Thermals & sustained testing/DIY pitfalls
Key Questions
What thermal risks are associated with high-end GPUs like the RTX 5090?
Riser cable melting concerns and hotspot temperatures up to 107°C have been noted, prompting modding discussions and Afterburner heatmap updates. Practical case selection based on GPU power draw is recommended.
Does passive cooling work for modern GPUs like the RTX 4060?
A 5.5-pound aluminum heatsink mod on an RTX 4060 achieved convection-only cooling in testbench setups, though power draw accuracy questions remain. This serves as an experimental DIY option rather than mainstream advice.
How can laptop owners improve thermals on models like the ASUS G513QR?
Cleaning fans and replacing thermal paste can reduce high idle temps around 93°C, with PTM7950 suggested as an effective material. Step-by-step guides provide practical DIY maintenance steps.
What sustained performance data exists for laptops like the Lenovo Legion 9i?
Thermal testing shows the Legion 9i maintains 160W CPU and 175W GPU loads without major throttling. This highlights its capability for extended high-performance sessions.
How does vertical GPU mounting affect thermals and case choice?
Vertical mounting resolves some clearance issues but can introduce new airflow or compatibility concerns depending on the case. Reviews of models like the Cooler Master HAF II 500 emphasize matching case design to GPU power.
