. Using Cpupowerd (AMD-specific)
Advantages: 1 Direct voltage value adjustment, simple. 2. Do not compile the module Disadvantage: Only support AMD K8 (Athlon, Athlon64 (X2), Sempron, Opteron, turion ...) Features: Self-CPU frequency regulator, and cpufrequtils conflict and need to adjust.
Installation Arch Installation Direct
Code:
Yaourt-s Cpupowerd
Ubuntu here under the source code compilation installation Http://sourceforge.net/projects/cpupowerd
Code:
Tar-xzf cpupowerd-x.x.x.tar.gz CD CPUPOWERD-X.X.X/SRC Make sudo make install
After installation, check your CPU parameters First
Load MSR Module
Code:
sudo modprobe msr
Load POWERNOW_K8 Module
Code:
sudo modprobe powernow_k8
Code:
$sudo cpupowerd-s Cpupowerd 0.1.2 Warning:this program could incorporated damage to your hardware! Vendor:amd Family:k8 Model:7 mastercpuid:0 Affected cpuids:0 Current Voltage (VID): 0.6750 V (39) Current frequency (FID): 0 MHz Keyword frequencies:800 1600 MHz
You can see that the default voltage is 1.0 v. Remember it
