How to fix Jonsbo CR-1400 thermal crashes in Minecraft RTX?
I was working on a complex redstone circuit and the game just vanished back to the desktop. It's a real mood-killer. The crash logs showed Core 0 was way hotter than the rest; the Jonsbo CR-1400 ARGB White Edition just couldn't dissipate that specific hotspot, causing voltage to swing between 1.1V and 1.3V. I tried increasing the page file size, but that did nothing—it actually started crashing every ten minutes. I realized this was a physical problem. I checked the base and found the factory finish was slightly convex, reducing contact area. After some light sanding and fresh paste, the core delta dropped from 18°C to 6°C. In OCCT, temps stayed between 76°C - 82°C with voltage ripples under 0.02V. I tried a -0.1V offset at first, but the system wouldn't even POST. I backed it off to -0.05V and it finally worked. Fans are running at 1700-2000 RPM, and after 4 hours of testing, zero crashes.
