TravaCabrera Is this Nvidia GT 530 an OEM GPU from a prebuilt? If so, which manufacturer and build is your computer? What inspired you to reapply the thermal paste? Did you just obtain this part and wanted to refurbish it, or did something indicate that the GPU was overheating? Which software tool is indicating the 100C temperature and that it's entering power savings (thermal throttling?) mode? If not too much trouble, would you mind listing your full specs. My reason for asking you this is to determine if your integrated graphics exceed your GPU
Side question: Are you located in the United States, Europe, or other? A GT 530 is an under-powered GPU that is surpassed by modern integrated graphics, no offense. I only ask this question in the unlikely event that someone in the community might have a hand-me-down GPU that they wouldn't mind parting with to help a fellow gamer.
