No Fan control and thermal throttling on HP C640 Dratini

I have a HP Pro C640 Core i5 and on Windows the fans won’t spin up until i set (scan for hardware changes) on device manager or restart the laptop when it get’s hot as hell, in games it just shutdown suddently, someone told me to use ectool, but i has no ideia how to download, install or use it

ectool is included with CoolStar’s Chrome EC driver.

Its path is C:\Program Files\crosec\ectool.exe
