Thermal throttling on your i9 is really frustrating. Let me know if you need assistance.
Thermal throttling on your i9 is really frustrating. Let me know if you need assistance.
I already had arctic mx-4 thermal compound and changed it for safety. Now idle temps are fine, but under full load they hit about 95°C—only around 85°C at 100% load, dropping to 90–91°C after long use. Would you mind if I consider repasting with liquid metal? If using a 42x multiplier on XTU temps, keeping them below 90°C at 100% load, how can I adjust the undervolt and ratio settings after boot without opening XTU and doing manual tweaks?
I conducted several tests and consistently observed that the top four cores (4, 5, 6, and 7) maintained the highest temperatures during stress testing at full load. The other four cores stayed within a comfortable range, with 95°C being the maximum throttle limit. It seems unusual that distributing the workload evenly across all CPUs and clock speeds results in similar temperatures. This behavior might be related to how Intel i9 processors manage heat dissipation in laptops.
It's not unusual for thermal compound to spread slightly during installation. The horizontal line you mentioned might have helped guide it. The pressure from the heatsink could also play a role. Check if the application was even and consistent.
It's how CPU designs generally function. Check the die layout: four cores are centered, with ones on either side, while two sit at the ends of each side. The cores in the middle will probably get warmer... _____ |0xx0| |0xx0| ------- The dots here are clustered in the center of the zeros, making it harder to release heat and absorb some from the surrounding areas.
I swapped it in with condctonaut and the performance is now stable. During play it's roughly 82 - 88°C whereas before it was consistently 90 - 95°C even under lighter load. I managed to lower the voltage down to -105mV stably before, but anything higher caused crashes. There are no big jumps in core temperatures now. With the undervolt setting, my multicore score on Cinebench R20 went up to around 4200 (temps near 90°C, turbo at 3.9 or 4GHz after short power cut) and with -105mV it exceeded 4450 (temps about 88°C, turbo at 4.0 or 4.1GHz). Before that, under 3700°C even at full load, and throttling stayed at 95°C always. Now the GPU temps are climbing a bit more during gaming (around 80 - 83°C), but no throttling occurs when it hits 1850 - 1915MHz with over 90% usage. I suspect this is normal since the system shares a heatpipe between CPU and GPU, and all components might benefit from better thermal conductivity through the shared die to the heatsink. That could explain the slight rise in GPU temps compared to before (around 78°C). It's also possible that the cooler you installed helped keep GPU temps around 90°C max. After replacing the TIM on the GPU with Arctic MX-4 spread method and applying conductoaut to the CPU, things seem to be improving. The GPU temperature is just under 75°C during benchmarks with 3D Mark Timpsy and FireStrike. Overall the performance is excellent and surpasses what I've seen in reviews online.
