The thermal paste does what it advertises and works great for my gaming pc. It is great value and you get a lot of uses. For everybody that owns a pc, make sure you check your CPU temp before deciding to reapply. Reapply does come with risk so make sure it is warranted.

5.0 out of 5 stars One of the best thermal pastes I have ever used!
Reviewed in the United States on May 25, 2024
I have been using this product since 2000 to put between the heatsink and the processors of the computers I build. I also like to use it to fix laptops that just quit working for no apparent reason or just shut down mysteriously. Sometimes it is an indication that the thermal paste had dried out and is no longer transferring the heat from the processor to the heat sink. this is common occurrence on desktops and laptops. Very common on heatsinks that came with the tape style thermal compound already on them with a stick and peal approach. You need to scrape off the old Thermal sticker or paste off the processor and the heatsink wash off any remaining paste or sticker residue with alcohol and let it dry and then put a pea size amount to start and take a spudder or something to spread the Artic Silver evenly on the processor, make sure that the silicon is covered by the thermal paste and then put the heat sink back and clamp it down on the processor. Reassemble the computer and you are good to go. Thermal paste and even Artic Silver is made to be replaced ever 5 years or so once it dries out and is no longer transferring heat away from your processor. I will say that the Artic silver works much better than traditional paste and tape because it has ground up silver to help transfer the heat even when the past is dry, and it fills in the gaps between the silicon and the aluminum for maximum contact and heat transfer. If you want a good heat transfer on your processors and heat sink this is the way to go.

5.0 out of 5 stars Cooler operating temps and fan doesn't hit warp speed anymore - Quality and reliable compound
Reviewed in the United States on March 15, 2016
The previous reviews and five star rating from over 3,000+ people speak for itself. My 2009 Macbook Pro was no longer displaying anything on the screen, and the logic board was the culprit. Over many heating and cooling cycles, the soldering joints holding things together develop fractures. This resulted in my fans kicking on hard almost constantly for about a year prior to failure. If your logic board has failed, go to your favorite search engine and look up "baking logic board" and you'll get a ton of information on how to go about trying a last ditch effort to resurrect your computer/laptop.

1. Remove your heat sink/cooler and clean thoroughly with isopropyl alcohol (I used 70% alcohol and it seems to work just fine). You'll also want to thoroughly clean your CPU and the immediate surrounding area of old thermal compound. Old compound can crack and become hard, so try not to spread it too far from where it was previously. When the alcohol hits the old compound, it'll thin out and become a huge mess, so try and contain it! Once you think you have everything clean, clean it again, and possibly another time. You want to make sure you have a 100% oil free and clean surface on both the CPU and heatsink. When you think it's clean enough, give it a wipe with a clean microfiber or coffee filter.

2. Apply thermal paste is one of the most subjective things about it. How much, what shape, whether or not to spread it across the CPU, etc. The size of the CPU on a Macbook Pro is relatively small and I put a the equivalent of a swollen grain of rice dead center of the CPU. If you've ever played with silica gel balls, it was about that size. I didn't spread it with a credit card or do anything other than apply in the center. When you spread it out over the top of the CPU you run the risk of getting air bubbles, gaps in coverage, and spillover. Many videos will suggest different things, but I thing a circular dot in the middle provides your best coverage. It's difficult to get it right, and I had to do it twice the first time, but haven't had any issues since.

3. Install the heatsink evenly and in one movement, DO NOT lift it once it touches the compound as that'll result in bubbles/gaps. Once in place begin tightening everything down evenly and put the rest of your computer back together.

4. Once everything is together, run your computer through multiple heating and cooling cycles to "age" the compound and have it seat properly. This will ensure you get an even bond between the heatsink and CPU for maximum thermal transfer from the CPU to the heatsink.

It took me two tries to get the correct amount right, but since then I've been running with these paste on for almost eight months and have seen no issues. The fans rarely kick on hard, and if they do it is under a lot of load. I wish I picked this up as soon as I noticed my fans constantly running as it could have saved my logic board from failure.

5.0 out of 5 stars Experienced long time PC builder, this is my favorite!
Reviewed in the United States on January 25, 2016
I've been building PC's for a local computer shop, (everything from high end, water cooled gaming rigs, budget builds, cheap email boxes, linux rigs, servers, parts bin rigs, and everything in between,) myself, (usually nicely spec'd budget gaming rigs and home media servers,) and family, (modest "future proofed" and parts bin builds,) for about a decade.

I've used a lot of different thermal pastes, including the pads that come on stock coolers, pastes that come with aftermarket coolers, glues, ceramics, copper, silver, some weird white stuff, lots!

The Arctic Silver 5 has, in my experience, consistently lowered temps and helped to get the most out of any cooler I've purchased for myself, someone else, or a clean out of an older machine.

I'm really impressed by the features AS5 has up it's sleeve.

Pros:
-It's performant. Even on chips that I've uncovered from "custom builds" from others where the CPU heat spreader is scratched, or a stock cooler has a poor finish, AS5 seems to improve performance ALWAYS. Even if it's one degree, or keeps the temp down an extra minute or so on a failing part, it works very, very well.
-It cleans up very easily, even after being caked on for years. (A bit of isopropyl alcohol goes a long way!)
-It keeps a long time. I've found tubes of AS5 in tool sleeves that I've lost for a year or two, and had no issue using the AS5 in the tube. Most other included thermal paste/greases I've used will harden or get gummy.

Cons:
-It seems to not be available locally. If you need to run out to a local supply shop I've usually only found other products, so I make sure to have some on hand.
-It's the same price per tube as much bigger tubes of others. I still think that due to how well it performs, it's worth buying more often.

Bottom line:
-If you're installing a new CPU, cooler, building a new PC, have overheating issues, are cleaning out an older machine, give AS5 a shot. It's a very good performing product, and for a few bucks, it's often the saving grace that can restore PC/hardware performance.

Was shocked on the size of the tube but it’s okay. Used this for a graphics card and the iMac. Works great.
