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

I got tired of getting worried about buying the right size thickness of replacement pads after buying two XFX RX 7900XTX Merc310 video cards I wanted to repaste with MX-6 on the GPU die. I never trust OEMs on using premium thermal paste or pads, and I was right. One card had too little paste, the other bubble areas from pump out. Forget using the spatula for anything other than just grabbing a bit of this stuff out of the bottle, go for full coverage rubber, nylon, whatever gloves. I learned it's best to start the flattening process yourself with a single finger. Use the spatula to cut off excess, but be ready for this stuff to come apart and get stuck to your gloves when you least expect it. Cleaning the surfaces with 91% or above isopropyl alcohol helped it to stick especially on the VRAM. **One major note. Expect to use 1 full bottle of the larger size of this stuff per graphics card (GPU). Each VRAM row in my card was 8GB, so 3 full rows of VRAM for the 24GB. Add in the capacitors, ICs, other originally covered with pads and I can guarantee you it's best to have a full large bottle versus 1 small bottle per card!!** it was worth it though. The VRAM temps alone from this stuff dropped about 8C without load and almost 10C under load. Was it perfect application..probably not but who cares.

it is incredible how well it works, best product out there, a year later after installing and the paste is not even close to dry

The thermal paste on my ASUS G15 2021 needed replacing and so did compound on the VRMs. Don't bother looking for the exact pads manufacturers use as the thickness can be very tricky.With some time and patience you can work this putty to cover the VRMs just right, and even if you screw up, you can always keep molding it and removing/adding what you need.Thermals are great too.

This paste is nice and easier for installation of different components with different sizes that need thermal pads but not the correct height. As far as temps go it does keep the laptops and gaming consoles at low temps. I mainly use this to replace the ones on the Xbox series s and X and PlayStation 5 thermal putty. Mainly on the PlayStation 5 because Xbox users are cheap as h3ll and they don’t want to pay to get them service. That’s why Xbox series x when they die they die.

I used this to replace 2.25mm thermal pads on a 3080 since 2.25mm is an odd size and impossible to find for a reasonable price. The thermal putty worked great and reduced the vram temps by around 15 degrees. The card also runs a whole lot quieter and I can finally enjoy games without my pc sounding like a jet engine.

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 several SSRs (Solid State Relays) that got pretty hot in my application, so I got heatsinks and used this putty to couple them. This may be over the top for my application, but, it does lower the SSR temp quite a bit. Enjoy.

Well it did it's job and I have no complaints about performance. Was a pain in the ass to apply since it was both too sticky but also to slimy to really mold it to shape like I was hoping.Expect to use rubbing alcohol a lot for clean up, 91% and up is recommended, and I would invest in a proper box of rubber gloves instead of the little finger ones it comes it if you want dexterity and for application to be not so messy.
