The Whatsminer M50 is a top-tier mining rig known for its reliability, but it’s not immune to issues like the Whatsminer M50 350 error. This overheating error, often caused by dust and debris buildup, can disrupt your mining operation. Fortunately, with proper maintenance, you can resolve the whatsminer M50 350 error and keep your Whatsminer M50 running smoothly. Here’s how to tackle this issue and prevent costly repairs.
Why Does the Whatsminer M50 Overheat?
The M50 350 error is typically triggered by an overheating error, where dust, bugs, or poor ventilation clog the miner’s components. Many miners don’t realize how much debris can accumulate inside a Whatsminer M50, especially in dusty or humid environments. This buildup blocks airflow, causing the chips to overheat, which can lead to performance issues or even permanent damage if ignored.
For instance, we’ve seen a Whatsminer M50 in a well-organized mining container still collect heavy dust and bugs, despite having intake and exhaust fans. This clogged airflow caused persistent M50 350 errors and related 360 errors, both tied to excessive heat.


The Dangers of Ignoring the M50 350 Error
When a Whatsminer M50 encounters a 350 or 360 error, it may continue hashing but will repeatedly restart due to the overheating error. This cycle generates more heat, stressing the chips and risking serious damage. If left unaddressed, the M50 350 error could lead to repair costs of several hundred dollars. Catching it early, however, can save you from expensive fixes.

How to Fix the Whatsminer M50 350 Error
To resolve the M50 350 error, start by opening the Whatsminer M50 and thoroughly cleaning it. Remove dust and debris from the hashboards and fans to restore proper airflow. Next, reapply thermal paste to all three hashboards to improve heat dissipation. In our experience, cleaning and reapplying thermal paste fixed a Whatsminer M50 with this overheating error, restoring it to full performance. While this approach isn’t guaranteed to fix every hashboard issue, it’s the first step to try.
As shown on the dashboard, after cleaning and reapplying thermal paste to all hashboards, the temperature decreased significantly, and the miner resumed hashing efficiently.

Preventing Future Overheating Errors
Regular maintenance is key to avoiding the M50 350 error. Clean your Whatsminer M50 regularly, especially if it’s in a dusty or bug-prone environment. Reapply thermal paste based on your site’s conditions—more frequent cleaning may be needed in harsher setups. Proper maintenance ensures better airflow, reduces heat, and extends the lifespan of your hashboards, keeping your Whatsminer M50 hashing efficiently.
By addressing the M50 350 error promptly and maintaining your miner, you can avoid costly repairs and keep your Whatsminer M50 performing at its best.
