K5-PRO Viscous Thermal Paste for Thermal pad 20g Compatible with iPhone, Apple iMac, Sony PS4 & PS3, Xbox, Acer Aspire etc

PC specs:CPU-Ryzen 5 3600 at stock speedsGPU-MSI Evoke OC RX 5700XTStuffed into an itty-bitty Sliger Cerberus mATX caseIn an effort to quiet the fans on my GPU, I decided to replace the under-sized and poorly placed thermal pads on the VRMs and memory modules. I watched the Linus Tech Tips video for the K-5 and it seemed like a simple fix for cheap. And since the K-5 thermal compound is not electrically conductive, there wasn't much that could go wrong.I did some benchmark testing before and after removing the existing thermal pads and applying the K-5. See pictures. To maximize heat output, I ran Furmark on the GPU and prime95 on the CPU for 10 minutes and logged temps and GPU clocks to check for equal performance.As you can see, the numbers speak for themselves. Clocks appeared to be unaffected and the thermals definitely improved. That being said, this GPU is still hot as hell, and under actual gameplay loads (and depending on the game) the GPU hotspot temp (aka edge or junction temp) can still hit 100 C. This is better than the 109 C I saw before the K-5. I imagine that the K-5 being applied helps improve overall cooler performance, and thus allows the cooler to remove more heat form the GPU die itself. My next move will be to try a better thermal paste for the die, as the old tube of arctic silver I've been using for 10 years may not work as well as it used to.I forgot to take pictures of the K-5 after I applied it, but it is messy. Be sure to wear gloves and avoid getting it on anything other than the GPU. I didn't try to clean it up, but I imagine it would imagine it is not easy to get out of clothes.Overall this stuff works. If you are comfortable with taking apart a GPU (and it isn't that hard, just be sure to use the correctly sized screw driver) then this is an easy way to squeeze some better performance out of hardware if you aren't satisfied with it and can't really do anything about it now (I would think of getting a new GPU but I ain't feeding the scalpers).

Purchased this stuff along with some PTM7950 thermal pads to repaste my laptop that was thermal throttling like crazy the last few months. After doing a cleanout and repaste with this stuff and the PTM7950, I went from an average of 91c-ish to an average of 69-70c. Let the laptop do a "burn in" period after seeing initial results as I couldn't actually believe the improvement I saw and I STILL can't believe it. This is on a 2021 RoG Zephyrus G14, where liquid metal was used on the CPU from factory which is an awful thing to use on a laptop, so could be part of the insane improvement I've seen as that kind of improvement just still doesn't make sense to me, but I don't care. I'm flabbergasted and can't recommend this stuff enough at this rate.Attached 2 images of my overall temps after a 2 hour benchmark and 6 how gaming session with no real "break" for the laptop in between. Temps are overall 15c cooler on average, up to 20c. Amazing product

Great thermal paste for repasting your computer components. Easy to use and good consistency for application. Keeps temperatures lower as it creates a nice bridge between the components.

I went in thinking it wouldn't be as sticky as it was, so I struggled greatly to get it in place, and was too foolish to put it in a piping bag. Learn from my mistake: just put it in a little zip lock bag, cut a teeny hole at the end, and pipe it on, instead of me smearing on little bits at a time like a doofus.Anyway, the product itself, once applied properly, has functioned very well. I put it on my 7900 xtx because the dang thing was getting to 110c hot spot with a 30+ delta, and now it's sitting pretty at over 20 degrees cooler with a <20 delta.Word to the wise, though: look at a slightly larger amount of paste. The product itself was good, if difficult to handle, but the quantity was to be desired; my gaps were roughly 1.5mm.

The best use of this paste for me was to bridge areas where a thermal pad was missing and I did not know the size of the original pad. It's easy to apply, effective, and affordable.A few heat cycles will eventually burp out any air bubbles as this stuff melt and solidifies repeatedly. Don't worry if there's a bit of air in it when you apply.I don't recommend using this over a large area such as many GPU memory chips. It is not fun to clean up later if you need to remove the K5 for various reasons. It will melt slightly and flow over the edges of the components. No matter how I tried to portion the application this melting and overflow seemed to happen at some point.Using a very soft bristled toothbrush and some high purity rubbing alcohol was effective in cleaning the K5 later.Don't get me wrong -- this stuff is amazing for many applications and areas you won't be removing the heatsink often. It's pretty much a set it and forget it type deal.
