A Redditor, ComplexSupermarket89, transformed an old MSI RTX 3080 Ventus graphics card by repurposing a 100W car amplifier as a custom heatsink, reducing GPU temperatures by 10°C. The DIY project involved using Arctic MX-7 thermal paste, better thermal pads, and replacing the backplate with the custom heatsink. Additional modifications included building a custom fascia and fan shroud from scrap aluminum, as well as installing three 92mm Thermalright RGB fans. Despite the success in lowering temperatures, the creator plans to further enhance cooling by adding a recessed fan to the heatsink. The mod, while considered a bit extravagant for an older GPU, showcases a passion for customization and innovation in PC hardware.

Commodore backs down over FPGA firmware lockdown — it won’t now try and block third-party firmware installs but will stand firm against bricked modded units

Commodore has reversed its decision to block third-party firmware installs on the C64 Ultimate computer, allowing users to experiment freely. However, the company will not provide support or replacements for modded units that become bricked. The initial plan to restrict non-Commodore FPGA firmware caused a divide among fans, leading to heated discussions on social media and forums. Commodore now emphasizes user freedom but warns that using community-installed firmware is at the owner's risk, with no free support or warranty service provided for damaged units.

AMD's memory-boosting EXPO 1.2 is here, adds support for three Chinese memory vendors — performance gains could be muted until Zen 6

AMD has released EXPO 1.2, a memory-boosting technology for AM5 motherboards, enhancing memory overclocking capabilities and supporting three Chinese memory vendors. Notable improvements include support for module geometry, MRDIMMs for higher bandwidth, and Ultra Low Latency mode for reduced memory latency. However, the full performance gains may only be realized with AMD's upcoming Zen 6 processors. Asus has begun rolling out beta firmware with EXPO 1.2 support, signaling a commitment to enhancing the AM5 platform, though the full impact may not be felt until Zen 6 processors arrive in late 2026 or early 2027.
