Open the cover of the Ryzen 9 7900X: The full load temperature is greatly reduced by 20°C

Der8auer, a well-known overclocking enthusiast from Germany, is a master in the DIY world. Overclocking technology is naturally not a problem, and the opening skills are also quite good. Although AMD’s Ryzen 7000-series CPUs are just getting ready for retail, Der8auer has found a Ryzen 9 7900X and opened it with a tool developed by itself.

After opening the cover and cleaning the surface of the Ryzen 9 7900X chip, Der8auer used a special fastener made by himself to test the Ryzen 9 7900X after opening the cover.

When the Ryzen 9 7900X abandoned the heavily integrated heat sink (IHS) and changed it to direct-touch heat dissipation, the CineBench R20 multi-threading score increased from 11693 to 12062. The full load temperature has dropped from 90 ℃ to 70 ℃, and the peak power has dropped from about 220 watts to less than 190 watts, and the effect is very obvious. Der8auer believes that in order to maintain compatibility between the CPU coolers of the AM4 and AM5 platforms, AMD used a thickened copper top cover, which affected the cooling efficiency.

As can be seen from the video, Der8auer has great skills. Even if the average player has the relevant tool kit, it is difficult to complete it, and the risk factor is relatively high. It is not recommended for ordinary players to do this.
