furmark

Hello. I have a question about FurMark ( the GPU stress tester.) I am wondering if FurMark can damage my GPU or even my CPU. My GPU is XFX Radeon HD7870 Double Dissipation and never hits over 80°C The highest it got is 78°C whilst playing Space Engineers for 5 hours on MAX settings. Is it safe...

I'm not really sure how to describe this. While playing a game, or running FurMark, my laptop will quit charging for a minute, I get a huge FPS lag spike, and then it begins charging again. It will keep doing this most of the time. I have learned that giving it better ventilation helps...
