How to stop Jonsbo CR-1400E from overheating in Metro Exodus?
Every time I panned across the snowy wasteland, my frames would dive from 90 down to 40. It was honestly anxiety-inducing. The Jonsbo CR-1400E is a compact unit, and it just can't handle 180W+ spikes, causing temps to jump from 70℃ to 95℃ in a heartbeat. I tried the 'Power Saver' plan in Windows, which lowered temps but killed my minimums to 20 FPS—a total fail. I went into the BIOS and capped PL1 at 125W and PL2 at 150W, while forcing the fan to 2200 RPM once it hits 80℃. In side-by-side tests, I lost about 0.2GHz in peak clock, but the frame time variance shrank from 12-45ms to 10-16ms, killing the stutter. I did experience two random reboots when I first set the power limits, but a slight Vcore offset of +0.02V stabilized everything. CPU stays between 82℃ - 88℃ now. The performance analyzer shows a flat frequency curve, and the input lag feels way more responsive.
