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: So i had an issue. I have a VERY obscure graphics card that seemingly nobody else on earth owns (HP Omen 3070ti) that had horrible thermal issues. It also had incredibly weak mounting pressure so not only could i not find proper pad thickness info anywhere online but the mounting pressure was so weak trying to find the exact combination of soft and hard and thickness of pads was impossible, if i was even the tiniest bit off i'd get uneven die contact and hotspot issues so i gave up on pads and decided to try putty. If you have a worst case scenario like me where mounting pressure is THIS bad putty is the way to go. Mine was SO bad even the squishyness of the putty could prevent proper die contact but putty is so easy to work with all i had to do was keep cutting a bit off and remolding it till i got good contact with virtually zero resistance. Combined with PTM7950 the results speak for itself. My card went from 85c core temp with 105c hotspot under load with 100% fans to 65c core temp with 73c hotspot under load with fans going about 35%. Most of that is the PTM but i NEVER and i mean NEVER could have gotten proper gpu die contact with pads. I tried for 3 days and it just didn't work. With a card that's not total garbage like mine you can just put putty down, squish it down and repaste and forget it. No measuring of pads, no cutting, no nonsense and it works so good. Amazing product and so easy to work with. I'm NEVER buying thermal pads again.

## 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.**

*by D***K on 18 February 2026*

Hands down the best thermal putty for consistent performance. I use this over other brands on my highly overclocked 4090. Coupled with PTM for the GPU, the watercooled card rarely ever goes over 47C even when hitting record setting benchmarks (#1 on multiple 3DMark tests for 9950X + 4090 combo). Even slapped this stuff on my watercooled RAM after replacing the thermal pads. Basically anywhere you use thermal pads, this stuff will perform better. Only major downside is that it's not easy to clean and can be a little fiddly to apply. HIghly recommend watching tutorial videos if you've never handled the stuff. You need far less than you think, but once you get used to handling it, it's super easy to apply.
