How to fix frequency jumping on Noctua NH-D15 G2 in CS2?
My fingers were flying across the mouse, but the screen had these micro-second tears at the worst possible moments. In a competitive shooter, that lack of fluidity is basically a death sentence. Looking at the logs, CPU core temps were swinging wildly between 65-78℃, which is insane because the NH-D15 G2 should easily keep things under 60℃. I tried capping the boost clock to 4.8 GHz via software, but while it cooled down, my FPS tanked from 400 to 310—a totally irrational trade-off. I decided to rip the cooler off and found the stock paste had uneven gaps after mounting. I swapped it for a 0.12mm liquid metal thermal interface. After tightening everything down, core temps dropped to 52-58℃ under the same load, and frame times locked into a tiny 2.1-2.5ms window. I actually messed up the second install by over-tightening the screws, which slightly warped the PCB and caused the system to lose a RAM channel; I had to back the screws off half a turn to get dual-channel memory back. Now, fans spin at 800-1100 RPM and it's dead silent. Two hours of OCCT stress testing confirmed a flat frequency curve, with memory temps holding steady at 52-58℃.
