Review: 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.
Review: I have a 6600xt and like most 6000 series amd gpus mine ran pretty hot especially on the hot spot which is on the pcb and not the die on these cards. I had tried repasting and repadding twice and no change in temps. I used this putty on the pcb and tg duronaut on the die and my temps dropped 15c on average. As for working with it I recommend gloves as it leaves behind a residue but it was easy to use and did not make a mess.

## Features

- 1. Ultra thermal putty is a high quality gummy / sticky thermal paste designed for use on memory chips and GPUs of various computers.
- 2. Ultra thermal putty can replace soft thermal pads that are used on computers (up to 3mm thick)
- 3. Ultra thermal putty has thermal conductivity K>16.8 W/m.K (at least 3 times higher than common thermal pads that are used on computers and comercial electronics)
- 4. Ultra thermal putty is applied very easily directly on the component and has no electrical conductivity. It can be heated up to 250 degrees (Celcium) and has a long operational life time
- **The theoretical service life in the laboratory can reach over 1,000+ days.**
