Linux Fan Not Spinning, Gpu Fan Not Spinning

everytime the fucking machine restarts, it fails devastatingly.

the word: Giving the fans some time to reach full speed...

the script:

#!/usr/bin/expect
spawn pwmconfig
#expect "Giving the fans some time to reach full speed..."
expect "If you do not want to do this hit control-C now!!!"
send "\03"
expect eof

hope this shit works?

echo 255 | sudo tee /sys/class/hwmon/hwmon6/pwm3
echo 255 | sudo tee /sys/class/hwmon/hwmon6/pwm1

i have install something other than that. like i8kctl, some thermal controllers by intel (thermald)? but still gpu fan not spinning till now.

apt install -y lm-sensors fancontrol

pwmconfig

already have cpu frequency under control by running temp_throttle.sh

notes: found controllers dell_smm-isa-0000

Found the following PWM controls:
hwmon6/pwm1 current value: 255
hwmon6/pwm3 current value: 255

Cpu Overheating (Temperature Too High)

linux

cpufrequtils

throttling cpu frequencies by temperature incrementally

the desired temperature is 60.

usually when one throttles the CPU temperature, the GPU cannot be overheated.

it is turning my core i7 into a pentium 3! but not entirely cumbersome.

水冷散热注意

水里加醇类物质可以防止导电

软管加弹簧防止弯折

液体生料带 ergo 5500陶瓷胶 密封胶 液态密封圈 堵漏 用油管防止老化

用水管变径器来改变管径 先用相同大小软管连接目标接头 再用变径器链接变径软管

气压计 肥皂水测试是否漏水

水泵串联并联增加流量和扬程

多水道设计增加导热效率

显卡mos管需要水冷散热 建议看显卡发热红外图其他未水冷的地方贴上散热脊片

主板本来有热管 风扇散热的地方 例如南北桥 供电 如果要拆除 必须替换成水冷 背面也应该加上水冷

氟化液沉浸式散热 可以用潜水泵抽水加冷排

压缩机28度以上防止冷凝水聚集

用水冷弹性弹簧喉夹来链接软管 有快拧接口的要有快拧头连接硬管或软管

用热缩编织管来避免磨损 用阻燃波纹管套住最外面

打磨弹簧套管的两端 避免戳穿软管

用全开放式机架 铝合金框架 方便主板背面 显卡背面冷却装置的安装

工业装甲带缠绕接头部分
