Coda56 modem getting hot after eight months (rough workaround).
I thought the Intel cooler would always be the top choice, but it turned out quite surprising. Using a larger metal plate seems excessive; a smaller finned heatsink would likely work better by improving airflow and convection, while also keeping more space for RAM. Their design clearly misses opportunities for efficient cooling.
It's the most affordable modem available on the Comcast approved list for mid-split installations (to boost upload speeds). The price difference is significant, indicating that cost savings are prioritized over other factors. The plate is clearly made of steel, with a magnet attached; scratching the paint reveals the metal matches the steel tone. A better heat conductor would likely be more expensive, adding a few dollars. I suspect my problem stems from the board warping slightly, widening the space between the chip and the heat sink.
In short, the modem isn’t very good, so it’s best to avoid using it. What I’ve learned is that only Node + 0 zones can get mid split; everyone else will have to wait until Docsis 4 comes out. The current modems aren’t available yet, and Comcast hasn’t given clear details about rolling them out beyond a few select regions.
Comcast controls Sky in the UK. Have you learned about their push for Fiber? In certain regions they also provide Fiber services. This relates to funding tied to government grants. Currently, most areas rely on Docsis arrangements. Additionally, this is the firm that believes data limits are essential by 2024.
Good observation. The government rules require major telecom providers to share their networks with ISPs. Sky currently uses DSL, FTTP, and now an alternative fiber network. They've also been broadcasting TV via broadband for years as a satellite alternative. The free-to-air channel appears to be transitioning to internet streaming. It seems the goal is eventually selling off all spectrum to mobile carriers—this approach is inefficient with unicast delivery and could be challenging in rural regions.
It offers significant savings compared to other options on the approved list. After proper cooling, it functions as intended. Comcast recently changed their network policies, demanding customer-owned modems with specific features for mid-split approval. Even though my previous DOCSIS 3.1 model could technically support the upgrades, it couldn’t be updated for the higher upload speeds on their system. If it fails completely, I’ll revert to my older device and forgo the extra speed, which is mainly needed when uploading videos to YouTube.
@MartyS Appreciate your documentation on this modem. There are numerous accounts of this model performing well at first, only to encounter frequent issues after months of use in irregular patterns. I’m curious if you’ve received any updates regarding your solution. Is the device still operating as intended? I’m weighing options between this unit, the Arris S34, and the Motorola SB8611 for a DOCSIS 3.1 / 2.32 Gbps upgrade. The two alternatives are priced twice as much. If maintaining functionality only requires adding a side-mounted case fan, that seems like a reasonable compromise.
It functions smoothly with the Pentium III cooler installed. Achieving 930Mbps down and 175Mbps up in speed tests confirms everything is operating well. The performance aligns closely with my 800/150 plan, indicating optimal setup. Nearly reaching the maximum of my 1G Ethernet connection during downloads, though actual household downloads seldom exceed 850 Mbps. Upgrading router, switches, or PCs to 2.5G isn’t on the agenda just yet. If a severe heat wave occurs this summer, I might add a small fan to the cooler for extra cooling.
