Unexpected power draw

Since i had set up my only pc/gpu to mine, two~three days ago, the power draw and temperature were stable (74w/~59°C). All other stats always normal aswell. Im using lolminer v1.22.
But early today i noticed that the gpu was hot. When i logged in to the hiveos farm it was 118w/83°C!

It is the first time im mining. Im not in a good financial condition.Im trying to make a few dollars and i cannot loose the gpu. Am i missing something? Why the power draw rised like that? Btw, i had only increased the fan speed and, as you can see at the graph, it went back to normal.
Someone know what happened?
