UnverifiedCPU与GPU的功耗需匹配整机散热上限：14英寸小机身选i9/R9+RTX4070会因散热墙导致双烤降频，14寸首选中端U（R7 8845HS/i7-14650HX）搭配60-90W显卡更均衡82% similarUnverified标称导热系数≥8.5 W/m·K的硅脂适合高端CPU/GPU（如i7/i9、RTX4070以上）满载散热；日常办公和轻度使用选择4-6 W/m·K即可，标称过高的产品实测常有虚标81% similarUnverified供电相数与散热直接影响CPU持续性能：搭配i7/R7及以上不带核显的CPU，建议供电≥12+2相且带实心装甲散热片，否则高负载易触发降频80% similarUnverifiedi9-14900HX性能释放依赖散热条件，天选5 Pro的散热模组能维持较高功耗但长时间烤机下CPU会有一定降频，实际日常游戏场景影响不大79% similarUnverified散热性能释放看整机功耗(TDP)而非CPU型号：同样i7-13700H，性能释放可从35W到75W不等，购买前查实测双烤数据，CPU单烤≥55W才算释放到位79% similar
