Alphacool Announces Apex 17 W/mk Thermal Grease

Recently Alphacool announced its Apex thermal grease with a rated thermal conductivity of 17 W/mk. This is considerably higher than the average, and anything rated above 8.5 W/mk is generally considered high performance. Alphacool accomplishes this by utilizing “nano-particles” with lower thermal impedance. The Apex Thermal Grease will be available at Alphacool’s website for $15.62 and come in a four-gram syringe. Below is Alphacool’s press release, along with additional specifications.

Alphacool Apex 17 W/mk Thermal Grease

Alphacool introduces the new Apex thermal paste. With a thermal conductivity of 17 W/mk, it enters the circle of the most powerful thermal pastes on the market.

The main objective during development was, of course, to increase the thermal conductivity. However, points such as viscosity and durability should not be ignored. Alphacool was able to optimize the viscosity so that the Apex thermal paste is particularly suitable for high contact pressures and is still easy to process. The main ingredient of Apex Thermal Grease is a nano-powder with a very low thermal impedance. This makes it possible for electronic components to be cooled efficiently, thus extending their durability and improving their reliability.

The thermal paste is delivered in a 4g applicator with a screwable cap. The supplied amount is sufficient for several applications and can be stored in the applicator to protect it from drying out. The Apex 17 W/mk Thermal Grease will be available in the Alphacool online store (item number 1022240) from 06/16/2022.
