Delidded Ryzen 7 5800X3D processor runs 10 degrees Celsius cooler


A PC enthusiast called Madness (opens in a new tab) put an AMD Ryzen 7 5800X3D under the knife. He pulled off a tricky operation to remove the integrated heat sink (IHS) without killing the chip – a procedure popular with the overclocking community dubbed delidding. After some to push (opens in a new tab) by Hardware Luxx editor, Andreas Schilling, Madness has shared some exciting test results, comparing key CPU performance stats while gaming before and after delid surgery. The delidded Ryzen 7 5800X3D ran faster, consumed less power, and cooled 10 degrees Celsius in the same system when taxed while playing Forza Horizon 5.

The Ryzen 7 5800X3D with its IHS removed smiles alongside telltale but unsophisticated tools – sharp knife blades. The Twitter user used the blades to lift the edges of the IHS while simultaneously applying between 150 and 200 degrees Celsius via a heat gun. With previous-generation processors, this process is somewhat nerve-wracking. Yet the 5800X3D adds a layer of danger by positioning a host of surface mount components between the IHS “legs”. These would be too easy to accidentally stab during unboxing. More established CPU designs can be phased out with less risk.

After removal, an enthusiast can replace the factory TIM (thermal interface material) with something like a liquid metal compound or run the chip “bare” with the risk of direct cooler contact to the silicon. Instead, Madness followed to say they added the Conductonaut compound to the dies and replaced the IHS.

In the end, the results of the delidding are more important than the process, and Madness achieved an impressive result. The Ryzen 7 5800X3D cooled 10 degrees Celsius under heavy workloads after the operation. This is not the only advantage; the 3D V-cache chip also showed improved power consumption and better boosted clocks.

The Hardware Luxx editor succeeded in obtaining another one (opens in a new tab) exciting image of Madness. The photograph revealed a vacant second pad area in the 5800X3D with a strip of protective material removed. It’s not normal for a single Ryzen CCD to have a second pad like this.

AMD’s Zen 4 processors will arrive later this year, and 3D V-cache releases will follow with only a small time gap.
