Zalman's STG1 is an easy to apply compound that increases the thermal efficiency of your computer's CPU cooling system by eliminating the miniscule air gaps between the processor and the heat sink. Instead of messy squeeze tubes STG1 comes in a bottle with a handy in-cap brush.

Application is a simple process. Remove the heat sink, brush the STG1 onto the heat sink, re-attach the heat sink. It conducts heat away from sensitive components and improves the efficiency of your cooling system. Keep things cool and functioning under the hottest action!

  • newegg Maximizes Heat Transfer The high-performance ZALMAN ZM - STG1 thermal compound eliminates minute air gaps between the heat source and the heat sink caused by their uneven surfaces for the optimized heat transfer.
  • newegg Ease of Use A brush applicator is attached to the cap for easy application. The bottle with a tightened cap ensures up to 10 applications of the thermal grease.

3 out of 5 eggsWorks good but.........

Pros: Easy to apply (once you get it to thin out) , no mess

Cons: Not much in bottle, not sure how some people got 8-10 uses, I did 2 processors and two video cards and the bottle was done, also the first two bottles I opened had the same issue, the compound was almost dried up (in the bottom of the bottle no less) but if you soak the bottle in a cup or container of some sort with fairly hot water for about 10-15 minutes it becomes fairly easy to use. The brush itself seems like it could have stood to be just a bit longer so it can reach the bottom of the container, I had to use a Q-tip to get full use out of a bottle. My only other thought would be that if I ordered it again it would have to be if it was shipped by other means than the USPS

Other Thoughts: They should put suggestions on the packaging on how to get the compound to loosen up. I'd also have to say they should consider finding another way to weigh this product, I honestly can't believe that there's 3.5g in the bottles when they appear close to empty when you open them. I think I would have given it a higher rating if it had more in the bottle and had not been close to being dried up.

1 out of 5 eggsNot good anymore

Pros: sadly no pros anymore

Cons: - As thick as other paste but stickier than most.
- Can't even retrieve stuff from the bottle.

Other Thoughts: This used to be my favourite paste by far due to it's ease of use. It was easier to apply than standard paste and you didn't have to fear of using too much : it didn't have any consequence if you did. It was the best choice IMO for a guy like me with limited experience applying paste. However, the last two bottles I got (one several weeks ago and another one last year) where unusable. The paste had become so thick and sticky that I could not even retrieve all of it from the bottle. Applying the sticky goo on the CPU was a total mess leading to abysmal results in the heat department. Either they changed the recipe, it's too sensible to cold temperature or the it has a short shelf life.

4 out of 5 eggsGreat paste as always, but applicator is lacking

Pros: As always, this is highly recommended paste, easy application, great temps, easy to store and reuse.

Cons: The applicator stem is too short, leaving nearly half of the product unreachable. Had to go buy a separate brush to get the remaining out. Also, while the weight may be correct (unsure), the bottle usually comes about 1/3 full, so you may get one or two applications (YES, I know how much to use), before having to figure out how to get to the rest at the bottom of the bottle.

Other Thoughts: Good purchase, would recommend, just be prepared to be slightly frustrated trying to get it all out. I liken the experience to a bottle of A1 sauce. Superb quality, love using it, but it is a strain trying to get the last of it out of the bottle when it runs low.

5 out of 5 eggsGood Value

Pros: Much better value than single use packages. What are they thinking? Only building one computer? For about the same price as a single-use package, this one has 3 1/2 grams of grease, so it can stored and reused on my next build.

Cons: None.

4 out of 5 eggsTiny Bottle, Great Compound

Pros: Ridiculously easy application, great control, even coating.

Cons: Tiny amount of compound. Just barely enough for one application to 2 surfaces.

Other Thoughts: Like tons of other reviewers, I love the ease of application of the compound. Got a nice even coat on both surfaces (CPU & Cooler Block). It does what it says, solid connection for heat transfer. My temps are 16° C. at idle and no more than 40° C. when tasking the CPU.
Wish I had more of the stuff for future applications. Hear that, Zalman?

5 out of 5 eggs

Pros: Applied paste to approximately 5-7 cpus and I still have PLENTY for more. I think some reviews that mention that there isn't enough paste in the bottle.. they apply too much. Either way, it does it's job and does it well.

Love the brush

Cons: None

5 out of 5 eggsGreat Product

Pros: Applied and temps dropped 6-8 celsius from stock paste. Easy to apply and it doesn't have a cure time... 43-47Celsius to 34-37

Cons: Not much in the jar it was only enough for a am3+ socket processor and a Nvidia gtx 660

Other Thoughts: I was a bit stumbled when I realized it came like fingernail polish figured I'd give it a try anyways the temp drops made it well worth and applying with a brush is kind of fun
