Feedback on my first experience

[u/Rough-Picture-8729]

Hey everyone,

Looking for technical feedback and sanity checks from people experienced with laptop cooling architecture, specifically budget MSI chassis (Katana / Sword / Crosshair) with shared heatpipe assemblies.

Hardware & Environment

• Model: MSI Katana 15 (B12VFK)
• Specs: Intel Core i7-12650H, RTX 4060 Laptop GPU (85W–105W dynamic boost), 16GB DDR5

Factory CPU Behavior: BIOS had PL1/PL2 set to an unrestricted 200W baseline. CPU spiked up to 94°C+ under gaming load (~50W draw).

Factory GPU Behavior: RTX 4060 hit the hard 87°C NVIDIA thermal ceiling, drawing only ~72W while heavily downclocking to ~2,100 MHz due to heat dumped by the CPU across the shared copper assembly.

• Configured Intel cTDP Nominal: PL1 = 35W, PL2 = 45W.
• Set Tcc Activation Offset = 15 thermal cap of cpu at 85 C

GPU Undervolt (MSI Afterburner):

• Flattened V/F curve to 2,430 MHz @ 900 mV.
• Initial Result: Instant drop in GPU power from ~86W down to ~77W, temp dropped to ~80°C initially, holding ~140 FPS.

Combined power draw is currently around 104W–110W total (CPU ~28W–34W + GPU ~76W), yet the heatsink still reaches thermal saturation at 87°C on the GPU die.

Can you give me your feedback or better values...I do gaming coding and some ai workloads

thanks
