UTP-8 14.8w/mk Thermal Putty for VGA GPU IC Processor Rapid Cooling Thermal Pad Replacement Heat Blocking Putty High Performance (20, Grams)

I recently ordered this UPSIREN UTP-8 thermal putty to tackle a major heat issue on a friend's older ASUS laptop with an RTX 2060. Out here in Indio the summer ambient temperatures are brutal and standard thermal pads simply do not cut it. The factory pads inside this laptop were dried out and crumbling. Sizing and cutting traditional replacement pads is a fool's errand. If you get the millimeter thickness even slightly wrong, the copper heatsink will not make proper contact with the main processor die. That completely ruins your entire cooling system. This pink putty completely solves that problem by acting exactly like moldable clay. You just roll it into small pieces and place them directly onto the VRMs and VRAM memory chips. The wonderful thing with the UTP-8 is its incredible compressibility. When you screw the laptop heatsink back down using a crisscross pattern the putty effortlessly squishes out to fill the exact gap required. It guarantees perfect mounting pressure for your main chips while delivering an impressive 14.8 W/mK of thermal conductivity to the surrounding power components. Just remember to avoid during application is putting the putty on unpopulated solder pads. My client's motherboard had empty rectangles where additional VRAM chips could have been placed but the factory lazily stamped putty there anyway. You only want to apply this to the actual black silicon chips and grey power blocks to avoid wasting the material. Working with this putty is incredibly satisfying once you get the hang of it. I recommend leaving the clear plastic film on your primary CPU thermal pad (TPM7950 used in picutures) while you wrestle with this pink material to keep your critical surfaces perfectly clean. Once the laptop was reassembled, the VRM and core temperatures dropped so drastically that I was able to comfortably run Cinebench stress tests maxing out in the low 70s on a laptop that was throttling during idle before. If you are doing a full laptop teardown or replacing the thermal interface material on a desktop GPU this twenty gram jar provides more than enough material to get the job done right the first time.

Used this to replace the 6 year old thermal putty on my Xbox Series X. There was just enough to cover the essential parts. Easy to work with, not chalky.

Perfect solution for my laptop. under stress test VR temp dropped from 98 deg C to 70 deg C. not bottlenecked on thermals now.

I used UPSIREN UTP-8 together with PTM7950 during a repaste on my gaming laptop, and the results were much better than I expected. At first the CPU hit around 90–96°C, which scared me, but after a few heat cycles everything settled. Now, during actual gaming in 4K, my CPU stays around 70–74°C and my GPU around 65°C, which is a huge improvement compared to before. Performance also feels smoother and games load faster. The putty is easy to apply, fills gaps well, and it’s non-conductive, so I never had to worry about damaging anything. Overall, paired with PTM7950, UTP-8 worked great for me. Definitely recommended.

Muy buena masilla térmica. Un poco arenosa y dificultosa de manejar pero muy maleable. El kit que viene junto con la masilla es muy versátil.

I decided to go with this putty for my 2025 G16 Strix, with the ultra 9 275HX and Nvidia 5080 GPU. The putty used from factory was leaving my VRM temperatures much warmer than I would like. I saw a 20°C drop after applying this putty to the VRM‘s. Absolutely fantastic, and I highly recommend it. You can never go wrong with Upsiren.

This stuff is awesome! Has all the thermal transfer capabilities of high performance thermal pads but the putty form removes any need for figuring out the various pad thicknesses. It's very easy to apply, went on quickly and had my 9070XT back up and running with way better memory temps. So glad I finally tried this stuff, I'll be using it on all of my GPUs in the future.

Amazing product and easy to work with and apply. Works as expected!! I put it on my Razer Blade 16 with rtx 5090 in combo with Honeywell ptm 7950 and saw temps of 10-15 less for CPU(AMD Ryzen AI 9) and 5-10 less for the GPU.
