UTP-X Ultra 16.8w/mk Thermal Putty for VGA GPU IC Processor Rapid Cooling Thermal Pad Replacement Heat Blocking Putty (20g)

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.

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.

Used this to revamp a 3080 FTW3 12GB. The card is known to have slightly off pad sizes. I wouldn't consider any putty "easy" to apply but it eliminates fuss over pad sizes and tension when applied correctly. While time consuming, it's a great one stop pick. If you intend to use this on your VRAM like I did you might need more than 20g. I used about 35g. The card never had serious cooling issues but this brought the hotspot down 4c from 80c, more notably MOSFETs/VRAM/Power never break 65c, all thanks to improved thermal transfer. I should mention this is all on air in a sub tropic area. Very much worth it if you're willing and careful.

This stuff is AMAZING. Absolutely amazing. I cannot recommend it enough. I'd been struggling with thermal modding my Powercolor 9070XT Red Devil for a few weeks now. They must use some weird proprietary sizing for the VRAM thermal pads, as 1.0mm was too big and prevented core contact, but 0.5mm was too small and led to warmer VRAM temperatures than I'd like. So I relented and bought this stuff after hearing great reviews, and it was entirely worth it. Being putty, I didn't have to worry about sizing at all. It squished down perfectly and now I have probably have the coolest VRAM on any air-cooled 9070XT. I added 5mm pads to the backplate behind the VRAM in addition to this putty, and now my temps don't even see 70C at 4k ultra in any game. It's magnificent. It was super easy to apply as well. You just scoop it up and push it down on the VRAM chips, then the cooler mounting does the rest. I truly didn't think I could get the chips this cool without water cooling. Overall 10/10. I'm running a +400MHz overclock on my VRAM and it doesn't even care. My GPU is quiet, cold, and calculated. I'm never using thermal pads on my VRAM again. This stuff is a cheat code.

Used this to replaced the nasty, dried up thermal pads on my GPU and it works great. You do not need to apply much since it'll squish and spread in reassembly.

This is extremely dry and stiff. I found it difficult to apply using the spatula, so I ended up using my hands. Be careful not to use too much, since it doesn't really squeeze out like paste and some other thermal putty. Seems to work fine though.

Works as expected. Helped fix heat problems I had with my gaming laptop. Having the three finger covers helped to work the putty without getting skin oil on it to soften the putty before applying them to the VRMs. Glad they included them so I didn't have to buy a new pair of gloves (or a box of disposable ones).

For what it's worth, ADHD hobbyist review and comments. Summary at end, here's TLDR: Seems to be intended for highly mobile and vibration prone applications for it's resistance to applied forces and dense consistency. If vertically mounting or securing to a vehicle based use, this may be a good option. Be sure of your intended use case! UX Pro Ultra is a fairly stiff product and may cause unexpected inconsistency in thermal performance where mounting forces are carefully balanced. It can be squished to perfect gap thickness, but could interfere with critical tolerance components if pre-prep isn't thorough. Hopefully not a knockoff clone, but seems to work well. Medium grey colored and a but crumbly when moved, has a notably dry consistency, and is difficult to work with. More of a "spreadable thermal pad" compared to some salvaged contaminated K5 pro "liquid thermal pad". Upsiren UX Pro Ultra has a strong tendancy to stick to itself and any surface it has been worked on or rubbed into, so after cleaning the surface for application it's recommended to take a small amount and work it into the contact area until residue can be seen left behind. Absolutely wear gloves if there's chance of touching the UX Pro, and clean or change frequently as well as the provided spatula to avoid sticking large amounts for ease of application. If possible, something like a clipped dental irrigator for precise application is recommended. Overall, only a marginal improvement over K5 Pro for thermal efficiency. I would recommend reserving for use cases where strong mounting force is possible as UX Pro Ultra will peal away from applied surfaces fairly easily due to it's preference to adhear to itself. Performance margin is negligible unless heat dissipation is truly critical, especially when direct contact or use of precise shims are possible. Major difference in difficulty of use, but notably UX Pro Ultra will be much easier to clean and salvage due to it's tendency to stick to itself compared to K5 Pro that is much more paste like and sticky. If concerned with K5 Pro possibly running out from place, I would note that I have K5 in use long term in vertically mounted gpu as well as gaming laptop for travel that is normally stored vertical not flat. In 3 regular maintenance/cleaning checks at 8month intervals I have noticed no runout of K5 Pro at all. UX Pro Ultra may be best for non-critical high heat components, or otherwise extremely mobile and vibration prone applications.

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.

Highly effective. 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.

La use para mí tarjeta gráfica y va muy bien mantiene las temperaturas correcto entre 70 y 78°c a máxima capacidad, es de fácil manejo y la cantidad correcta para una tarjeta gráfica grande

The product comes with an authenticity sticker code which you can type on the official website. The putty itself is easy to apply and after pairing it with ptm 7950 (glozaar) my legion 5 pro temps dropped from 90C to 75C. Very happy with the results the fan speed dropped gradually
