Best Thermal Compound

No curing
Non conductive

Noticeable improvement in temperatures with my i7-2600K @ 4.5 GHz over Artic Silver 5 roughly 5°F lower on load and about 1 °F on idle.

None

Also used this on my PS3 to help reduce the risk of it having another YLOD, which the lack of cure time really makes the difference here.

TOP CRITICAL REVIEW
NOT in retail package, cap was off mine, defective

Artic MX-4 is far better then the popular Artic Silver 5, in terms of thermal conductivity, lasting effectiveness, and electrical insulation.

But not when you get a product that comes in shady retail package with cap off! Get the MX-4 4g one, these come in plastic/sealed retail packaging and you KNOW you are getting a real new product and not hardened open tube/syringe.

The cap was off, the box provides no assurance product is new. This box they send it in is a complete joke. Used product can be returned and then you get old thermal compound. Like I said, get the MX-4 (4g) they come in sealed plastic, no worries like the 20g version which is easily used and returned.

In terms of worst --> best thermal compounds for CPUs and GPUs (installed between core and cooling/heatsink element):

Worst thermal compound type: Ceramic-based thermal grease

Mid-range thermal compound: Metal-based thermal grease contain solid metal particles (usually silver or aluminum). It has a better thermal conductivitythen Cermaic and is more expensive than ceramic-based grease. it CAN conduct electricity which can be a problem if you have a MoBo short. :(

My personal choice (MX-4 type): Carbon based. generally more expensive than metal-based thermal grease, but worth the extra 3 -5 bucks paid IMHO.

Best but hard to find for mainstream consumers: Liquid metal based (this is NOT Artic Silver 5 type products!!). Some thermal pastes are made of liquid metal alloys of Gallium. These are rare and expensive!

My final thought: get the MX-4, it is Carbon-based and work really well, but get the 4g MX-4 to get a real new product, not something tampred with.

Details
SpecificationsThermal Conductivity (W/mk): 8.5Viscosity (poise): 870Density (g/cm3): 2.5Net Weight: 8gThe ARCTIC MX-4 is a premium-grade thermal paste with exceptional performance and ease of application. It is an electrically non-conductive paste that is applied between CPU / GPU and designated coolers to transfer the dissipated heat from the components to the heat sink. Since the ARCTIC MX-4 is a metal-free compound, it eliminates the risks of causing short circuit and in turn adding more protection to your computer.The new formula in the ARCTIC MX-4 features optimal thermal conductivity and low thermal resistance. These characteristics effectively dissipate the emitted heat from the core components.The consistency of the ARCTIC MX-4 is designed for simple application. Its texture is just thin enough to spread onto components using fingers without creating much mess.
