It makes no sense win paired with the rest of the article. Granted that particular pc never did anything other than simple internet browsing mostly email related and word processing.
Just to sum up this buying guide: there is literally no difference in thermal conductivity and price? Allow me to write a competing guide…. Does anyone have any idea what temperature range mosfets screwed to a heatsink likely reach in a e-bike 72 volt dc motor controller?
And what type thermal compound paste is BEST for better cooling in this type application? There is an excessive amount of important information available on this topic here but… Is there a website that answers these kind of questions with more definitive answers? Please e-mail me back at.. What the hell kind of article says the 4 out of 5 linked products are electrically conductive? I mean come on if your going to post a article at the very least you could get the details of the products you link correct..
Come on now Newegg — I expect better of the company Ive bought nearly all my PC related components from for last 18yrs or so.. Save my name, email, and website in this browser for the next time I comment.

As a result, heatsink installation will require additional focus to apply even tension to ensure proper spread. The NTE A paste is an industrial silicone thermal compound designed for diodes and transistors in commercial and residential electronic equipment. NTE A is silky smooth and spreads very easily. The large, 1oz Thermal Grizzly Conductonaut liquid metal thermal compound has a very thin, runny consistency and is applied to the CPU integrated heat spreader with a syringe delivery system and capillary needle applicator tip.
Excess material can be siphoned off using a special extraction tip by pulling the syringe plunger to withdraw excess liquid metal. CoolLaboratory Liquid Pro is a liquid metal compound that is applied with a syringe and capillary tip to the CPU integrated heat spreader, and it ships with a scouring pad and alcohol swab for prep and cleanup.
Application and spreading of the liquid metal are made easier with cotton swabs and generous pressure for even distribution. Liquid metal can cause reactions with some metals, such as aluminum, and some reports of reactions with copper are also documented by end-users. Liquid Metal Compound LM ships as a syringe with a capillary applicator tip. Spreading the compound is made easier with cotton swabs and generous pressure to develop a consistent coating on the CPU IHS.
Can cause reactions with aluminum and other metals. Here's a breakdown of our recent testing, and we'll be adding new pastes to this list over the coming weeks and months. A bit further down, you'll find our original round of testing with 85 different pastes, some of which we've revisited in this new performance hierarchy.
That should give you a good idea of how other pastes that we haven't retested yet would compare to the newer pastes. We'll go into our breakdown of how we test these thermal pastes below, but the key takeaway here is that a single thermal compound can perform differently based upon several variables, such as what type of cooler and mount you use.
To cover all the bases, we've tested every thermal paste with three variables:. Below you'll find the temperatures we measured on our standardized test bench, and as always, lower temperatures are better. We've also included value charts in the album below as well. As shown in the slides above, the outcome of the different testing scenarios resulted in some interesting comparisons among the compounds.
Air Cooling — Low Tension Mount Liquid metal compounds make their way to the top of the temperature chart with slightly cooler values than the traditional pastes. Interestingly, the difference between the top and bottom of this chart is less than 4C.
When we look at each compound in terms of unit cost-per-gram, liquid metal compounds are generally more costly, making their overall performance value more of a luxury than a necessity. However, Phobya LM bucks this trend as it shows you can get good liquid metal compound performance at bargain pricing. Only a few minor changes to the pecking order have occurred, and these easily fall within the tight margins of standard deviation.
Small differences in temperatures jostle the chart a bit, but overall the more budget-friendly compounds show much more promising performance value due to relatively close load ranges. We see a trend that most good and great thermal compounds perform very similarly, but might be worlds apart in price per gram. The performance value chart shows most of the liquid metal compounds with a poor value-per-gram rating, but once again, Phobya LM proves to be the outlier for that sub-category with its budget price tag.
Key Takeaways Thermal compounds might always be compared and debated over, but the simple fact remains: PC system building needs thermal compounds to effectively dissipate thermal loads. Without them, our beloved gaming and content-producing machines would struggle to keep components cool during heated frag sessions, heavy workstation computations, or just simply browsing the web.
Not every system will need the most expensive compound, so even the most budget-minded system builders can rest easy knowing that even lower-cost pastes can still prove very effective. You can see our historical testing results with far more pastes after the test setup. For our thermal compound tests, we use the same hardware, overclock, and configuration for each and every test to minimize environment variables in our testing. We tested each thermal paste with a low-tension air cooler mount, high-tension air cooler mount, and a high-tension AIO liquid cooler mount.
Each application was given a 1-hour burn-in using Prime95 with ten load and cooling cycles over the course of the hour; six minutes each with a ten-second cool-down between. Each testing load session was then executed for a one-hour load period, again using Prime For the air cooling low- and high-tension tests, we used a large Noctua NH-D15 air cooler.
We created the low tension mount environment by torquing the mounting screws to 1. The low tension mounting tests help simulate cooler installs that might not use a backplate like push-pin coolers or those that do not allow high tension and compression across the CPU integrated heat spreader.
Also, repeated tests are not consistently possible with push-pin mounted coolers: The pins can degrade after several mount cycles, which meant we needed to simulate these to maintain consistent test results. Our high-tension air cooler mount involved tightening the mounting screws fully to the mounting plate and shows thermal paste performance with air coolers with backplates that allow for tighter mounting. We performed these tests with the AIO pump block fully tensioned tightened.
We didn't test the AIO with a low-tension mount because liquid coolers almost always employ a backplate that allows a high-tension mount. Overall, each compound was evaluated and stressed over a regimen cycle covering six hours with two different coolers and different mounting tensions, making for no less than 90 hours of compound testing for our initial round of tests.
Here's our legacy thermal paste testing chart that we generated back in As you'll notice, many of the same popular pastes in are still on the market, making it into our new round of testing. We do have new testing equipment for our updated tests, such as a more modern CPU, motherboard, and coolers for our tests, but we adhered to the same test methodology employed in these prior tests.
That means that you can use these legacy tests as a decent approximation of how the newer pastes compare to the older pastes, too. Included in this guide: 1.
