Is the Hyper 612 APEX causing crashes in Rainbow Six Siege?
About two hours into a session, the system would just black-screen and reboot without warning. The unpredictability of these crashes had me totally on edge. I checked the logs and found the Cooler Master Hyper 612 APEX base wasn't making even contact; the temp delta between Core 0 and Core 4 was a shocking 15℃, triggering the thermal shutdown. I tried lowering the CPU power limit to 65W via software, but my FPS tanked from 144 to 90, which was a dealbreaker for competitive play. I ended up ripping the cooler off, applying a high-end paste with 13.5 W/mK conductivity, and tightened the brackets in a strict diagonal pattern. In OCCT, that 15-20℃ delta dropped to 5-8℃, with max temps staying around 76-82℃. I actually over-tightened the brackets on the second try, which slightly warped the board and caused a RAM detection error until I backed off the right screw by half a turn. Now the fans spin at 1100-1400 RPM and everything is efficient. The crashes stopped, and the mouse input feels way more responsive.
