Arctic MX-2 vs Phobya Thermal Pad Ultra 5W/mK: Comparison
What is the difference between Arctic MX-2 and Phobya Thermal Pad Ultra 5W/mK?
Recommended use is the dividing line, Arctic MX-2 Mainstream CPU/GPU against Phobya Thermal Pad Ultra 5W/mK Mainstream CPU/GPU; Phobya also markets it for VRAM, VRM,.... Paste segment is not the same on both, Standard Paste on the Arctic MX-2 versus Pad on the Phobya Thermal Pad Ultra 5W/mK.
Arctic MX-2 vs Phobya Thermal Pad Ultra 5W/mK: which one fits your build
Buy the Arctic MX-2 for cost-sensitive mainstream builds where a budget compound is the priority, though it is the wrong buy for high-end or overclocked builds needing stronger conductivity. The same goes for buyers replacing an existing MX-2 application with the same known product. It is not the one for anyone who can afford MX-4's modest premium for better documented performance. it is not built for buyers wanting Phobya's higher-conductivity Thermal Pad XT line instead. It is equally the pick for VRAM, VRM, and mainboard chipset cooling needing a compressible pad to bridge height differences up to 4mm. It is the wrong buy for CPU IHS-to-cooler contact where a conventional paste offers thinner bond lines. Our rating of the Arctic MX-2 (5.4/10): A carbon-based budget legacy compound from Arctic, functional but dated next to MX-4/6/7. Our rating of the Phobya Thermal Pad Ultra 5W/mK (5.8/10): A small single-piece pad with modest conductivity, a niche fit for specific gap sizes.
Where the two are identical
The common ground is wider than the gap: electrical conductivity are identical here.
