AMD’s newly launched Ryzen 7000 series has received a relatively good reception despite its impressive performance. One of the reasons that drive users higher is the higher temperatures, which are usually around 95°C at demanding loads. Although AMD maintains it is a safe operating temperature, some have tried lowering it, and “der8auer” overclocking has shown that “delid” of processors It can give a drop of about 20 ° C.

According to “der8auer”, the high temperatures are due to the processors’ heat spreaders being too thick, which is the effect of compatibility with coolers designated for AM4. So the logical step from there is to try “patching”, by grinding the heatsink. This is exactly what the Youtube profile “Jayztwocents” is doing right now on i video.

This time around, the flagship Ryzen 9 7950X is running like a guinea pig, and as usual the processor is around 92°C in the test run before the intervention starts. After a lot of sanding, the heat spreader is 0.8 mm thinner but at the same time flatter, and Jayztwocents notes that the cooling block no longer contacts well with the heat spreader. With this fix, the intervention results in a clear but relatively modest improvement of about 4–5 °C with a slightly higher clock frequency.
Before the intervention, use Arctic MX-4 cooling paste.

Jayztwocents is also trying to change the cooling paste from the Arctic MX-4 to the more expensive Thermal Grizzly Kryonaut Extreme. This means another improvement of about 4-5°C, with a final result of about 84°C. Lower temperatures allow overclocking to 5.4GHz across all cores of a Youtube profile instance.
Testing by Jayztwocents confirms der8auer’s theory that the thickness of the Ryzen 7000 Series heatsink prevents effective heat dissipation for processors. At the same time, the improvement was much less than what was shown by “der8auer” using “delid”. Thus, such an intervention may be more attractive to enthusiasts who want to lower the working temperature of the processor as much as possible.
