Whatsminer M21S's all-in-one heat sink can help increase M21S stability and efficiency, thus increasing profitability. High-quality M21S oxidized heat sink, super corrosion-resistant, ultra-thin and dense fins have better heat dissipation effect, each piece is treated with an anodic oxidation process, the surface is smooth and durable, and it is not easy to be contaminated with impurities. Compared to the cost of frequent M21S heatsink replacements, the M21S retrofit heatsink saves money while increasing lifespan. You will no longer need to repeatedly repair and replace chips or hash boards, saving maintenance time and costs, getting more efficient miners, and better selling prices. However, these repairs are likely to be ongoing and costly to miners in terms of downtime and repair costs. Plus, it could be damaged again when it returns for repair. Therefore, it is better to choose the M21S all-in-one radiator to maintain the miner. It can also help miners effectively solve the problem of falling off and missing heat sinks and make the M21S miners run more stably.
