With a thermal conductivity exceeding 16.8 W/mK—triple that of common thermal pads—it ensures superior cooling performance. Its sticky, non-electrically conductive formula applies easily, replaces pads up to 3mm thick, withstands temperatures up to 250°C, and offers a lab-proven operational lifespan exceeding 1000 days, making it ideal for high-demand computing and automotive electronics. ## Description Applications *Automotive Electronic Control Units *Heat sink, Memory modules *LED Lighting, LCD-TV *Military Electronics *Power Supplies *Telecom services *Wireless instruments *Automotive control services 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: Best thermal pad replacement - 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. ## 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.** ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CSZ8BFZS | | Are Batteries Included | No | | Best Sellers Rank | #63,713 in Computers ( See Top 100 in Computers ) #80 in Thermal Pads | | Brand | UPSIREN | | Customer Reviews | 4.0 4.0 out of 5 stars (1) | | Date First Available | 30 January 2024 | | Item Weight | 91 g | | Item model number | UX PRO | | Manufacturer | UPSIREN | | Package Dimensions | 13.11 x 10.01 x 3.4 cm; 91 g | ## Images ![UTP-X Ultra 16.8w/mk Thermal Putty for VGA GPU IC Processor Rapid Cooling Thermal Pad Replacement Heat Blocking Putty (20g) - Image 1](https://m.media-amazon.com/images/I/61NZvPcw+lL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐ Expensive and difficult to use but it works *by N***L on 24 November 2024* 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.

But a pain to shape and apply. If you have used putty before this is a great product if not be ready to spend lots of time to do all the vrms and components. Stick to thermal pads if you dont have the paitience but if you need actual performance go for it. Highly satisfied. ## Frequently Bought Together - UPSIREN Ultra 16.8w/mk Thermal Putty for VGA GPU IC Processor Rapid Cooling Thermal Pad Replacement Heat Blocking Putty (20g) - PTM7950 40x80x0.25mm Phase Change GPU Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck CPU GPU SSD M.2 Laptop - 4 Pack 13W/m.K Thermal Pads, 100 x 100mm 0.5mm+1mm+1.5mm+2mm Silicone Cooling Pad Non Conductive Heat Resistance Extreme Odyssey Cover with Dual Self-Adhesive Films for PC Laptop PS4 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/629085418-utp-x-ultra-16-8w-mk-thermal-putty-for-vga](https://www.desertcart.hr/products/629085418-utp-x-ultra-16-8w-mk-thermal-putty-for-vga) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-11*
