Can I ask about the thermal design principles of the Poco series under high loads? How do the heat pipe layout and heatsink material work together? What impact does software-level power consumption scheduling have? How do these mechanisms affect the CPU and GPU temperature curves? Are there any general user-side optimization methods to improve cooling efficiency? Any experiences or suggestions from you guys?
How does the heat dissipation design principle of the Poco series relate to its actual performance? In high-load scenarios?

The Poco series still relies on copper heat pipes + aluminum/graphite composite heatsinks for core cooling under heavy loads. The heat pipes are typically arranged in a V-shape on either side of the chip, with the ends closest to the CPU and GPU heat sources directly contacting the heatsink fins to maximize thermal conduction area. In terms of heatsink materials, earlier generations used pure aluminum, while later models switched to graphene-reinforced aluminum matrix composites, improving heat dissipation speed while maintaining the same overall thickness for a balance between thinness and cooling performance. On the software side, power consumption is managed using a Gaussian scheduling strategy (Gauss Scheduler), which temporarily lowers the frequency of non-critical cores during sudden system load spikes to keep core temperatures within safe limits. Meanwhile, the GPU’s dynamic frequency scaling (DVFS) proactively reduces clock speeds when temperatures approach the upper threshold to prevent thermal throttling.
When running *Genshin Impact* on my Poco X4 Pro, the CPU temperature hovers around 45 °C, while the GPU stays around 50 °C—thanks to the evenly distributed heat pipes and the graphite heatsink’s rapid heat diffusion. Through real-world use, I’ve found a few tricks to further improve cooling:
1. **Replace the thermal paste** with a high-conductivity option (e.g., T-Global or Thermal Grizzly) to reduce chip-to-heatsink thermal resistance by about 10%.
2. **Enable "Force GPU Frequency Cap"** in *Settings > System > Developer Options* (set to ~800 MHz) to prevent short-term temperature spikes from peak power draw.
3. **Disable unnecessary high-frequency background services** (e.g., OneDrive sync, real-time backups) to lower overall system power consumption.
4. **Use an external cooling frame or attach a thermal pad** to the back of the device during long gaming sessions to help dissipate heat more efficiently.
Combining these hardware tweaks with software and accessory adjustments results in smoother temperature curves and significantly reduces throttling during intensive gaming. Hope this helps—feel free to share your own experiences or tips!
