Arctic MX-4 vs Corsair TM30: Comparison
What is the difference between Arctic MX-4 and Corsair TM30?

Arctic MX-4 vs Corsair TM30: which one fits your build
Take the Arctic MX-4 for mainstream CPU builds on the tightest thermal-paste budget. Current guides specifically recommend this tier of paste for chips like a Core i5 or Ryzen 5. It also earns its place with buyers who value an extremely long, proven track record over the newest formula. Few thermal pastes have this much accumulated real-world usage data behind them. It is the wrong buy for flagship or heavily overclocked CPUs. Arctic's own MX-6, or Thermal Grizzly Kryonaut, both covered elsewhere on this site, deliver meaningfully better performance where that headroom actually matters. The Corsair TM30 is the one to take for first-time builders who want a straightforward, applicator-guided application and Corsair-ecosystem builds pairing with Corsair coolers or cases. Avoid it for builders chasing the highest published conductivity numbers, where Corsair doesn't compete on paper against TFX or Kryonaut. Our rating of the Arctic MX-4 (7.3/10): an extremely well-reviewed budget staple with a huge installed base, though durability has been questioned on laptops and bare dies over long periods. Our rating of the Corsair TM30 (5.6/10): Corsair's budget entry paste; some reviewers have flagged durability concerns over long-term use compared to Corsair's pricier lines.
