Lenovo IdeaPad Gaming 3 15ACH6
Thermal Guide · Laptop Database
Model-specific cooling and thermal-maintenance reference. Exact hardware variants are kept separate before applying thermal measurements.
Internal View — Reference
Reference configuration: Lenovo IdeaPad Gaming 3 15ACH6 · AMD Ryzen 5 5600H · NVIDIA GeForce GTX 1650.
This internal image is a temporary external teardown reference. It is not a Fix&Run-verified thermal map and must not be used as a definitive pad-thickness measurement.
Fix&Run verification: The reference image will be replaced/updated with our own internal photography and measured thermal map once the exact device is available.

Thermal Interface Data
Fix&Run verified: Direct measurement pending.
Community-reported pad measurements: 0.75mm, 1.5mm, 3mm and 4mm were reported by a Reddit user who stated they measured the pads with a caliper. Other community reports mention 0.5–1.5mm replacement pads.
Important: These are community reports, not Fix&Run-verified measurements. Thickness can vary by component location and configuration.

Thermal paste: Required after heatsink removal; the exact material used will be documented after Fix&Run verification.
PTM: Community reports include PTM 7950 use; currently classified as community information.
Liquid metal: No recommendation published yet for this model. Compatibility and application risk require exact-assembly verification.

Verification & Sources
Manufacturer: Lenovo PSREF lists the 15ACH6 family with Ryzen 5 5500H / 5600H and Ryzen 7 5800H processors, plus GTX 1650 through RTX 3060 graphics options depending on configuration.
Community: Reddit reports provide useful pad measurements and repaste experiences, but are clearly separated from manufacturer data.
Fix&Run status: First draft complete. Fix&Run verification status: configuration data is manufacturer-based; thermal pad thickness remains pending direct measurement.
Recommended materials for this platform: use only the thickness confirmed for the exact heatsink/component location. Do not substitute a pad thickness based only on another 15ACH6 configuration.
Recommended Fix&Run products:
Fehonda Thermal Pad 15W – 0.5 / 0.75 / 1 / 2mm
Fehonda Thermal Pad 0.75mm 15W
Fehonda Thermal Pad 2mm 12.8W
Fehonda Liquid Thermal Pad 16W/m·k
Important: these products are listed as material options, not as a claim that every listed thickness is correct for every component on this laptop. The final selection must follow the verified thermal map for the exact board/heatsink variant.
