Used for my CPU. As a GPU I would recommend Noctua. In my testing of a hot 5700xt it's 2-3s lower. I would spend my good stuff (Noctua) on something that idles around 30 degrees and needs a lot of use. Iceberg Thermal FUZEIce lays down in a thick layer and does not push out. I think it's due to the rise in temperature. Noctua just flows out like water. 2 types of thermal paste. It's good to have both for different applications.
