Prolimatech Pk-1 Nano Aluminum Thermal Compound - 5g

This is my 2nd tube of PK-1. My first tube lasted me over a year. First off, people need to stop thinking/believing TIM reduces temps of your CPU or GPU, because it doesn't. All TIM does is improve the contact between two surfaces. The heatsink does all the cooling, not the TIM.PK-1 is the best TIM-in-a-tube period. This is after many years of Arctic Silver and other brands. From over 10 years of reapplying stock thermal paste what I have discovered is that the true and tried Arctic Silver completely fails to transfer heat when used on medium to poor contact surfaces. This evidence can be found on direct-pipe style heatsinks and heatsinks with poor contact surfaces (like on many stock CPU and GPU coolers).I have a MSI 6970 Lightning and for the longest time I kept thinking that either the pressure on the Frozr cooler wasn't strong enough or the cooler was somehow faulty. I reapplied AS5 twice using the 5-dice method (bigger pea in the center and four smaller peas in all 4 corners) and my temps still shot up to 80C on graphic intensive games like BF3 and Hard Reset and I clean the dust on my heatsinks regularly (every 3~4 months). Then I saw a report from Skinnee Labs showing how different TIMs hold up against different levels of contacts.Their report was dead on and it explains why my AS5 failed to provide good contact on my GPU, so I gave PK-1 a shot.After I applied PK-1 to my 6970 Lightning and ran a stress test, I couldn't believe my eyes, it was the TIM afterall. PK-1 kept my temps hovering around 65C whereas it used to shoot up to 80C. This experience reinforced Skinnee Labs TIM roundup. While most TIMs will do fine when there is 'great' contact other TIMs fail when there is medium to poor contact.

This compound is definitely ahead of the game as far as cooling goes; on average I saw 4-7°C differences going from AS5 to this. My only complaint is that the benefits deteriorate over time. You will notice after 8 months or so(in one case I noticed after 4 months) that your temperatures start to increase. This is because the TIM dries out over time and will need to be reapplied periodically. I would imagine that this issue is less pronounced in systems that are not using high end overclocks, but let's be honest here: we would not be on this page if we were not trying to overclock our systems.Overall I would say this is a commendable product. It is easy to apply and clean and does not leave residue on the surface it is applied to. If you find you are constantly adjusting or changing parts in your system and want a TIM that provides great performance for its price, then this TIM is for you. If you want something that is more "set it and forget it," then you should consider other options.

It works fine for my needs. The tube is five grams which will last me a very long time. Most of the other high-grade thermal compounds were four grams or less for about the same price as the PK-1 five grams.It does have a very good screw on lid that should keep the paste from drying out at the end. I did squeeze out just a tad to see if it was dry, and it was fine. The PK-1 is made in Taiwan. I could not find an expiration date on the box or tube. You can tell how much is in the tube by shining a light up close to the tube. The round cylinder end closest toward the cap has a clear spot, so you will know that your close to running out or not.I applied the PK-1 using the lentil/pea/small dot method to the center of my core i3-4360. Temperatures are just fine. It does come with a small plastic spreader with a handle, but I did not use it since I have good results by letting the heatsink spread the paste.

Bought this to replace the pre-applied thermal compound on my Corsair H60. The difference between the PK-1 and the Shin-Etsu paste that was on there before at first did not seem to be as drastic of an improvement as I was hoping. Then, after playing a game or two I noticed that my non-overclocked i5-3570K did not seem to be breaking fifty/sixty degrees C when under load. At idle my CPU now stays below thirty-five degrees C on a warm day and hovers around twenty-nine or thirty-two degrees C. It says on the package that no burn in time is required, but in my personal experience a day or two of use, and therefor placing my CPU under varying stages of stress, seemed to help following the initial application.

Sometimes you do get what you pay for... This thermal paste is universally well rated by professional reviewers, and I found my personal experience to be in line with those results. Temperatures were better than expected, especially considering I was using a reputable competitor.For those who don't get the results you are expecting, try applying this product more liberally than you normally would. I found the product performance IS NOT hindered by overapplication but is by underapplication. Experiment if you are unsure, there is plenty in the tube for multiple​ installs.

Well I'm not sure about fusion, but this is a great thermal medium for heat transfer in a computing system.I was using Arctic-5 stuff, but this compound transfers heat much better. Comparatively, I get 3-4 degrees C lower temps on my CPU and my GPU using this on my water cooling loop compared to AS-5.I've also been using it without a change for three years. And it still performs the same as it did on day one. I'm not sure ANY compound can do that!Quality, reliability and performance all wrapped in a 5 gram tube. Don't get the AS-5! This is where it's at.

I've used a bunch of different thermal pastes from Arctic Silver 5 to TC Grease 0098. This is the only thermal compound I have ever re-ordered to get more of. It's great when applying, it does a great job of maintaining consistency and not drying out in the syringe and has great performance.Sure, it's pricey compared to cheap stuff but remember that each 5g syringe gets you a dozen or more applications.
