Expensive and difficult to use but it works
i have years of experience refurbrishing cards, this product is very difficult to manage and to apply. online there are some tutorial bun honestly i don't raccomend to spread things everywhere without any minimum of diagnostic with your fingers. Be informed that 20g are not enogh to cover the VRMs and ram chips of a full card. (in my case a 3090) i raccomend to use oven paper and place a specific amount on it and roll them since u don't reach a proper thinkness of each related thermal pads you are going to replace and cut with a cutter the portion that u need (is really time consuming but the final result will be better and without messing the pcb). Spreading the putty without a control is going to cause imperfection causing high pressure spot and bending the pcb, since we don't want to destroy our card pay attention.
