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.
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.

| Specifications | Thermal 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. |
