This long-tail hardware topic is for miners trying to improve reliability and efficiency. Please share temperatures, cooling ideas, maintenance habits, tuning choices, and what changed the result in practice.

Topics like this are strong because they are specific enough to be useful but common enough that a lot of miners will look for them.

The best replies here will probably be the ones that mention the exact machine, conditions, and what changed after each test.

This would be a very useful thread if people include real settings, temperatures, uptime behavior, and what the dashboard was showing.
