Thermal Paste Roundup 2015 – 47 products tested with air-cooling and liquid nitrogen (LN2)
Considering the average price of thermal pastes, these products have a huge impact on the cooling performance compared to the price of normal air- or watercooling units. The right choice can result in a nice performance boost and a bad choice can ruin the performance of strong cooling units.
At this point I still didn’t have the time to finish the extreme cooling test but the air-cooling test already shows a good overview of the current situation.
After almost 6 years in lead of the market, GC-Extreme lost the battle against the new Kryonaut from Thermal Grizzly (talking about conventional paste).
In general every product with a delta temperature of up to 10 Kelvin is totally fine to use performance wise. Everything with a higher delta is usually not worth the price because you should find cheaper products with a better performance. I will only explain details of few products. You can find all details such as thickness or technical information in the huge testing table at the end of this test.
Liquid metal products clearly have the highest performance on the market. If you plan to delid your CPU or want to have the best possible temperature you should get a liquid metal product. However you have to deal with an electrically conductive product and it’s usually very hard to remove. Also keep in mind that it must not be used with any aluminium parts.
I prefer normal pastes because they can be used with all kind of coolers, are not electrically conductive and are easy to remove. Thermal Grizzly Kryonaut is the best normal paste on the market at the moment. Taking a look at the price-performance-ratio the Be quiet DC1, Prolimatech PK-2, Thermal Grizzly Hydronaut and Noctua NT-H1 are great products.
The best price-performance ratio has Cooler Master IC Essential E1. The paste is easy to apply and really cheap.
