Problem
An NVMe drive is installed beneath a GPU backplate with inadequate airflow, creating a localized thermal hotspot during exports.
Solution
Root Cause / Diagnostic:
Positioning an NVMe media SSD in an M.2 slot sandwiched directly beneath a high-TDP graphics card traps heat. During video rendering, the GPU exhaust dumps 60–75°C hot air directly onto the SSD heatsink, pushing the SSD controller past 85°C and causing emergency read/write throttling.
Actionable Fix:
1. Drive Relocation: Move the media NVMe SSD to an unobstructed M.2 slot located away from the primary PCIe GPU exhaust zone, or install it on a dedicated PCIe expansion card in a lower slot.
2. Case Airflow Optimization: Install high-static-pressure intake fans at the front and bottom of the workstation chassis to direct cool air across the motherboard surface.
3. Stress Export Thermal Profiling: Run a 30-minute 4K DaVinci Resolve render while logging GPU and SSD temperatures to confirm SSD controller thermals remain stable under 70°C.
Pro Tip:
Never install your primary cache or media SSD under the GPU exhaust; use a PCIe add-in-card (AIC) to mount the SSD in the lower slot where case intake fans supply fresh, cool air.
