Frequently Asked Questions

AI
For most gaming builds, mid-range pastes like Arctic MX-4 provide excellent cooling performance at a lower cost. High-end options like Kryonaut offer marginal gains that may not justify the price unless you are extreme overclocking.
Applying thermal paste is straightforward if you follow basic steps: clean the surface, apply a small pea-sized amount, and spread evenly or let the cooler pressure spread it. Many kits include tools and instructions to simplify the process.
High-quality thermal pastes can last between three to five years. However, if you notice sudden spikes in CPU temperatures or frequent thermal throttling, it may be time to clean the old paste and reapply a fresh layer.
