Issues with heating sinks on motherboards
Issues with heating sinks on motherboards
I recently replaced the cooler on my CPU and after that the computer began shutting down during extended high-load sessions (over an hour). When it powers off it restarts and then turns off again, resembling a temperature issue, especially around the middle heatsink shown. Installing cooling fins didn’t resolve the matter. What options do I have now? My CPU remains comfortably below 70°C even under artificial stress (8x during a continuous script), and the GPU stays under 80°C. The airflow appears to move from the lower front (bottom right) to the upper back (top left). The board model is B85M-D3H rev 1.2. It crashes even with normal load: Discord, Steam updates, and YouTube.
I think the issue likely stems from the board's age rather than overheating. Heat could be contributing if certain capacitors are deteriorating, which usually happens when components warm up and perform less efficiently. Remember, B boards are budget options, so they might use lower-quality parts compared to premium models. This often means a shorter lifespan, particularly if they've been operating under high temperatures. Over time, older boards become increasingly unreliable, making their failure more predictable.
it's an i7-4770 with default configurations, maintaining CPU temperatures under 65°C even during maximum workload. According to Openhardwaremonitor logs, the temperature sensor near the VRM approaches 50°C prior to failure.
