Is it cooler? Arctic MX-7 Thermal Paste Review
Cooling Performance
Thermal Paste Testing
To test Arctic’s new MX-7 thermal paste, we used the hottest consumer-grade CPU we had. That’s the Intel Core i9-14900K. This CPU can clock up to 6 GHz and runs HOT. We tested this CPU with a 360mm CPU liquid-cooling solution and compared the MX-6 and MX-7 thermal pastes. As recommended, we applied the MX-7 paste with a cross/X.
Arctic MX-6 VX MX-7
With our i9-14900K CPU, the average core delta temperature dropped by 1.8 degrees Celsius. That’s a notable drop over MX-6. Remember that we changed only the thermal paste we used, and these results were achieved with a thermal paste priced under £8.
If cooling matters to you, you will want to use MX-7 over MX-6. The results below speak for themselves. Both pastes have similar pricing, and MX-7 delivers better results.
When comparing the hottest cores on our i9-14900K, we observed a larger drop in thermal performance when moving from MX-6 to MX-7. The difference was nearly 4 degrees. That’s a big difference. Not bad for a simple change in thermal paste.
