| Step | Action | Why it works | | :--- | :--- | :--- | | | Re-paste with high-viscosity paste (Thermal Grizzly Kryonaut or Honeywell PTM7950). | Factory paste pumps out under high heat. | | 2 | Check mounting pressure. Screw until firm stop (no gaps). | Even 0.1mm gap kills thermal transfer. | | 3 | Update BIOS to latest version. | Fixes over-voltage bugs (the real "patch"). | | 4 | Set Pump to 100% in BIOS. | Variable pump speed causes thermal spikes. | | 5 | Apply an undervolt via software. | Reduces wattage without reducing clocks. | | Factory paste pumps out under high heat
