A modder has taken the concept of passive cooling to the extreme, attaching a massive 2.5kg heatsink to an RTX 4060 graphics card. This bold move, showcased on the Chinese platform Bilibili, aims to prove that even high-performance GPUs can be cooled without fans. The heatsink, made of finned aluminum, dwarfs the card and the mini-ITX motherboard it's mounted on, weighing more than twice the card's weight. This setup, while impressive, raises questions about the practicality of such an extreme approach to cooling.
The modder's choice of the RTX 4060 is strategic. With a 115W TDP, it's relatively low compared to other GPUs like the RTX 5060 (145W) and RTX 5090 (575W). This makes it a suitable candidate for a fanless cooling experiment. However, the modder's decision to go fanless comes with tradeoffs. Passive cooling, while quieter, often doesn't match the temperature control of active cooling. The article mentions a previous build where an RTX 4060 was cooled to around 80-85C under load, which is still within acceptable limits.
The DIY community has embraced passive cooling, with examples like a Redditor's passive RTX 3080 setup using ten tower heatsinks and fanless small form factor builds powered by AMD's Strix Halo APU. Even case makers are getting in on the action, like Streacom's SG10 chassis designed to dissipate up to 600W without fans. These builds are more about showcasing the possibilities of passive cooling rather than practical applications.
While the 2.5kg heatsink setup is an impressive feat of engineering, it's not a practical solution for most users. The article emphasizes that such builds exist to explore the limits of passive cooling, not as a practical solution. The modder's achievement is a testament to the potential of passive cooling, but it remains a niche interest for enthusiasts who enjoy pushing the boundaries of hardware modification.
