Alphacool Apex 2 Thermal Paste vs Phobya NanoGrease Extreme: Comparison

Alphacool Apex 2 Thermal Paste vs Phobya NanoGrease Extreme thermal conductivity compared

The gap that matters here is thermal conductivity: Alphacool Apex 2 Thermal Paste 6.7 W/mK against Phobya NanoGrease Extreme 16 W/mK, which puts Phobya NanoGrease Extreme 58% ahead. There is a split on viscosity as well, 130 Pa-s on the Alphacool Apex 2 Thermal Paste versus 85000 Pa-s on the Phobya NanoGrease Extreme. Recommended use is not the same on both, High-end CPU/GPU on the Alphacool Apex 2 Thermal Paste versus CPU/GPU Air and Water Cooling on the Phobya NanoGrease Extreme. There is a split on density as well, 2.6 g/cm3 on the Alphacool Apex 2 Thermal Paste versus 2.7 g/cm3 on the Phobya NanoGrease Extreme.

Who each one is for

it is not built for buyers who specifically want liquid-metal-level conductivity. It is equally the pick for high-end CPU and GPU builds, overclocking rigs, workstations and servers wanting Alphacool's current-generation paste. It is the wrong buy for anyone needing a confirmed silicone/carbon base disclosure, which Alphacool has not published for this formula. it is not the pick for single-application buyers who don't need the reusable syringe format. It also earns its place with CPU and GPU builds wanting high officially-rated conductivity with a reusable, mess-free syringe. Avoid it for sub-ambient extreme cooling setups where Alphacool Subzero is more explicitly positioned. Our rating of the Alphacool Apex 2 Thermal Paste (6.7/10): A high-end Alphacool paste with a solid published conductivity figure, though independent review coverage is thinner than bigger paste-specialist brands. Our rating of the Phobya NanoGrease Extreme (6.4/10): A screw-cap syringe format with a strong published conductivity figure from Phobya's higher tier.

Where the two are identical

Everything else lines up. Electrical conductivity and paste segment read the same on both, so those are not worth weighing.
