Imagine spending $12,000 on a CPU and then cutting it open to make it even more powerful. Sounds crazy, right? But that's exactly what Geekerwan did with AMD’s Ryzen Threadripper PRO 9995WX, a beastly 96-core Zen 5 processor designed for workstations. Their goal? To tackle the age-old problem of heat dissipation in high-performance CPUs by transforming the integrated heat spreader (IHS) into a fully functional water block. And this is the part most people miss: by machining coolant channels directly into the IHS, they effectively turned the CPU’s own heat spreader into the cold plate, eliminating the thermal bottleneck that plagues even the best cooling solutions.
But here's where it gets controversial: this isn’t just a simple mod. It’s a high-risk, high-reward experiment that requires access to expensive machinery and carries a significant chance of damaging the CPU—AMD’s most expensive desktop processor, no less. So, is it worth it? Geekerwan’s results are impressive: they achieved an all-core overclock of 5.325 GHz, with Cinebench R23 scores soaring past 205,000 points. During testing, the CPU package power reached around 1,340W, with core temperatures staying comfortably between 30°C and 50°C—even under extreme loads. The total system draw? A staggering 1.7 kW.
To pull this off, Geekerwan didn’t just wing it. They started by testing their idea on older Ryzen Threadripper 1900X CPUs, machining channels into spare heat spreaders and comparing them to conventional high-end water blocks. They then refined their design to better match the chiplet layout, ensuring even coolant flow to prevent hotspots. The final setup features a four-port top cover with two inlets and two outlets, strategically aligned to direct coolant over each CCD. The channel pattern evolved from straight runs to an S-shaped layout, maximizing surface area and heat transfer efficiency.
The build also includes an industrial chiller, a large reservoir, and two 50W Bosch pumps sourced from Mercedes—because why not go all out? But let’s be clear: this isn’t a weekend DIY project. It’s a complex, costly endeavor that most enthusiasts can’t attempt. Geekerwan even had support from ASUS, who provided a removed IHS for planning and supplied parts for the test system, including a current-generation motherboard.
Here’s the burning question: Is this mod a game-changer for extreme cooling, or is it an over-engineered solution for a problem most users won’t face? And more importantly, does the risk of damaging a $12,000 CPU outweigh the potential performance gains? Let us know what you think in the comments—we’re eager to hear your take on this bold experiment!
