Our thermal paste test protocol is very young, it is based on an Intel Alderlake platform with an I9-12900KS and an EVGA Z690 DARK KINGPIN. The tests are performed under the same conditions with a Heatkiller IV water block at constant pressure.
The I9 12900KS is set to get 250W of load on cinebench R20. The Pcore are at 5200MHz, the E-core at 4000MHz and the cache at 4400MHz for a voltage of 1,335V bios LLC +25%. Thermal paste applications are done crosswise on the CPU, this is the method that works best with all thermal pastes on the market. The water block is mounted and tightened to the screw stop to let the springs apply the right pressure. Then, a cinebench R23 stress test is run to bring the thermal paste up to temperature with 10min of heavy load. Three cinebench R20 are launched in a row. Taking care to have the same water temperature between each benchmark start. Each thermal paste is applied three times with three cinebench R20 per application. The minimum delta T° value between the water and the CPU is recorded among these nine measurements.
As can be seen, NZXT’s thermal paste is not at the level of the competition. Although it is less expensive than the major brands such as the NOCTUA NT-H2, it does not manage to compete with the MX-4 from Arctic, which is less expensive.
