I was using the stock thermal compound from my Corsair H55, and it worked fine, no worries, but I am building another PC and im like, well, i'll just get some fancy thermal compound anyways! Well, I lowered my temps idle by about 3 degrees, and was feeling way more confident over-clocking my FX-4300, which worked well. Went from the base clock of 3.8ghz, and now it's stable at 4.3! Very pleased.

This is a much thinner (aka low viscosity) paste than most other brands, which makes is spread thin more quickly and easily. It fills in microscopic bumps in poorly milled, lower quality heatsink contact plates, which is great. It’s simpler and quicker for an inexperienced user to see if they applied too much as well. The manufacturer doesn’t state anything about a break-in period where viscosity changes and the materials sort, etc like other more chemically varied pastes on the market so I assume it doesn’t have one, which is nice. Also, it’s non-conductive and non-toxic. In comparison tests against Arctic Silver, this paste unfortunately didn’t win (see next section) but it did come close enough to be a consideration if you’re not looking for the absolute best cooling solution, especially considering the lower price. It was, after all, REALLY close and this paste is thinner and easier to apply in some cases. Overall, this is a more cost-efficient, easy paste for applications where thermal performance just needs to be acceptable, making this the #1 choice for re-applying a large volume of stock coolers, etc and because of its simplistic, homogeneous materials, it should stay stable longer than high performance pastes. Because of that, I’d considering it best in its specific class and it easily gets a 5 star rating.

ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for all processors (CPU, GPU - PC, PS4, XBOX), very high thermal conductivity, long durability, safe application, non-conductive, non-capacitive
  • Volume / Net Weight: 4.0g
  • Thermal Conductivity: 8.5 W/mK
  • Specifications: Thermal Conductivity (W/mk): 8.5 Viscosity (poise): 870 Density (g/cm3): 2.5 Net Weight: 4g The 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 text...

Price. A number of suppliers charge as much as double for single quantities of this product. It's easy to match the price if you're in business building computers and need the stuff measured in dozens (or ounces). Or I could run by the local store and get something functional for the same price, but not a top tier product.

kept my i7 12700k under 100 Fahrenheit (cold) while under 100% load, after a week of use, it cooled down to 70-85 Fahrenheit IDLE!

-Great performance. My CPU temp is around 28C at idle and caps out at 63C under sustained stress testing =O. Using a Cooler Master Hyper 212 cooling tower. Maybe I went overboard because the Ryzen 5 5500GT isn't the spiciest processor out there... but I can't say I regret it. -Included plastic spatulas and cleaning wipes were very helpful. Mixed results with the applicator tip.

So easy to install and quick to act. Also shipping was so fast I was impressed

Awesome Thermal Conductivity & lower temps, easy application

Better cooling performance and longer life than MX-4
