Thermal Paste Air Cooling Results

Air-Results And Buy-Recommendation

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, Prolimatceh 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.
