Share Building a new workstation around AMD’s latest Ryzen Threadripper CPU? You’re staring down a 350-watt thermal challenge that standard coolers simply can’t handle. The massive sTR5 socket and its enormous Integrated Heat Spreader (IHS) demand a specialized cooling solution, and choosing the wrong one means leaving critical performance on the table. Note: If you buy something from our links, we might earn a commission. See our disclosure statement. The market is a minefield of “compatible” coolers with partial coverage alongside dedicated solutions engineered for the task. How do you choose? This definitive 2025 guide is your map. We’ve analyzed every sTR5-compatible AIO and custom water block—from dedicated workstation models by SilverStone and Thermaltake to adapted consumer coolers from Corsair and be quiet!. We’ll break down the critical difference full IHS coverage makes, list the required mounting kits, and provide expert recommendations to ensure your new HEDT or workstation build stays cool and performs at its absolute peak. The Definitive 2025 Guide to sTR5 CPU Cooling | Faceofit.com Faceofit.com Platform Deep Dive AIO Coolers Custom Blocks Comparison Table Recommendations Subscribe The Definitive 2025 Guide to sTR5 CPU Cooling An exhaustive report on every compatible AIO & water block for AMD's 350W Ryzen Threadripper beasts. Don't let thermals throttle your potential. The sTR5 Thermal Challenge Why your old cooler won't cut it. Size Matters: IHS Coverage is Mandatory The AMD sTR5 Integrated Heat Spreader (IHS) is massive, measuring 58.5mm × 75.4mm. This is more than double the surface area of a standard AM5 CPU. Using a cooler with a small cold plate creates thermal hotspots, crippling performance. Full coverage is not a recommendation; it's a requirement for taming the 350W TDP of modern Threadripper CPUs. 4411 mm² sTR5 IHS Area 1600 mm² AM5 IHS Area sTR5 IHS (58.5 x 75.4mm) Standard Cold Plate (Partial Coverage) HOTSPOT Platform Deep Dive Understanding the sTR5 Ecosystem: TRX50 vs. WRX90. TRX50: The HEDT Powerhouse Designed for high-end desktop enthusiasts and prosumers, the TRX50 chipset supports both standard Threadripper and Threadripper PRO CPUs. It's the more "mainstream" of the two, offering incredible performance for content creation, rendering, and complex multitasking. ✓Memory: Quad-channel DDR5 RDIMM support. ✓PCIe 5.0: Up to 80 usable lanes (with 9000-series CPU). ✓Target User: Power users, 3D artists, video editors. WRX90: The Professional Workstation The WRX90 chipset is the pinnacle of the platform, built exclusively for Threadripper PRO processors. It's designed for the most demanding professional applications, including scientific computing, AI/ML development, and large-scale simulations. ✓Memory: Eight-channel DDR5 RDIMM support for massive datasets. ✓PCIe 5.0: Up to 144 usable lanes for multi-GPU and high-speed storage arrays. ✓Target User: Data scientists, engineers, enterprise-level production houses. sTR5-Compatible AIO Coolers Dedicated workstation solutions vs. adapted consumer models.

Check on Amazon Check on Newegg A Word of Caution: TDP Ratings Matter Some "compatible" coolers, like the server-focused Dynatron L36, fit the sTR5 socket but are not rated for the full 350W TDP of high-end Threadripper CPUs. This chart illustrates the performance gap. The Compatibility Minefield Prominent brands that DO NOT support sTR5. NZXT (Kraken 2024 / Elite) NZXT officially states its newest coolers are not compatible. Older models relied on a CPU-included bracket that is no longer provided with Threadripper 7000/9000 CPUs. Avoid for sTR5 builds. Cooler Master (Mainstream) Mainstream lines like the MasterLiquid Atmos and Core do not support sTR5. Cooler Master is developing dedicated TR5/SP6 editions, but they are not yet on the market. Lian Li & Phanteks A review of the Galahad (Lian Li) and Glacier One (Phanteks) product lines shows no official support for sTR5 or its predecessors. These coolers should not be considered for Threadripper builds. sTR5 Custom Loop Water Blocks For ultimate performance, accept no compromises. These blocks offer the best cooling possible.

Future Outlook What's next for sTR5 cooling? The sTR5 cooling market is still maturing. The confirmation of upcoming dedicated AIOs, such as the Cooler Master "PL360 TR5/SP6 Edition", indicates that manufacturers are recognizing the need for purpose-built solutions beyond simple mounting bracket adaptations. As the Zen 5-based Threadripper 9000 series becomes more established, it's plausible that other manufacturers may introduce dedicated coolers to compete in this high-margin segment. The final verdict for cooling the sTR5 platform in 2025 is one of informed diligence. Prioritizing full IHS coverage over brand familiarity is the most critical factor for success.
