The complete thermal pastes of the coolers were compared with MX5, GD900, Alsil and KPT-8. On the Voiaka YouTube channel, they found out which thermal pastes make sense to take and which ones are better to refuse. Seven models participated in the experiment.
The host of the Voiaka YouTube channel compared seven thermal paste models in terms of efficiency. Among them were stock DeepCool, gold complete thermal paste, AlSil-3, technical (complete thermal paste without a name), GD900, KPT-8, MX5.
The test bench included an AMD Ryzen 5 7500F processor on the B650, a DeepCool 850 power supply, two KingBank memory sticks, a 2 TB drive, and an RTX 3070 video card.
Conclusion
In general, the supplied thermal pastes really performed well. Therefore, if you are assembling a new computer and the cooling system comes with thermal paste, then use it. MX5, for example, turned out to be only 2 degrees cooler than gold thermal paste: 35 and 37 degrees, respectively. You can see all the test results in degrees in the image above.
Also, domestic and foreign thermal pastes performed approximately equally on more or less average hardware. If you are building a computer for 7500F, 7700X, 12600K, 13600KF, then feel free to use the supplied thermal paste. She is also quite normal.
