I tested 4 popular thermal pastes from Amazon using the SAME overclocked CPU, SAME cooler, and SAME 20-minute stress test to find out which one actually performs best.

Tested Thermal Pastes:
• Thermalright TF7
• Arctic MX6
• Arctic MX7
• JLJ Thermal Paste

Test Setup:
• i7-7800X (overclock preset)
• ASUS X299 board
• Low profile cooler
• HWInfo stress test
• 20 min idle + 20 min load per paste

Results include idle temps, max temps, and averages so you can see the real differences.

If you're building or repasting your PC, this will help you choose the best value thermal paste.
