Replacing old paste with fresh high-quality paste like Thermal Grizzly Kryonaut or Noctua NT-H2 can lower CPU temperatures by several degrees Celsius. The three best pastes in the test, the Arctic MX-6, the Thermal Grizzly Kryonaut, and the Noctua NT-H2, are about 1.4 to 1.7\u00b0C ahead of their less strong competitors. Personal testing shows NT-H2 excels in temps, ease of use and longevity. Testing reveals that while NT-H2 occasionally shows brief temperature peaks, it performs at the same level as Kryonaut and MX-6 99% of the time. What I particularly appreciate about NT-H2 is its consistent performance over time – it doesn’t pump out or degrade as quickly as some competitors. The paste comes with Noctua’s excellent applicator and clear instructions, making it foolproof even for first-time builders. While not the absolute cheapest option, NT-H2 delivers reliable cooling with exceptional longevity that justifies its price for those prioritizing stability over raw performance numbers.<\/p>\n

Buying Guide: How to Choose Thermal Paste<\/h2>\n
\n

When selecting thermal paste for your Intel 14th-gen processors, understanding the key factors ensures optimal cooling performance. Keeping the Intel Core i7-14700K and Core i5-14600K cool can be challenging especially when overclocking due to the high heat output. Using a beefy high-end air or liquid AIO cooler is the most impactful upgrade you can make. This needs to be combined with proper case airflow, fresh thermal paste application and undervolting for the best thermals. Thermal pastes are essential for a PC build. However, picking the highest conductivity thermal paste isn’t always the best idea. Testing shows these three thermal interface materials are only separated by a mere 0.9\u00b0C. So, ideally, you should get whatever you find cheapest unless you really care about temperatures. Price expectations range from $0.70\/gram for budget options up to $8.45\/gram for premium compounds like Kryonaut.<\/p>\n
