| Video Discription | Transform your Mellanox CX5 100G Network Card with a $2 upgrade for cooling, reducing temperatures by 20 degrees and effortlessly stepping into the era of home 100G high-speed networking! The 100G network card generates a significant amount of heat. Unlike server environments with powerful fans for direct cooling, home setups may not have the same cooling capabilities. If the PC case has poor ventilation and the network card reaches 115 degrees Celsius, it will automatically shut down the card's functionality, causing the system to lose the network card and interrupting the network connection. This time, with a $2 purchase that includes shipping, we've acquired a cooling plate with an integrated cooling fan. The upgrade to the ConnectX-5 network card's cooling system has dropped the temperature by more than 20 degrees compared to the original cooling plate, ensuring that the 100G network card can operate stably and long-term in a home environment. The Mellanox ConnectX series of network cards, including the CX4, CX5, and CX6 models, all come with the same original cooling plate dimensions of 60x55mm. This cooling plate is also compatible with the full series of Nvidia Mellanox original CX4, CX5, and CX6 PCIe network cards. Mellanox CX4, CX5, and CX6 come with fan-assisted heatsinks. The original store offers two versions: one is a standard 4010 framed version, and the other is a frameless fan version. I purchased both versions for testing. The older 4010 standard framed fan version did not reserve enough height at the bottom for air passage, resulting in poor heat dissipation. Later, at my request, the owner improved the craftsmanship. The framed fan version has raised the fixing screws by 0.5mm, and an air channel was machined under the fan. Since the fan blows directly onto the heatsink, and the reserved 0.5mm air channel squeezes the airflow, it significantly increases the air velocity. The strong wind directly carries away the heat from the heatsink, markedly improving the cooling effect. The air speed is higher than that of the frameless version, providing more direct heat dissipation. The actual measured effect is already better than the frameless version. Moreover, because the high-quality framed 4010 fan is easier to purchase and modify, it is more recommended to buy the framed fan version. The store now ships the version with the improved air channel, so you can confidently purchase the 4010 framed fan version. Based on my actual tests, purchasing M3 1.2mm spacers and adding two more 2.4mm spacers, the fan is about 3mm away from the heatsink, and the network card temperature can drop by more than 5 degrees, achieving the best cooling effect. This is suitable for users who pursue the ultimate cooling performance. For any questions related to Mellanox network cards or 100G networking setups, please discuss and leave a comment in the section below. Stay tuned for the next video, which will feature a silent home upgrade for the Mellanox SN2100 100G switch on the networking side. Don't miss it! 10元改造迈络思cx5 100G网卡散热，狂降20度，轻松迈入家用100G高速时代！ 100G网卡发热量大，家用环境不像服务器，有暴力风扇直吹散热。 如果机箱通风性不好，网卡达到115度，则会自动关闭网卡功能，造成系统里面掉网卡，网络中断。 这次10块包邮购买了带散热风扇的散热片， 改造ConnectX-5网卡散热，温度比之前原装散热片低了20多度， 这样100G网卡就能够在家用环境长期稳定运行。 Nvidia迈络思ConnectX系列网卡，cx4、cx5、cx6系列原厂散热片尺寸都一样， 规格为 60x55mm， 此散热片也适用于Nvidia迈络思原厂cx4、cx5、cx6全系列PCIE网卡。 迈络思cx4、cx5、cx6带分风扇散热器，原店铺有2个版本，1个普通4010有框版本、1个无边框风扇版本。2个版本我都买了测试，由于老版本4010普通有框风扇底部没有预留足够高高度风通，散热效果很差。 后来在我的要求下，老板改进了工艺，有框风扇版本固定螺丝垫高了0.5mm，同时在风扇下方机床洗出了风道，因为是风扇直吹散热片，同时预留的这个0.5mm风道挤压气流，明显提升了气流的流速，强劲的风力直接带走散热片上的热量，散热效果显著提高。 气流速度比无边框速度更高，更直接散热，实测效果已经好于无边框，而且由于高质量有框4010风扇更容易买到和改造，所以更推荐买有框风扇版本。目前这个店铺出货的也都是改进风道的版本了，所以可以放心购买4010有框风扇版本。 同时根据我实际测试，购买M3 1.2mm垫片，再垫高2个垫片2.4mm高度，风扇离散热片高度3mm左右，网卡温度还能下降5度以上，散热效果最佳，适合于追求极致散热效果的用户。 有关迈络思网卡、100G组网的相关问题， 请评论区讨论、留言。 下期视频将带来网络侧100G迈络思SN2100交换机家用化静音改造，敬请期待。 |
