Alphacool has released Apex 2, a new thermal paste that offers higher thermal conductivity than standard silicone compounds. This release matters because better heat transfer allows CPUs and GPUs to run cooler under heavy loads. Users building or upgrading systems can now choose a material designed for improved thermal performance.
New silicone compound offers high thermal conductivity for CPU and GPU cooling
The company developed this paste in collaboration with Halnziye. It is a silicone-based compound intended for direct application to CPU and GPU heat spreaders. The formulation aims to fill microscopic gaps between the processor and the cooler.
Specifications
- Thermal Conductivity: 17.3 W/m·K
- Thermal Resistance: 0.0006 ℃·in²/W
- Operating Temperature: -20℃ to +130℃
- Viscosity: 130~140 Pa·S at 20℃
- Package Price: 9.98 EUR (around $11.51)
Apex 2 achieves a thermal conductivity of 17.3 W/m·K. This high conductivity supports a low thermal resistance of 0.0006 ℃·in²/W. The material operates safely within a temperature range of -20℃ to +130℃. Its density sits between 2.6 and 2.7 g/mL.
The paste maintains a viscosity of 130 to 140 Pa·S at 20℃. This viscosity helps the material stay in place during installation. It also exhibits a dielectric constant of 2.3 and a volume resistivity of 2.0E+13 Ω·cm. These electrical properties ensure the paste does not conduct electricity. The dielectric strength reaches 2.0 kV/mm. A 2g package costs 9.98 EUR (around $11.51) in the EU.
