ARCTIC MX-4 (4g) Carbon-Based Thermal Compound, Non-Electricity Conductive, Non-Capacitive

Described by DragonSteelMods as "The BEST thermal compound on the market."

Features
The ARCTIC MX-4 is a new thermal compound that guarantees exceptional heat dissipation from components and maintains the needed stability to push your computer system to its maximum. The ARCTIC MX-4 continues to be overclocker's ultimate choice when choosing thermal compound.

Exceptional Performance

The ARCTIC MX-4 is composed of carbon micro-particles that lead to an extremely high thermal conductivity. It guarantees quick and efficient dissipation of heat from the CPU or GPU.

Review by computer expert

Pros
- Lowered temps by about 5ºC when compared to Cooler Master thermal paste
- One of the best quality thermal pastes (other than Coollaboratory), and about equal to AS5
- No cure time (AS5 can take up to 100 hours to cure, to hit it's lowest temperatures)
- 8 year life span
- Enough included

Cons
- None, maybe price

Summary
This is arguably the best thermal paste out there other than the Coollaboratory's pastes, which do cost more for less. In most benchmarks it's usually equal to or .1ºC +/- compared to AS5. It also has no cure time compared to AS5, and is non-conductive unlike AS5. However, let it be known that this paste is usually within about half a degree or less of MX2, and MX2 is a few bucks cheaper. So if you want to save a couple bucks, just pick up some MX2.
