Fixing VRAM overheating on Gigabyte RTX 5060 in Forza Horizon 5?
Cruising through Mexico at 4K, I kept noticing these micro-stutters that were just jarring when you're expecting 120 FPS. The core temp on my Gigabyte RTX 5060 Gaming OC was fine at 65℃ - 70℃, but the VRAM was oscillating between 88℃ - 95℃, triggering the memory controller to downclock. I tried low-power mode in the drivers, but that just cost me 15 FPS without solving the heat issue. I used MSI Afterburner to force the fans to 65% at 60℃ and added two high-pressure intake fans to the front of the case. Now, the VRAM temp variance has shrunk from 15℃ to just 4℃, and frame times are flat again. The fans were causing some backplate vibration at first, but some rubber dampening pads sorted it out. Core temps are now 62℃ - 68℃, and 3DMark confirms the VRAM clocks are no longer jumping, staying stable at 82℃ - 86℃.
