Recent #Cooling news in the semiconductor industry
➀ Meta showcased its IcePack liquid-cooled networking rack at OCP 2025, targeting AI and high-performance networking applications;
➁ The rack uses pluggable optics (not co-packaged) and features 12x 64-port switches with partially populated columns for scalability;
➂ Despite liquid cooling integration, the design retains fans for redundancy, aiming to improve power density and thermal management in data centers.
➀ Traditional chip cooling methods dissipate heat from the surface, creating localized hot spots (dark silicon) that limit performance and energy efficiency.
➁ Researchers propose photonic cooling using anti-Stokes fluorescence, where targeted laser light absorbs heat from inside the chip and converts it into higher-energy light, enabled by a thin photonic cold plate and optical layers.
➂ Early tests show this method outperforms conventional air/liquid cooling with lower power consumption, potentially boosting processing speeds, reducing energy use, and recycling waste heat as light energy.
➀ Tryx Panorama SE 360 offers a 6.7-inch curved AMOLED screen with striking 3D effects, surpassing Thermalright's Wonder Vision in visual design;
➁ Despite its $279.99 price tag, it runs 15% quieter and costs $50 less than Thermalright's competing model;
➂ Exclusive Asetek Adela pump and improved Kanali software provide better customization than rivals, though static image burn-in risk remains.
➀ Stanford researchers developed ultra-thin diamond layers to address chip overheating by spreading heat efficiently, reducing temperatures by up to 70°C in GaN transistors.

➂ Thermal damage and extreme pressure effects highlight the limits of consumer-grade electronics in deep-sea environments.
➀ The South Korean-made Amech SGT-4 thermal paste emits acetic acid vapors, corrodes copper surfaces, and causes permanent damage to CPUs/coolers through 'ant nest corrosion'.
➁ Despite manufacturer claims of RoHS/REACH compliance, chemical analysis reveals its reactive acetoxy-curing formula reduces thermal conductivity by 30% and chemically 'glues' heatsinks to processors.
➂ Community backlash intensifies as the manufacturer dismisses evidence and attacks critics, eroding trust amid widespread reports of hardware damage.
➀ Frore Systems introduced LiquidJet coldplates capable of handling up to 4.4kW TDP, compatible with NVIDIA's Blackwell and next-gen Feynman AI GPUs.
➁ The 3D short-loop jet-channel microstructures reduce pressure loss by 4x and achieve hotspot density of 600W/cm², doubling traditional coldplate performance.
➂ Scalable design supports future processors like Rubin (3.6kW) and integrates flexibility for custom hotspot mapping, improving AI training efficiency and data center PUE.
➀ German overclocker Der8auer tested spray cooling on a Ryzen 7 9800X3D CPU using a makeshift setup, revealing challenges in achieving full IHS coverage.
➁ The experimental cooling method, inspired by supercomputers like Cray X1, relies on non-conductive mist sprayed directly on the chip but underperformed compared to traditional air cooling.
