I have gpu throttling l want to undervolt my gpu

I just checked the performance of the MX130 and you need all the power you can get:


If it is running hot then it is time for the laptop to come apart and the fan assembly to be removed so that you can clean the end of the little radiator in there. I have tired to cheat and do this with compressed air and it never works. Taking it apart works every time with heat issues.
