Significantly lower temperatures without a heat sink

Significantly lower temperatures without a heat sink

Images and temperatures of a decapitated Ryzen 7 5800X3D were posted on Twitter. Although AMD’s newer processor is soldered, it seems worth removing the heatsink.

With the Ryzen 7 5800X3D, AMD introduced a new processor in April that uses 3D V-Cache for the first time. Specifically, this means that during the CPU Another chip is even housed, which serves as the L3 cache and thus significantly expands it. As a result, AMD promises more performance on the one hand, but on the other hand the chip should create additional distance to the cooler and thus make heat exchange more difficult.

Outside the heat sink

Despite the added heat barrier, it seems worth removing the rear heatsink on the Ryzen 7 5800X3D. At least that’s what Twitter user @Madness7771 reports, who posted images of a decapitated Ryzen 7 5800X3D yesterday. The solder with which the CPU and IHS were actually connected with good heat conduction is clearly visible.

In addition to the images, @Madness7771 also posted test results showing the temperatures with and without the heatsink. Not too many details about the test scenario were announced; all that is known is that the CPU was heated by Forza Horizon 5 and cooled by a Noctua NH-D14. Also, the box used apparently only had a box fan.

In this scenario, the Ryzen 7 5800X3D reportedly only ran at an average of 67°C without a heatsink, eleven degrees lower than the headless model. There is also a clear difference in maximum temperature of ten °C, which means that the CPU can consistently maintain the maximum clock on average. In principle, beheading the Ryzen 7 5800X3D seems worth it, even if the associated risk doesn’t really outweigh the benefits.
